INSTRUCTIONS: TECHNICAL FIELD OF THE INVENTION The present invention relates to an image optical positioning system, and more particularly to an image optical positioning system that utilizes detection of light of a particular wavelength for positioning.

Conventional image optical positioning devices can meet the commercial technical requirements unless they work in a completely dense, controllable light source, and there are still many applications. Moreover, this conflicts with human habits, because human beings can't work normally in a completely dark environment. The reason why there are such troubles is that the 'off-scission light source location is susceptible to environmental light interference, and the anti-noise ability is extremely low. To.

[Embodiment] Please refer to Fig. 1 and Fig. 1 is a functional block diagram of an image optical positioning system 1 of the present invention. System 10 includes an optical transmitter 20 and a processing module 40. The optical transmitter 20 includes a wireless receiver 22 and a light source 24, which can be regarded as a terminal to be tested, and is used to be mounted on the tower 1 1355481. No secret (4) 22 wires receive the signal in a wireless manner, and the light source 24 is used to generate a light according to the light source control signal. The processing module 々 ο can be regarded as a host end, which includes an optical sensor 42 , an optical analysis unit 44 , a wireless transmitter 46 , a light source offset calibration unit 48 , a light source positioning unit 50 , a command query unit 52 and a function execution unit 54. The optical sensor 42 is used to sense the light intensity of the surrounding environment. The optical analysis military system is used to generate a control signal based on the light intensity of the optical filament 42. The wireless transmitter _ 46 is used to wirelessly transmit the light source control signal. The light source offset calibration unit # is used to generate a command according to the shape formed by the light of the predetermined wavelength range by the --wave-wave wire locating unit 5Q system. The command query unit 52 is configured to store a plurality of commands 'each-command corresponding to the shape formed by the light of the predetermined wavelength range determined by the light source positioning unit 50. The function execution unit % is used to perform the corresponding function according to the command. In the embodiment, the processing module 40 can be a desktop computer, a notebook computer, a worker's brain or a digital personal assistant, etc., and the optical transmitter 20 can be disposed on the user's body or other objects to be tested. The device of _ will be described in detail below. Please - and refer to 1 @ and 2 ® 1 2 _ the method flow chart of the present invention. In the beginning, the optical sensor 42 senses the intensity of the ambient light. In a preferred embodiment, the optical sensor may be a charge-and-light device (10) ton (10) 叩 (four) heart '(10) ^ or a complementary metal oxide semiconductor (CMOS) optical sensor for sensing the periphery The light intensity of the environment (step 2〇2) to determine the wavelength distribution or 疋 brightness distribution of the current ambient light source. Then, the optical analysis unit 44 selects a predetermined wavelength range of light according to the sensed wavelength distribution or the luminance distribution, and generates a light source control signal accordingly (step 2〇4). And 8 1355481 sends the light source control signal through the wireless (4) 46 gamma scale (sand: Bluetooth transmission, Zigbee transmission specification or 802.11 series wireless network transmission specification) (step 2〇6). When the wireless receiver 22 of the optical transmitter 20 receives the light source control signal, it controls the light source 24 to generate light of the predetermined wavelength range according to the content of the light source control signal (step 2〇8). Next, although the predetermined wavelength range light (ie, the positioning light source) emitted by the light source 24 appears in the image frame of the optical sensor 42 together with the environmental background, the light source offset calibration unit 48 will sew from the optical money stomach 42. The light from Φ is measured by the alkali to find the position of the optical emitter 20 (step 21). Since the range of the light source that can be sensed by the human eye is limited, the light in the wavelength range that the human eye can sense is visible light, and the wavelength range that cannot be sensed is called invisible light. Light sources in nature are widely distributed, including visible and invisible light of various wavelengths, and thus there are several embodiments of the design of optical analysis unit 44 and light source 24. In the first embodiment, the optical analysis unit 44 is based on the wavelength of the light source, because the noise of the invisible light in the indoor environment is small and does not cause trouble to the human eye, so when the optical sensor 42 detects After the wavelength distribution range of the invisible light in the indoor environment, the invisible light of a predetermined wavelength range is determined as the wavelength value of the light source 24 of the optical emitter 2 to emit the positioning light source. Therefore, the invisible light of the predetermined wavelength range should be selected to be away from the wavelength of the light source having the ambient light wavelength distribution already existing, such as infrared light. In short, it is to find a set of ambient light wavelengths that are different from the existing ones. In the second embodiment, the light source 24 is a dynamic light source and emits a visible light. That is to say, after receiving the preset wavelength range set by the light source control signal, the light source 24 dynamically emits light of different wavelengths (for example, the light source has a plurality of light emitting diodes, every 5 seconds period 9 1355481 Singly emit blue light, red light, green light, or emit a flash light source per unit time (for example, within 5 seconds _ off as a positioning wire... the noise caused by the ambient light source) There is no regular 'even the artificial noise generated by other devices, the possibility of the existence of the same law is also the frequency of the frequency. The source of the source shifts the 48-year-old Wei Weiwei Μ Μ Μ Μ 预设 预设 , , , The position of the optical transmitter 2 is measured. In the third embodiment, since the brightness commonly used in image processing is defined as a step, the optical analysis unit 44 can also generate a light source control signal of a predetermined wavelength range via the wireless transmitter. Shame and wireless connection (4) 22 are sent to the light source Μ, and the light source offset calibration unit can be based on the brightness formula Η = 0.33 * R + 〇 · 56 * (4). 丨丨 * B takes care of the light of the predetermined wavelength of the fine wavelength. Example The positioning light source settings can be applied independently or in combination with each other. The source wavelength sightseeing line (10) and the environment background of the light source 24 appear together in the image screen of the optical sensor 42, but for the system of the present invention. In addition to the information of the preset wavelength range of light, the information of the light is unnecessary, so the purpose of the vehicle's partial miscellaneous unit correction is to illuminate the surface light according to the inspection light 42. (4) The location of 2Q. The silk offset calibration unit will remove most of the unwanted information in a filtered manner, but there will still be residuals and noise. Therefore, the source offset calibration unit 48 also adds a de-weiding component, such as the size of the location information in the image, the number of possible relative distances, the variation of the positioning system, etc., depending on the application. List the conditions for each noise removal. If the environment _ 规 蚊 蚊 彡 彡 彡 A A , , , , , , , , , 135 135 135 135 135 135 135 135 135 135 135 135 135 135 135 135 135 135 135 135 135 135 135 135 135 135 135 135 135 135 135 135 135 135 When the (8) lamp is turned on (off), the light source offset calibration unit 48 will reduce the occurrence of the material as no axis, and then divide the (four) environment and determine the new source wavelength range, and continue to detect the user's next The action light source locating unit 50 is capable of determining the action posture of the user by using the relative position between the light sources by cutting the position of each other. There is a way for φ to calculate the relative position between the light sources by the light source locating unit 50, which is known to those familiar with computer vision (Comp gamma Vi-) _ domain, and will not be described again. Therefore, various algorithms of the optical position unit 5, that is, computer vision, calculate the current action of the user. After the user's action posture is known, the command query unit 52 can look up the table to know a plurality of predefined commands (steps), each of which corresponds to the preset determined by the light source positioning unit %. The shape of the wavelength shouted by the silk. The plurality of commands can be preset or can be freely adjusted by the user. If the user's action is calculated, but the command corresponding to the action cannot be called by the lookup table, there are two possibilities. First, the user does invalid, inaccurate or undefined. - It is Weitong's miscellaneous news, which makes the positioning light source unrecognizable. The above two possibilities, regardless of the type, are always considered as "invalid actions" of the user and are ignored. Because the lying light source is an infinite back S that is continuously executed by the secret ship, if the user cannot perform the action of the gamma (four), the user only needs to repeat the input action again. Finally, the function execution unit 54 can execute the various process processes in accordance with the command upon receiving the command (step 214). 11 1355481 In addition, the optical sensor 42 of the present invention may include more than one charge stealing device or a CMOS optical sensor. When the optical sensor 42 includes only a single-charge coupling device or a CMOS optical sensor, the optical clamping unit 5() can only determine the displacement of the light emitted by the light source in a two-dimensional space. The syllabus (4) contains more than two charge or (10)S optical sensors, and the woven material 5G can determine the displacement of the light emitted by the light source in three-dimensional space - so - she changes in two-dimensional space Positioning the vehicles _ to the position (or shape) in the three-dimensional space changes more, coupled with the design flexibility of the command query unit & Compared with the prior art, the image optical positioning system of the present invention can improve the anti-noise capability of the positioning light source', so that the application threshold of the image positioning technology is reduced, as long as it is in a general indoor environment such as a home, an office, a warehouse, an indoor entertainment place, etc. It can be applied to increase the commercial value of optical positioning of images. In view of the above, the preferred embodiments of the present invention are disclosed above, and are not intended to limit the scope of the invention, and various modifications may be made without departing from the spirit and scope of the invention. The scope of protection of the present invention is defined by the scope of the appended claims.
