面阵CCD摄像机物镜光轴与传感器交点坐标的检测

The Coordinate Measurment of Crossing Point Between the Optical Axis of Area CCD Camera Lens and Sensor

本文以面阵CCD摄像机XC-77CE为例,介绍了其物镜光轴与CCD传感器交点坐标的检测方法。由于将视频信号相邻两场合为一帧处理,使测试分辨率与CCD传感器本身的分辨率相当,水平方向上精度可达±1.5个象素,垂直方向上为±0.5个象素。

This paper introduces a coordinate measurment method of cros- sing point between the optical axis of its lens and CCD sensor using a XC-77CE CCD camera as an example. Beacuse the two fields in ve- dieo signals are processed in frame, the measurement resolution is equal to that of the CCD sensor. Horizontal measurment accuracy is ±1.5 elements and vertical is ±0.5 elements.
