几何/重合测试卡简介

　　几何/重合测试卡在条纹背景上有水平23个和垂直53个直线栅格。3个网格线从中间划分外围的3行网格。分辨率测试卡网格线的宽度是图像宽度的0.15%。大圆形线的直径为83是图像高度的1/3%，5个小圆形线的直径是图像高度的25%。

　　4分辨率锲被分布在大圆的0°、45°、90°和135°处，对应的2-10MHz信号频率(8 MHz和600线的标记结束)。

　　几何/重合测试卡应用

　　分辨率测试卡该测试卡专门为运营调整和控制TV摄像机而设计。

　　圆圈的线性扫描可以粗略的视觉评估。

　　网格线的作用是调整定位。

　　锲的作用是测试分辨率。

　　Resolution test card Introduction to geometric / coincidence test cards

　　Geometric / coincidence test card has a horizontal 23 horizontal and vertical 53 grid on a stripe background. 3 grid lines from the middle of the three-row grid. The width of the grid line is 0.15% of the image width. The diameter of the large circular line is 83% of the height of the image, and the diameter of the five small circles is 25% of the image height.

　　4 resolution resolution is distributed at 0 °, 45 °, 90 ° and 135 ° of the large circle, corresponding to the 2-10 MHz signal frequency (8 MHz and 600 line mark ends).

　　Geometric / coincidence test card application

　　The test card is designed specifically for operational adjustment and control of the TV camera.

　  The linear scan of the circle can be roughly visualized.

　　The role of the grid line is to adjust the positioning.

　　The role of perseverance is to test the resolution.Resolution test card
