    Abstract: A fixing structure includes a first supporting disc, a second supporting disc, and an electronic connector. The first supporting disc defines a first through hole. The second supporting disc is movably connected to the first supporting disc. The second supporting disc defines a first receiving groove for receiving a voice coil motor having a lens. The second supporting disc further defines a second through hole passing through a bottom of the first receiving groove. The first through hole and the second through hole are coaxial. The electronic connector is disposed on the second supporting disc, and can be electrically connected to the voice coil motor and an external power supply.

    Abstract: A calibration device includes a base, a support column coupled to the base and extending in a first direction, and a crossbar coupled to the support column. The crossbar includes a positioning base and a carrier. The positioning base is fixed to the support column. The carrier is coupled to the positioning base and rotatable about a second direction perpendicular to the first direction. The carrier includes a distance sensor and a calibration platform. The calibration platform mounts a depth camera. The carrier is configured to rotate about the second direction to rotate an optical axis of the depth camera in a first calibration plane defined by the first direction and a third direction. The third direction is perpendicular to the first direction and the second direction.

    Abstract: A method of inspecting and controlling applied to a process of a testing a camera for correct color temperature in image-capturing includes: obtaining a first device identifier of light sources; obtaining a second device identifier of control devices; wherein each control device governs the opening or closing of a light source; associating the first device identifiers with each second device identifier, and generating a binding list; obtaining the second device identifier corresponding to a camera device; comparing the second device identifier corresponding to the camera device with the binding list, and recording the corresponding first device identifiers; wherein the camera device takes pictures under the light source corresponding to the first device identifiers to obtain image for analysis and analyzing whether image-capturing function of the camera is normal. A computer device and a storage medium for performing the above-described method are also disclosed.

    Abstract: An automatic leveling system includes a platform, a leveling device provided on the platform, a loading tray provided on the leveling device, three reflecting devices provided on the loading tray, an image acquisition device provided above the loading tray, a height positioning device provided on an end of the image acquisition device facing the loading tray, a light source configured to emit light, and a controller coupled to the image acquisition device. The height positioning device processes light emitted by the light source into three paths of light to the three reflecting devices. The three reflecting devices reflect the three paths of light. The image acquisition device acquires the three paths of reflected light into a light signal. The controller detects deflection values of the loading tray according to the light signal and controls the leveling device to level the loading tray.

    Abstract: An illumination device includes a box body, a LED module, and a light homogenizing plate. A variety of different color temperatures are set in different chips controlling the LEDs in the LED module. The homogenizing plate converts light, such that the illumination device can generate light beams of various color temperatures. The test requirements applicable to different lenses or in relation to different color temperatures of the same lens at different periods can thus be met.
