光电摄像器用作微型计算机的传感器,对光学图像的光强进行数字化测量,其光电转换特性γ是一个重要参量.γ值不等于1,将会给测量结果造成很大的误差.本文描述了对γ≠1的摄像器进行非线性校正的新方法,并以应用实例作了验证.
Photoelectric camera as a microcomputer sensor, the optical image of the light intensity of digital measurements, the photoelectric conversion characteristics of γ is an important parameter.γ value is not equal to 1, the measurement results will cause a great error.This paper describes the γ ≠ 1 for non-linear correction of the new method of the camera, and the application example has been verified.
