Description

Technical Field

[0001] The invention relates to the field of camera testing, and in particular to a collimator bracket. Background Art

[0002] Collimators are standard parts that are widely used in the camera production and testing industry. By adjusting the positional relationship of the prism, light source, and chart, simulations of different object distances can be achieved to meet the requirements of different test distances of the camera. When testing the camera, a huge chart can be fitted through the combination of multiple collimators to meet various test requirements. However, due to the different image ratios of the cameras to be tested (commonly 16:9 and 4:3) and the differences in FOV itself, coupled with the influence of the application scenario, the test requirements for different cameras are similar, but there will be some differences in the layout of the collimators. This requires that the collimator bracket can adjust the distribution position and setting angle of the collimator while ensuring that the physical working distance of the collimator remains unchanged. However, the collimator bracket in the prior art has poor versatility and cannot be adjusted for cameras of different ratios and FOVs. Summary of the invention
