In addition, each component can be manufactured separately and assembled together for use, so that the production efficiency of the camera calibration device is improved, and the camera calibration device is convenient for later maintenance.

Specifically, the docking assembly 11 is used for feeding, that is, the sample to be measured is placed on the docking assembly 11 to complete the whole automatic calibration process, and the docking assembly 11 can be fed in a manual or automatic feeding manner. When the automatic feeding mode is adopted, the camera calibration device can be directly applied to a production line for producing and manufacturing samples to be tested, the connection assembly 11 is connected to the output port of the material receiving equipment, and the first discharging assembly 15 is connected to the inlet of the material receiving equipment, so that manual feeding and discharging are not needed, labor is saved, cost is saved, and production and manufacturing efficiency of the samples to be tested is improved.

Through the arrangement, the luminous calibration plate 32 can be moved in the three-dimensional space by driving the XY-axis sliding table 33 and the arc-shaped sliding table 34, so that multiple groups of calibration images with different angles and postures are shot by the camera, more proper image data can be conveniently acquired, and the test parameters obtained after the calibration of the camera of the sample to be tested are more accurate.

It should be noted that, because the transmission direction of the sample to be measured is fixed as the first direction, and the sample to be measured does not move in the direction perpendicular to the first direction, in the embodiment of the utility model, only the XY-axis sliding table 33 is required to adjust the displacement of the light-emitting calibration plate 32 in the first direction, so that the position correspondence of the camera of the sample to be measured and the light-emitting calibration plate 32 is ensured, an accurate calibration image can be shot, and the more accurate test parameters obtained after the calibration of the camera of the sample to be measured are facilitated.
