1 . Lateral operation rate: The data is the best resolution obtained by the USAF1951 operation rate test card in the full range of the camera panoramic depth and full field of view.

2. Z-direction repetition accuracy (1σ):

(1) The data is tested in the camera's panoramic depth and full depth of vision;

(2) The following test method was adopted: Shot the field point calibration board at the edge of near-depth of field, focal plane and distant deep edge, and divided the FOV into 9 areas (the area of dots within the area was 1.4%FOV) at each location. The double standard deviation of 100 measurements of the B mean difference between the upper and lower calibration boards in the 27 areas was calculated, and the worst value was taken as the final result.

3 .Full-cycle frame rate: real-time shooting, calculating and saving multi-view and depth information frame rate (recommended graphics card configuration RTX3080Ti or above)
