幾何/重合測試卡簡介

　　幾何/重合測試卡在條紋背景上有水平23個和垂直53個直線柵格。3個網格線從中間劃分外圍的3行網格。分辨率測試卡網格線的寬度是圖像寬度的0.15%。大圓形線的直徑為83是圖像高度的1/3%，5個小圓形線的直徑是圖像高度的25%。

　　4分辨率鍥被分布在大圓的0°、45°、90°和135°處，對應的2-10MHz信號頻率(8 MHz和600線的標記結束)。

　　幾何/重合測試卡應用

　　分辨率測試卡該測試卡專門為運營調整和控制TV攝像機而設計。

　　圓圈的線性掃描可以粗略的視覺評估。

　　網格線的作用是調整定位。

　　鍥的作用是測試分辨率。

　　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
