Geometric distortion test also called grid distortion test chart, which is used for test the distortion of the photo or the line of camera. This chart can be detected by naked eyes, we can also use a software to test the distortion value.
Brief Introduction:
Distortion test chart a grid structure which was made by 14 horizontal lines and 19 vertical lines. This grid structure is some as the grid of test builder and this grid structure is corresponding to orbicular structure of T01 geometry test card.
TE183 distortion test chart is designed for testing TV camera’s control and modulate function. We can used the grid structure to do a simple visual assessment for linear scanning, those lines can adjust the location of the camera. And those lines also can be made with black and white lines.
