Please refer to Figure 1, please refer to Figure 1, this application proposes a vehicle flooding early warning method, the method includes:

Step S101: Acquiring an image frame of a set position outside the vehicle. The image frame is mainly obtained by the camera sensor installed on the vehicle.

In this embodiment, the set position can be the front of the vehicle or a side of the vehicle, and the acquired image frame can be the image frame in front of the vehicle or the image frame on the side of the vehicle. There is no limitation in this application, and it may be an image screen of any side of the vehicle.

Step S102: Determine the reference target in the image frame.

In this embodiment, the reference target may be a white wall, or an upright pillar, or a stationary car opposite. The reference target is selected according to the actual situation. Generally, stationary objects are preferred, and the vehicle also needs to remain stationary. In short, the reference target should be selected when the vehicle remains stationary.

Step S103: Identify the flooding position in the image frame relative to the reference target.

In this embodiment, the location of flooding is identified through image recognition technology. Specifically, the position of the flooding in the image frame is determined by identifying the color of a continuous piece of the same pixel in the image frame. For example, if you select a wall as the reference target, there will be a continuous piece of white pixels in the image, but the water pixels are not white, and the water pixels are a piece of yellow or gray pixels. There are pixels of two colors in the center, and the pixels of water are generally below. By analyzing the position of the pixels of the water relative to the reference target on the image, the position of the water relative to the wall can be known, which is also the flooding position. In this embodiment, the height of the flooded position can be obtained through conversion according to the ratio of the image frame to the actual object and the ratio formula. For example, through image recognition technology, it is recognized that the 4-meter-high white wall has similar 800 pixels in the direction perpendicular to the ground, and after flooding, 400 pixels in the direction perpendicular to the ground change into other colors. At this time, the water level is expected to reach 2 meters.

Step S104: Determine whether the flooding position reaches the preset position. If the flooding position reaches the preset position, it is considered that the vehicle is in a dangerous state of flooding, and a flooding warning signal is sent to notify the user.

In this embodiment, the preset position is half of the height of the reference target in the image frame. When the flooding position reaches half of the height of the reference target in the image frame, it is considered that the vehicle is in a dangerous state of flooding.

In this embodiment, the flood warning signal is sent to the user's mobile terminal through the 2G/3G/4G network.

Please refer to Fig. 2, the present application proposes a vehicle flooding early warning method, the method includes:

Step S201: Acquiring an image frame of a set position outside the vehicle. The image frame is mainly obtained by the camera sensor installed on the vehicle.

In this embodiment, the set position can be the front of the vehicle or a side of the vehicle, and the acquired image frame can be the image frame in front of the vehicle or the image frame on the side of the vehicle. There is no limitation in this application, and it may be an image screen of any side of the vehicle.

Step S202: Determine the reference target in the image frame.

In this embodiment, the reference target can be a white wall, an upright pillar, or a stationary car on the opposite side. The reference target is selected according to the actual situation. Generally, stationary objects are preferred, and the vehicle also needs to remain stationary. In short, the reference target should be selected when the vehicle remains stationary.

Step S203: Identify the flooding position in the image frame relative to the reference target.

In this embodiment, the location of flooding is identified through image recognition technology. Specifically, the position of the flooding in the image frame is determined by identifying the color of a continuous piece of the same pixel in the image frame. For example, if you select a wall as the reference target, there will be a continuous piece of white pixels in the image, but the water pixels are not white, and the water pixels are a piece of yellow or gray pixels. There are pixels of two colors in the center, and the pixels of water are generally below. By analyzing the position of the pixels of the water relative to the reference target on the image, the position of the water relative to the wall can be known, which is also the flooding position. In this embodiment, the height of the flooded position can be obtained through conversion according to the ratio of the image frame to the actual object and the ratio formula. For example, through image recognition technology, it is recognized that the 4-meter-high white wall has similar 800 pixels in the direction perpendicular to the ground, and after flooding, 400 pixels in the direction perpendicular to the ground change into other colors. At this time, the water level is expected to reach 2 meters.

Step S204: Judging whether the flooding position has reached the preset position, if yes, skip to step S206, otherwise, skip to step S205.

In this embodiment, the preset position is half of the height of the reference target in the image frame. When the flooding position reaches half of the height of the reference target in the image frame, it is considered that the vehicle is in a dangerous state of flooding.

Further, the method also includes:

Step S205: Determine whether the change of the flood position exceeds a preset change value within a preset time, if yes, go to step S206, otherwise go to step S205.

In this embodiment, it is also possible to judge whether the vehicle is in a dangerous state of flooding by judging the change of the flooding position. For example, take the wall as a reference target, set the preset time to 40 seconds, and identify whether the change of the flood position within 40 seconds exceeds one-third of the wall height. If it is recognized that the flooding position changes by more than one-third of the wall height within 40 seconds, it is considered that the flooding position is rising sharply, and the vehicle is in a dangerous state of flooding.

That is to say, as long as the flooding position exceeds the preset position of the reference target or the change value of the flooding position exceeds the preset value within the set time, the vehicle is considered to be in a dangerous state of flooding.

Step S206: When the vehicle is considered to be in a dangerous state of flooding, a flooding warning signal is sent to notify the user.

In this embodiment, the flood warning signal is sent to the user's mobile terminal through the 2G/3G/4G network.

Further, after the step of judging that the vehicle is in a dangerous state of flooding, the method further includes:

Step S207: Obtain the image screen inside the vehicle, determine whether there is a person inside the vehicle, and if there is a person in the vehicle, send a distress signal and notify the preset relevant personnel.

In this embodiment, the preset relevant personnel may be rescue personnel from institutions such as public security, firefighting, and hospitals. The distress signal and the early warning signal are different. The distress signal is mainly aimed at sending a distress signal to rescuers when the vehicle is flooded and people are trapped in the vehicle. The distress signal is mainly sent through the 2G/3G/4G communication module, or through the broadcasting method of the base station.

In this embodiment, the warning level can be set according to the height of the flood position relative to the reference target. For example, set when the flooding position is relative to the reference target, when it is at the first position of the reference target, the first level of flood warning will be performed; when the flooding position is relative to the reference target, when it is at the second position of the reference target, the second level will be performed Flooding warning; set when the flooding position is relative to the reference target and is at the third position of the reference target, the third level of flooding warning will be performed. Wherein, the first position is one-half of the reference target, the second position is two-thirds of the reference target, and the third position is three-quarters of the reference target. The first level of flooding warning is mild flooding warning, the second level of flooding warning is moderate flooding warning, and the third level of flooding warning is severe flooding warning.

Further, the method further includes: Step S208: controlling the opening of preset doors and windows in the car for the user to escape.

In this embodiment, when it is recognized that the vehicle is flooded and a person is trapped in the vehicle, the preset doors and windows in the vehicle are controlled to open to help the user escape. For example, control the opening of the sunroof of the vehicle so that the user can escape from the top.

The working principle of the present invention will be described below with reference to FIG. 1 and FIG. 2 .

An image frame of a set position outside the vehicle is acquired, and a reference target in the image frame is determined. For example, take the vertical pillar in the image frame as the reference target. Identify the location of flooding relative to upright columns in the image frame. Judging the position of the flooding position relative to the reference target, when it is recognized that the flooding position reaches 1/2 of the height of the reference target in the image frame, that is, when the water soaks through 1/2 of the upright column, Issue a mild flood warning; when it is recognized that the flood position reaches two-thirds of the height of the reference target in the image frame, that is, when the water soaks through two-thirds of the upright column, a moderate flood warning is issued. Water immersion warning; when it is recognized that the water immersion position reaches three-quarters of the height of the reference target in the image frame, that is, when the water has penetrated three-quarters of the upright column, a severe flooding warning is issued.

When a mild flooding warning signal is issued, the image screen of the vehicle is obtained to determine whether there is a person in the vehicle. If it is determined that there is a person in the vehicle, a distress signal is sent to notify the rescue personnel of public security, fire protection, hospitals and other relevant institutions.
