The device will be described in detail below. See Figure 1 and Figure 2 for details. Figure 2 is a flow chart of the method 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 42 can be used as a charging device (charge c〇Upiing dev|ce, CCD) or a complementary metal oxide semiconductor (CMOS) optical sensor.

Since the range of light sources that can be sensed by the human eye is limited, the range of wavelengths that can be sensed by the human eye (10) is light, and there is no __boss_林 visible. The source of light in the secret is very wide, including various There are several embodiments of the design of optical analysis unit 44 and source % for wavelengths of visible and invisible light. 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 is less in the indoor environment, and the human eye is not disturbed by the human eye, and the virtual optical instrument 42 _(four) Wei After the wavelength distribution range of the invisible light, 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 the second embodiment, the light source 24 is a dynamic light source and it emits visible light.

The above three kinds of real-fixed positioning wire settings can be read by themselves, and they are used when they are used together. The pre-3 wavelength range ray (ie, the locating source) emitted by the light source 24 appears in the image frame of the optical sensor 42 along with the environmental background, but for the system of the present invention, except for the preset wavelength range The purpose of the light source shifting fresh unit φ is to determine the position of the optical emitter 20 according to the spectrum induced from the optical filament 42 in the predetermined wavelength range. . The source offset calibration unit 48 will be removed in a wave mode.卩& unwanted information, but still there will be residual noise left. Therefore, the source offset calibration sheet 7G 48 will also add noise removal conditions, such as the size, number, possible relative distance range of the positioning light source displayed in the image, the variation law of the dynamic positioning light source, etc., depending on the application. Add the conditions for each noise removal. If the noise source of the % environment has a great influence on the positioning light source, the deviation value of the positioning light source exceeds 200940954 'The mosquitoes _ poor shooting range _ can not be located, which means that (four) Wei appeared in the short time non-original expectations The change of the light source, such as the open (8) lamp, the open (10) window, etc., the light source bias frequency unit 48 will regard this situation as an invalid action, and then (4) analyze the occupational light source and decide the new light source wavelength range, the succession detection Measure the user's next action. The light source locating unit 5 is configured to determine the action posture of the user by using the relative position between the light sources by turning the relative position of the light source (4). There is a rumor about the way in which the wire positioning unit 5G calculates the wire (4) between the wires. It has been known that the computer vision (_ tender) is understood, and there is no other _. Because of the silk position unit, the computer's current actions are calculated using various algorithms of computer vision. After the user's action posture is known, the command query unit 52 can look up the table to find a plurality of predefined commands (6) mmand) (step plus), and each command corresponds to the light source positioning unit % determined by the wavelength setting. The shape formed by the silk. The plurality of commands can be set or can be freely adjusted by the user. If the user's action is calculated, but the command corresponding to the action cannot be found by the checklist, there are two possibilities. First, the user does invalid, inaccurate or un-domain; - 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 side positioning light source is an infinite loop that has been continuously executed since the system is turned on. If this time cannot be correct to the user's action, 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 200940954 In addition, the optical sensor of the present invention may include more than one charge surface sealing device or a surface optical sensor. When the optical sensor 42 contains only a single charge-consuming device or a CMOS light, the displacement of the light in a two-dimensional space is carried out. When the learning sensor 42 includes an optical contact device on the sample, and the optical sensor is compared to the c, the light source positioning unit 50 can determine the displacement of the light emitted by the light source in a three-dimensional space, so that 'compared to in two dimensions The change of the space, the relative position (or shape) of the positioning light in this case changes more in the three-dimensional space, and the design flexibility of the command stored in the command query unit η is increased. Compared with the prior art, the image optical positioning system of the invention can improve the anti-noise ability of the positioning light source, and the image positioning technology can reduce the limit of shooting, as long as the indoor environment such as home, office, warehouse, indoor entertainment Locations and the like 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 invention to those skilled in the art, 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 therefore defined by the scope of the appended claims.
