摘要:
为实现对彩色摄像机颜色分辨力测试,设计了通过双离散颜色源、反射式准直光学系统和四杆靶靶标模块组成的测试装置。双离散颜色源分别产生经过标定的前景和背景颜色光束,经过准直光学系统,最终合成四杆靶测试靶标图像。该系统在测量过程分别获取各频率下从靶标图像中提取的目标靶标并对其进行色差计算,通过图像算法对测试靶标进行判断和识别,获得彩色摄像机的最小可分辨色差(minimum resolvable E difference,MRED)和最小可探测色差(minimum detectable E difference,MDED),实现对彩色摄像机颜色分辨力的客观检测。
Abstract:
In order to calibrate the color resolution of a color camera, an experimental prototype is designed which consists of a double discrete color source, a reflective collimating optical system and four-bar target panel. The dual discrete color sources respectively produce a foreground and background color beam passing through a collimating optical system, and then form a four-bar synthetic image on the color CCD. In the experiment, we extracts the stripe from the target image at each frequency and calculates the color difference of each pixel. Then, we use the criterion to mark the detectable pixels and define the minimum resolvable E difference (MRED) and the minimum detectable E difference (MDED) as two indexes to objectively evaluate the color resolution of the color camera.
