DETAILED DESCRIPTION

[0024] The embodiment of the present invention discloses a rotating light source system for camera testing and calibration, such as Figure 1-6 As shown, including:

[0025] A base plate 1, with two support frames 2 fixedly mounted on the top of the base plate 1;

[0026] Pads 18 are fixedly connected to the inside of both ends of the substrate 1, and the bearing capacity of both ends of the substrate 1 can be enhanced by the pads 18. Two sets of supporting legs 15 are fixedly connected to the bottom end of the substrate 1, and the supporting legs 15 play a certain role of supporting and balancing the substrate 1. At the same time, the pads 18 can enhance the bearing strength of the supporting legs 15 on the substrate 1;

[0027] The conveyor belt 16 is disposed at the bottom end of the substrate 1 and is located in the middle of the opposite ends of the two sets of support legs 15 and corresponds to the light-transmitting holes 9. A test camera 17 is disposed at the top of the conveyor belt 16;

[0028] An electric diaphragm driver 19 is fixedly installed at the middle of the bottom end of the substrate 1. The electric diaphragm driver 19 can accurately control the size of the central light hole of the electric diaphragm to control the size of the light spot of the light beam passing through the electric diaphragm. A light-transmitting hole 9 is opened in the middle of the substrate 1. The light-transmitting hole 9 corresponds to the light-transmitting hole on the electric diaphragm, and the light-transmitting hole 9 corresponds to the electric diaphragm driver 19.

[0029] A calibration component, the calibration component is arranged on the top of the substrate 1;

[0030] The calibration assembly includes a calibration ring 8, the top of the calibration ring 8 corresponds to the port of the lampshade 6. When the top of the calibration ring 8 and the top of the lampshade 6 fit together, the lampshade 6 can be aligned with the light transmission hole 9 to ensure that the light source is incident in a vertical direction. Both ends of the calibration ring 8 are fixedly connected with a connecting plate 14.

[0031] A rotating light source assembly is arranged at one end opposite to the two support frames 2, and includes a servo motor 3, a reducer 4 is arranged on the back of the servo motor 3, a linkage rod 5 is fixedly connected to the output end of the reducer 4, a plurality of lampshades 6 are fixedly installed on the outside of the linkage rod 5, and a color temperature light source 7 is arranged inside the lampshade 6;

[0032] There are two lifting mechanisms, both of which are arranged at opposite ends of the two support frames 2. The calibration ring 8 can be lifted upward by the lifting mechanism and abutted against the flat part of the edge of the lampshade 6, so that the lampshade 6 is aligned with the light-transmitting hole 9, ensuring that the light source is incident in a vertical direction;

[0033] The lifting mechanism includes a hydraulic cylinder 12 , an output end of the hydraulic cylinder 12 is fixedly connected to a moving plate 13 , and a bottom end of the moving plate 13 is fixedly connected to a top end of a connecting plate 14 .

[0034] The bottom end of the base plate 1 is fixedly mounted with a cylinder 11, and the bottom end of the base plate 1 and the bottom end of the electric aperture driver 19 are provided with a baffle 10, and the bottom end of the baffle 10 is fixedly connected to the output end of the cylinder 11;

[0035] The present invention communicates with a computer via a USB-to-serial communication method. 10 PCS light sources with different color temperatures can arbitrarily switch light sources and change the size of light spots by issuing commands from the computer to meet the testing requirements of various cameras. After the light source is switched, the computer can obtain timely feedback, determine the current light source position, and provide various query commands to query various operating states of the device. 10 PCS light sources are evenly distributed on the disc, which is convenient for reducing installation difficulty, facilitating debugging and accurately controlling the light source position.

[0036] How it works: See Figures 1 to 4 When the test camera 17 needs to be tested and calibrated,

[0037] To implement the first step, the operator first starts the servo motor 3, and then makes the output end of the servo motor 3 drive the reducer 4 to work, and the output end of the reducer 4 drives the linkage rod 5 to rotate, and the linkage rod 5 drives the lampshade 6 outside it to rotate, and then starts the hydraulic cylinder 12, so that the output end of the hydraulic cylinder 12 drives the moving plate 13 and the connecting plate 14 to move, and the moving plate 13 drives the calibration ring 8 to move away from the top end of the base plate 1, until the top end of the calibration ring 8 and the bottom end of the lampshade 6 are in contact with each other and stop;

[0038] Implement the second step of operation, take the test camera 17, and then place the test camera 17 on the upper surface of the conveyor belt 16, and then drive the test camera 17 to move through the conveyor belt 16, so that the test camera 17 moves from one end of the conveyor belt 16 to the other end of the conveyor belt 16;

[0039] In the third step, when the test camera 17 reaches below the light-transmitting hole 9 , the output end of the cylinder 11 drives the baffle 10 to move, so that the light passes through the light-transmitting hole 9 and reaches the position of the photosensitive element of the test camera 17 after passing through the aperture.

[0040] Although the embodiments of the present invention are described with practical solutions, they do not constitute limitations on the meaning of the present invention. For those skilled in the art, it is obvious to modify the implementation scheme and combine it with other solutions based on this description.
