棋盘式畸变测试卡简介
棋盘式畸变测试卡用于检查摄像机的几何失真及分辨率
The T06 test chart is designed for checking geometry and resolution.
棋盘式畸变测试卡参数
测试卡类似于一个由13×18的黑色和白色正方形区域以及由矩形区域在对应于电子测试生成器14/19网格光栅线边缘所包围的棋盘。（整个图卡发生器的水平网格线被划分为相应于42行）。
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.)
棋盘式畸变测试卡使用
·检查几何形状和光栅的一致性，如果有必要用电子生成网格的装置。
·Checking geometry and the congruency of raster, by means of an electronically generated grid, if necessary
·检查信号生成的均匀性。
·Checking the uniformity of the signal generation
