Description

Technical Field

[0001] This utility model belongs to the field of facial recognition technology, specifically relating to a testing system based on facial recognition. Background Technology

[0002] Facial recognition is a biometric technology that identifies individuals based on their facial features. It involves using cameras or webcams to capture images or video streams containing faces, automatically detecting and tracking faces within the images, and then performing facial recognition on the detected faces. This technology is also commonly referred to as image recognition or face identification.

[0003] In recent years, with the in-depth research and development of artificial intelligence vehicles and the rapid development of deep learning technology, facial recognition technology has been greatly promoted, and its application in automobiles has become increasingly widespread.

[0004] Conventional phone holders are not suitable for fixing phones on microscopes, which can lead to more problems due to incompatibility between the phone holder and the device, thus increasing the workload of the staff.

[0005] Chinese Patent Publication No. CN115422058A discloses a method and apparatus for testing facial recognition applications, relating to the field of computer technology. One specific embodiment of the method includes: in response to receiving test task data and test data, saving the test data to a designated location; operating the facial recognition application according to the test task data, causing the facial recognition application to invoke a modified camera service to acquire test data from the designated location; and using the acquired test data to test the facial recognition application. This embodiment saves testing costs and improves testing efficiency. Furthermore, by using uniform test data, the test results are more accurate, avoiding inaccurate results caused by differences in lighting angles and other factors when multiple test data are collected.

[0006] However, the above methods involve multiple testing dimensions and require significant investment. For simple, routine tests, this approach is like using a pearl to catch a pebble, wasting human and financial resources. Yet, for simple, routine face tests, directly using photographs does not yield specific and accurate test values. Utility Model Content

Detailed Implementation

[0026] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments. Example

[0027] like Figure 1-7 As shown, a face recognition-based testing system consists of a photo display screen 1 and a moving structure 2, wherein the photo display screen 1 and the moving structure 2 are connected by a bracket 3, and the bracket 3 is detachable from the photo display screen 1 and the moving structure 2.

[0028] like Figure 1-2As shown, the movable structure 2 consists of a slide rail 201 and a slider 202. The upper surface of the slider 202 has five openings: four small openings and one large opening. The four small openings are located at the four corners of the slider 202, and the large opening is located in the middle of the slider 202. Both ends of the slide rail 201 are equipped with floor support feet 2011, but one end also has a moving wheel 2012. Figure 5-7 As shown, the ground support foot 2011 is divided into an upper section 2011A and a lower section 2011B. The inner diameter of the upper section 2011A is larger than that of the lower section 2011B. When the upper section 2011A and the lower section 2011B are extended, the height of the ground support foot 2011 is greater than the height of the moving wheel 2012, thereby suspending the moving wheel 2012 and fixing the position of the slide rail. When the upper section 2011A and the lower section 2011B are shortened, the height of the ground support foot 2011 is less than the height of the moving wheel 2012. At this time, the moving wheel 2012 touches the ground, which facilitates the movement of the slide rail 201.

[0029] A connecting rod 203 is provided in the middle of the slide rail 201 to fix the position of the two slide rails 201, such as... Figure 3-4 As shown, a connecting plate 204 is provided between the two sliders 202. The connecting plate 204 has a circular through hole in the middle, and an internal thread is provided in the circular through hole. A screw 205 passes through the circular through hole and is connected to the connecting plate 204 by the thread. A motor 206 is connected to the screw 205. A motor support 207 is connected to the lower side of the motor 206. The two sides of the motor support 207 are fixedly connected to the slide rail 201. When the motor 206 is running, the screw 205 rotates, which causes the connecting plate 204 to rotate in the opposite direction. However, under the action of the two sliders 202, the connecting plate 204 cannot rotate, which causes the two sliders 202 to move, which in turn drives the structure on the sliders 202 to move. Again, the motor 206 here is a bidirectional rotating motor, which enables the sliders to move back and forth.

[0030] An electronic ruler 4 is provided on the front side of the slider 202. As the slider 202 moves, the electronic ruler will also read the distance that the slider 202 has moved and mark it. This data is collected in order to accurately test how far away from the car's face recognition can be cracked.

[0031] The lower section 2011B has a support foot 2011G on its lower side. The upper section 2011A inside the ground support foot 2011 is hollow, and the lower section 2011B is hollow. Both sides of the upper section 2011A have circular openings 2011C of the same diameter. The upper half of the lower section 2011B has a through hole 2011D, and a spring 2011E and a retaining post 2011 are installed inside the through hole 2011D. F, wherein the two ends of the spring 2011E are respectively connected to the locking post 2011F, and the middle of the spring 2011E is fixed in the through hole 2011D, so that the spring is not moved in the through hole 2011D, but the locking posts 2011F on both sides will move. When the locking post 2011F moves to the circular opening 2011C of the upper section 2011A, under the action of the elastic potential energy of the spring, the locking post 2011F pushes out of the circular opening 2011C and locks the upper section 2011A and the lower section 2011B.

[0032] like Figure 3 As shown, the bracket 3 consists of a bracket fixing foot 301 and a display screen fixing frame 302. The bracket fixing foot 301 consists of four auxiliary support feet 3011 and a fixing plane 3012. The four auxiliary support feet 3011 correspond to the four small openings on the upper surface of the slider 202, so that the four auxiliary support feet 3011 can be inserted into the four small openings to ensure the stability of the support bracket. The top surface of the four auxiliary support feet 3011 is fixedly connected to the fixing plane 3012. A through circular hole 3013 is provided on the fixing plane 3012, which corresponds to the large opening on the upper surface of the slider 202.

[0033] The display screen mounting bracket 302 consists of a column 3021 and a telescopic column 3025. The column 3021 is hollow from 400mm above the bottom surface, and the telescopic column 3025 is installed inside. The telescopic column 3025 is telescopically connected to the column 3021. Both the telescopic column 3025 and the column 3021 have square openings 3026 on their sides. The square openings 3026 have moving rails 3027, which are double-rail structures. One rail is used for the installation of the photo display screen 1, and the other rail has a back plate 3024. The back plate 3024 is provided to prevent the photo display screen 1 from falling.

[0034] The top surface of the telescopic column 3025 is provided with an extension plate 3028, and a cylinder 3029 is provided under the extension plate 3028. The base of the cylinder 3029 is fixed on the fixed plane 3012. The distance between the column 3021 and the telescopic column 3025 is changed by the retraction of the flagpole of the cylinder 3029, so that the bracket can be adapted to various displays and increase the applicability of the system.

[0035] In practice:

[0036] In use, first remove the back plate 3024, place the photo display screen 1 into the moving rail 3027, then adjust the cylinder 3029 so that the upper and lower moving rails 3029 fix the photo display screen 1, display the required photo on the photo display screen 1, and start the motor 206 to make the screw 205 rotate, and then move the slider 202 through the connecting plate 204. At the same time, the electronic ruler 4 records the movement record, and at the same time, the staff records the recognition time and recognition result of the vehicle face recognition system.

[0037] Specific effects of the embodiment:

[0038] This embodiment uses a slide rail and slider to test the recognition distance of a person to the face recognition system, and the electronic ruler can mark the precise distance, providing strong data support for the improvement of face recognition. The motor drive provides support for the recognition distance test. In this embodiment, a telescopic bracket is used to make the bracket adaptable to various displays, and the four pillars on the legs enhance the stability of the overall structure.
