[0024] Example
[0025] See Figure 1-Figure 6 , The present invention provides a suspended face recognition system for retail stores, and its structure includes a face recognition machine 1, a display screen 2, a rectangular box 3, and a housing 4. The face recognition device 1 is located north of the housing 4 upward, The housing 4 is connected to the face recognition machine 1, and the front panel of the housing 4 is provided with a display screen 2. The display screen 2 is connected to the face recognition machine 1 through electrical signals, and the rectangular box 3 There are two, and the rectangular boxes 3 are arranged on both sides of the housing 4 in a symmetrical structure with respect to the housing 4;
[0026] The face recognition machine 1 is composed of a working cavity 101, a light guiding device 102, and a camera 103. The light guiding device 102 and the camera 103 are both installed in the working cavity 101. The light guiding device 102 is provided with two. The light guide device 102 is symmetrically arranged on both sides of the camera 103;
[0027] The light guide device 102 is composed of a main channel 1021, a light inlet channel 1022, a light guide mechanism 1023, an output channel 1024, and an auxiliary mechanism 1025. The light inlet channel 1022 communicates with the main channel 1021, and the light inlet channel 1022 passes through the main channel 1022. The channel 1021 communicates with the output channel 1024, the light guide mechanism 1023 is connected with the main channel 1021, the auxiliary mechanism 1025 is fixedly connected with the output channel 1024, and the auxiliary mechanism 1025 is fixedly installed on the inner wall of the output channel 1024.
[0028] The light guide mechanism 1023 is composed of a rotating rod 10231, a sliding block 10232, a central axis 10233, a guide rod 10234, and a sliding rail 10235. There are two rotating rods 10231, and the rotating rod 10231 has a symmetrical structure with respect to the central axis 10233. The central shaft 10233 is mechanically welded to the rotating rod 10231, the sliding rail 10235 is provided with a guide rod 10234, and the guide rod 10234 is mechanically matched with the sliding block 10232. The sliding block 10232 penetrates the rotating rod 10231. The rotating rod 10231 is mechanically connected to the guide rod 10234 through a sliding block 10232. The sliding block 10232 and the sliding rail 10235 are mechanically slidably fitted. The rotating rod 10231 is provided with a shading plate on one end away from the central axis 10233. The length of the shading plate is slightly Greater than the width of the main channel 1021, the establishment of the guide rod 10234 can make the slider 10232 slide in the slide rail 10235 without offset, and accurately guide the slider 10232 to slide, so as to ensure that the movement track of the rotating rod 10231 does not deviate , Play the role of limit guide.
[0029] The slide rails 10235 are provided with two and are set up in a centrally symmetrical structure with respect to the central axis 10233. The slide rails 10235 are in a ring structure with only a quarter arc length, so that the rotation angle of the rotating rod 10231 is fixed at nine Ten degrees.
[0030] The auxiliary mechanism 1025 is composed of a fixed rod 10251, a solid block 10252, and an auxiliary light guide channel 10253. One end of the fixed rod 10251 is fixed on the inner wall of the output channel 1024, and the other end is fixedly connected to the solid block 10252. The solid block 10252 There is an auxiliary light guide channel 10253, which penetrates through the solid block 10252, and a reflective light plate is provided on the upper inner wall of the auxiliary light guide channel 10253. With the help of the reflective light plate, access to the auxiliary light guide channel 10253 can be increased The luminous flux reflected by the light, which makes the light more abundant.
[0031] The solid block 10252 has an equilateral triangle structure, and the auxiliary light guide channel 10253 penetrates and is embedded on the solid block 10252. The equilateral triangle structure makes the light guide of the auxiliary light guide channel 10253 more stable.
[0032] Originally, the main channel 1021 was in a closed state. When face recognition is required, the central shaft 10233 is driven to rotate with the help of external mechanical force. The central shaft 10233 drives the shading plate connected to it through the rotating rod 10231 to rotate accordingly, so that the shading plate Gradually separate from the main channel 1021. When the rotating rod 10231 rotates ninety degrees, the light shield is completely separated from the main channel 1021. The light entering from the light entrance channel 1022 enters the output channel 1024 through the main channel 1021 and passes through the output channel 1024. After passing out, part of the reflected light enters the auxiliary mechanism 1025. When passing through the auxiliary light guide channel 10253, it is reflected by the reflective light plate on the inner wall of the auxiliary light guide channel 10253, thereby increasing the luminous flux of the output channel 1024 and making the light more sufficient. To solve the problem of unclear recognition image due to insufficient light.
[0033] The problem solved by the present invention is that due to the limitation of the size of the space in the retail store, the face recognition machine may be installed in a backlit or dark place, so that when the face recognition device recognizes a face, the recognition image is not clear due to insufficient light. , And even lead to incorrect recognition. The present invention uses external mechanical force to control the rotation of the rotating rod 10231 through the combination of the above components, and uses the rotating rod 10231 to drive the shading plate to move to realize the separation or connection between the shading plate and the main channel 1021. To achieve the control of opening or closing the main channel 1021, so as to realize the effect of intermittent light supplement; by opening the auxiliary light guide channel 10253 on the inner wall of the output channel 1024, and set up the reflective light plate on the auxiliary light guide channel 10253 to increase the output channel The purpose of 1024 luminous flux makes the supplementary light for face recognition more sufficient.
