Introduction to Chessboard Distortion Test Card

Chessboard distortion test card is used to check the geometric distortion and resolution of cameras

The T06 test chart is designed for checking geometry and resolution.

Chessboard distortion test card parameters

The test card is similar to a chessboard surrounded by 13 × 18 black and white square areas and rectangular areas at the edges corresponding to the grid grating lines of the electronic test generator 14/19. The horizontal grid lines of the entire graphics generator are divided into 42 rows.

Similar to a chessboard the test charts is composed of 13 x 18 black and white square fields which are surrounded by rectangular fields at the edges that correspond to the 14/19 grid raster lines of electronic test generators. (The division of the horizontal grid lines of these generators corresponds to 42 lines per complete picture.)

Use of Chessboard Distortion Test Card

·Check the consistency between geometric shape and grating, and if necessary, use an electronic grid generation device.
·Checking geometry and the congruency of raster, by means of an electronically generated grid, if necessary

·Check the uniformity of signal generation.
