產品簡介

SFRplus汽車測試圖卡魚眼測試圖卡預失真測試卡，大多數汽車相機模塊具有顯著魚眼失真功能可以檢測難以看見的外部像場。這個測試圖卡具有測量針插預失真大約的汽車照相機模塊的桶扭曲補償。

詳細介紹

SFRplus汽車測試圖卡魚眼測試圖卡預失真測試卡

預失真：大多數汽車相機模塊具有顯著魚眼失真功能可以檢測難以看見的外部像場。這個測試圖卡具有測量針插預失真大約的汽車照相機模塊的桶扭曲補償。

方形網格：5×7的斜方形網格

基材油墨類型：磨砂紙和油墨減少反射光。這是高水平的失真測量至關重要，否則鏡面反射可以毀掉MTF測量。

測量

對比度：10:1的對比度，這是常見幾種汽車測試標準之一。

彩色圖卡：20塊顏色圖對顏色的準確性和拜爾過濾器的位置進行測量。

活動區域：超大圖用于超過24MP的傳感器。此圖的活動區域為36x50英寸，打印紙張為44x60英寸。

Options include:

Pre-distortion: Most automotive camera modules have significant fisheye distortion which can make it difficult to the outside of the image field. this chart has pincussion pre-distortion to approximay compensate for the barrel distiortion of the automotive camera module. The distortion coefficients that should be entered into the Imatest SFRplus settings window are [1.167 1.577]

Square Grid: 5x7 slanted square grid

Substrate & ink type: Matte paper & ink can be used to reduce reflected light. This is critical for high levels of distiortion, otherwise specular reflections can ruin MTF measurements

Contrast levels: 10:1 contrast ratio, common for several automative testing standards

Color chart: a 20 patch color chart for color accuracy and bayer filter position verification

Bar to Bar height: the maximum bar to bar height is 38.5 inches on the left and right side. The minimum bar to bar height is 23.5 inches in the center.

Active Area: the extra-large chart be used for sensor sizes above 24 MP. This chart has an active area of 36 x 50 inches and is printed on 44 X 60 inch paper

The active area of the chart includes white space above and below the top and bottom distortion bars. It is slightly larger than the printed area, which is bounded by the distortion bars on top and bottom. White space is included in active area because test images of the chart must include this white space in order to enable automated processing in SFRplus software.
