Embodiment one

FIG. 1 is a schematic flowchart of a method for adjusting target recognition frequency in augmented reality provided by Embodiment 1 of the present invention. The method is suitable for regulating the target recognition frequency in augmented reality when a user uses a mobile terminal to shoot based on augmented reality. In the case of , it can be performed by an apparatus for adjusting target recognition frequency in augmented reality, where the apparatus can be implemented by software and/or hardware, and is generally integrated in a mobile terminal.

As shown in Figure 1, a mobile terminal anti-addiction method provided by Embodiment 1 of the present invention specifically includes the following operations:

S101. Monitor whether the current performance index value of the mobile terminal meets a corresponding reference threshold condition.

In this embodiment, the mobile terminal may specifically refer to smart electronic devices with a camera function, such as mobile phones, notebooks, and tablet computers. In this embodiment, the performance index value may specifically be used to evaluate the working performance of the mobile terminal. Exemplarily, if the performance index value hardly changes when the mobile terminal is in the standby state or the performance index value changes smoothly when the mobile terminal is in the working state, it can be considered that the mobile terminal has good working performance .

In this embodiment, each performance index value of the mobile terminal has a corresponding reference threshold value condition. Generally, the reference threshold value condition can be specifically understood as a critical condition for judging whether each performance index value is within the normal working range. . Exemplarily, the reference threshold condition for setting the remaining power is: the remaining power is not less than 40% of the total power, then when the current power remaining of the mobile terminal is 49% of the total power, it can be considered that the current The remaining amount of battery power meets the corresponding benchmark threshold condition, that is, the current remaining battery power is in the normal range; for another example, the benchmark threshold condition for setting the processor resource occupancy rate is: the processor resource occupancy rate is not higher than 60%, Then when the current processor resource occupancy rate of the mobile terminal is 65%, it can be considered that the current processor resource occupancy rate does not meet the corresponding benchmark threshold condition, that is, the current processor resource occupancy rate is too high and does not meet the normal scope.

Further, the performance index value includes: one or more of remaining power, processor resource occupancy, and running memory resource occupancy.

In this embodiment, the working performance of the mobile terminal is mainly reflected based on the performance index value of the mobile terminal. Common performance index values include: the remaining battery capacity of the mobile terminal, the occupancy rate of processor resources, and the occupancy rate of running memory resources. In this embodiment, the standby time of the mobile terminal can be determined based on the change speed of the remaining amount of power; The level of processing efficiency in the state.

S102. If the performance index value does not meet the corresponding reference threshold condition, when the mobile terminal is in the augmented reality shooting mode, adjust the recognition frequency of target object recognition in augmented reality based on the mobile state of the mobile terminal.

In this embodiment, the mobile terminal is in the augmented reality shooting mode. Specifically, it can be understood as: the augmented reality technology is integrated into the photographing function application of the mobile terminal, so that the user can take pictures in real time based on the camera of the mobile terminal. Effect or scene enhancement on the target object in the image frame in the camera preview interface. It should be noted that the first prerequisite for performing effect or scene enhancement on the target object is to be able to identify the target object in the image frame in the camera preview interface. Generally, when the mobile terminal is in the augmented reality shooting mode, the target object recognition is usually continuously performed on the image frames in the camera preview interface, that is, the target object recognition in augmented reality has a very high recognition frequency, thus Continuously consume the power of the mobile terminal and occupy the space resources of the mobile terminal processor and running memory.

In this embodiment, if it is monitored that the current performance index value of the mobile terminal does not meet the corresponding reference threshold condition, it may be considered that the current performance index value does not meet the normal working range. When it is determined that the current performance index value does not meet the corresponding benchmark threshold condition, if the target object recognition is still performed on the image frames in the camera preview interface based on the original recognition frequency, the power consumption and/or the occupation of space resources will be increased , so that the performance index value of the mobile terminal is always in an abnormal state, thereby affecting the working performance of the mobile terminal. Therefore, it is necessary to adjust the recognition frequency of target object recognition.

In this embodiment, when the current performance index value does not meet the corresponding reference threshold condition, the recognition frequency of the target object recognition can be adjusted based on the mobile state of the mobile terminal, so as to slow down the power consumption of the mobile terminal and/or reduce the processor and The resource usage of running memory. Wherein, the moving state of the mobile terminal may specifically include a moving state of the mobile terminal and a stationary state of the mobile terminal. Specifically, the recognition frequency of the target object can be adjusted by judging the movement state and speed of the mobile terminal, or the recognition frequency can be adjusted based on a set adjustment means when the mobile terminal is in a stationary state.

Embodiment 1 of the present invention provides a method for adjusting target recognition frequency in augmented reality. First, monitor whether the current performance index value of the mobile terminal meets the corresponding threshold-based condition. , adjusting a recognition frequency for recognizing a target object in augmented reality based on the moving state of the mobile terminal. With this adjustment method, when the performance index value of the mobile terminal does not meet the reference threshold condition, the recognition frequency of the target object recognition in the augmented reality can be adaptively adjusted, so that the augmented reality operation will not occupy too many items of the mobile terminal. The performance index value, thereby ensuring that the mobile terminal has good working performance without affecting the performance of the augmented reality shooting operation.

Embodiment two

Fig. 2a is a schematic flowchart of a method for adjusting target recognition frequency in augmented reality provided by Embodiment 2 of the present invention. Embodiment 2 of the present invention is optimized on the basis of the above embodiments. In this embodiment, the step "adjusting the recognition frequency of the target object in augmented reality based on the moving state of the mobile terminal" is further embodied as: determining the moving The mobile state of the terminal; if the mobile terminal is in a stationary state, adjust the recognition frequency of target object recognition in augmented reality based on the first adjustment rule; if the mobile terminal is in a moving state, then adjust the recognition frequency in augmented reality based on the second adjustment rule The recognition frequency for target object recognition.

As shown in Figure 2a, a method for adjusting target recognition frequency in augmented reality provided by Embodiment 2 of the present invention specifically includes the following operations:

S201. Monitor whether the current performance index value of the mobile terminal meets a corresponding reference threshold condition.

Exemplarily, monitor one or more performance index values among the current power remaining amount, processor resource occupancy rate, and running memory resource occupancy rate of the mobile terminal to determine whether the monitored performance index values meet the corresponding benchmark thresholds condition.

S202. If the performance index value does not meet the corresponding reference threshold condition, execute steps S203 to S205.

Exemplarily, when one or more of the performance indicator values in the monitored mobile terminal's current remaining battery capacity, processor resource occupancy rate, and running memory resource occupancy rate do not meet the corresponding baseline threshold conditions, continue to perform the following steps S203 to step S205.

S203. When the mobile terminal is in an augmented reality shooting mode, determine a moving state of the mobile terminal.

In this embodiment, after the camera function of the mobile terminal incorporating AR technology is activated, the mobile terminal can be considered to be in an AR shooting mode. Therefore, when the mobile terminal is in the augmented reality shooting mode, the current moving state of the mobile terminal can be determined, and the moving state generally includes a moving state and a static state.

S204. If the mobile terminal is in a stationary state, adjust a recognition frequency for target object recognition in augmented reality based on a first adjustment rule.

In this embodiment, the fact that the mobile terminal is in a static state can be specifically understood as that when shooting based on the camera, the picture displayed in the captured real picture frame is always the same picture, and at this time it can be adjusted based on the first setting Rules to adjust the recognition frequency of target object recognition in augmented reality.

Further, the adjusting the recognition frequency of the target object in the augmented reality based on the first adjustment rule includes: capturing the current real-scene picture frame based on the maximum resolution of the camera, and performing an operation on the real-scene picture frame based on the set first recognition frequency. Target object recognition.

In this embodiment, the maximum resolution of the camera may specifically refer to the highest pixel value of the camera. For example, if the highest pixel value of the camera is 8 million, it may be considered that the maximum resolution of the camera is 8 million.

In this embodiment, if the mobile terminal is in a stationary state, the current real-scene picture frame can be captured based on the maximum resolution of the camera. At this time, since the scenes displayed in different picture frames of the camera preview interface are the same real scene, The camera is easy to capture the real scene picture frame with clear faces; after that, quickly carry out the target object recognition on the real scene picture frame with the set first recognition frequency, because the picture of the real scene picture frame is clear, so based on the set first recognition frequency The first recognition frequency can quickly realize the recognition of the target object, and can quickly complete the effect enhancement of the target object.

Generally, the augmented reality shooting mode can be exited after the effect enhancement of the target object is realized. Therefore, the target object recognition is quickly performed on the real scene frame based on the first recognition frequency, and the effect enhancement of the target object is quickly completed. After that, you can quickly exit the augmented reality shooting mode; finally, you can quickly release the resources of the processor and running memory occupied by the augmented reality operation, and at the same time reduce the power consumption of the mobile terminal during augmented reality shooting. This achieves the effect of maintaining good working performance of the mobile terminal.

S205. If the mobile terminal is in a moving state, adjust the recognition frequency of target object recognition in augmented reality based on a second adjustment rule.

In this embodiment, the fact that the mobile terminal is in a moving state can be specifically understood as that when shooting based on the camera, the picture displayed in the captured real picture frame is always changing. At this time, the augmented reality can be adjusted based on the second adjustment rule The recognition frequency of target object recognition in .

Further, FIG. 2b is a flow chart of adjusting target recognition frequency in augmented reality based on the second adjustment rule provided by Embodiment 2 of the present invention. As shown in FIG. 2b, the second adjustment rule provided by Embodiment 2 of the present invention to adjust the recognition frequency of the target object in augmented reality specifically includes the following operations:

S2051. Determine the moving speed of the mobile terminal.

In this embodiment, when the mobile terminal is in a moving state, firstly, the moving speed of the mobile terminal may be monitored.

It should be noted that, if the mobile terminal is in a moving state, the resolution can be appropriately reduced when the camera captures the current real-scene picture frame, and the recognition frequency of target object recognition for the real-scene picture frame can also be correspondingly reduced, because When the mobile terminal is in motion, it is impossible to take clear images, and the effect of augmenting reality on unclear images is not good. Therefore, in order to save resource consumption, the resolution and recognition will be reduced accordingly when the mobile terminal is in motion. frequency. In addition, the resolution and the degree of reduction of the recognition frequency can be determined based on the speed of the movement.

S2052. If the moving speed of the mobile terminal is lower than the set speed value, capture the current real-scene picture frame with the set first resolution, and target the real-scene picture frame based on the set second recognition frequency object recognition.

In this embodiment, the monitored moving speed of the mobile terminal can be compared with a set speed value to determine whether the moving speed is lower than the set speed value, and if it is lower than the set speed value, then The current real-scene picture frame is captured with the set first resolution, and the target object recognition is performed on the real-scene picture frame based on the set second recognition frequency.

In this embodiment, if the moving speed of the mobile terminal is lower than the set speed value, it can be considered that the moving speed of the mobile terminal is relatively slow. In this case, the first resolution can be used to capture the current real scene frame , wherein, the first resolution is lower than the maximum resolution; at the same time, when the motion speed is low, although the picture of the captured current real picture frame is not clear, it is also possible to target the real picture frame Object recognition, but the current recognition frequency needs to be adjusted to a second recognition frequency, wherein the second recognition frequency is lower than the first recognition frequency. Since both the resolution and the recognition frequency used in the augmented reality shooting are reduced, the occupancy of the performance index during the augmented reality shooting is also correspondingly reduced.

S2053. If the moving speed of the camera is not lower than the speed value, capture the current real-scene picture frame with the set second resolution, and no longer perform target object recognition on the real-scene picture frame.

In this embodiment, if the monitored moving speed of the mobile terminal is higher than or equal to the set speed value, it can be considered that the moving speed of the mobile terminal is faster. In this case, the second resolution can be used rate to capture the current real scene picture frame, wherein the second resolution is lower than the first resolution; at the same time, when the motion speed is fast, the picture of the captured current real scene picture frame is due to the motion speed and the adopted At this time, the current real-scene picture frame is very unclear, and there is no need to enhance the effect of the target object in the real-scene picture frame, so there is no need to perform target object recognition on the real-scene picture frame. When , the target recognition frequency can be set to 0.

In this embodiment, because the resolution used in augmented reality shooting is very low and target object recognition is no longer performed, the occupancy of the performance index will be correspondingly reduced at this time, so that it can adapt to the current performance of the mobile terminal. Index value. Based on the above steps S2051 to S2053, it can be found that based on the mobile state of the mobile terminal, the recognition frequency of the target object in the augmented reality can be adjusted in a timely manner, thereby adapting to the current performance index value of the mobile terminal.

As shown in FIG. 2 c , when the mobile terminal is in a stationary state at this time, the current real-scene frame is captured with the maximum resolution of the camera, and the target object 21 can be recognized at the set first recognition frequency.

In this embodiment, FIG. 2d shows that the remaining power of the mobile terminal is 30%, which is lower than the reference threshold condition of 40% of the mobile terminal, and when the mobile terminal is in the augmented reality shooting mode, the camera is in motion when the mobile terminal is in motion. An example image of the current live-action frame captured in the state. As shown in Figure 2d, the moving state of the mobile terminal at this time is a moving state, and the moving speed at this time is higher than or equal to the set speed value, then at this time, the current real scene frame is captured with the second resolution of the camera , and no longer identify the target object 22, where the second resolution of the camera is much lower than the maximum resolution of the camera at this time, for example, if the maximum resolution of the maximum resolution of the camera is 8 million, then the The second resolution mentioned above is 2 million.
