可以实时完成焦平面信号的数据采集、数据重排、非均匀性校正、图像增强、疵点自动查找和补偿以及视频合成显示等一系列功能。
To decrease the relative errors, the pixel transform method was adopted to recover the geometrical feature of sphere fruit surface from projected image while the area of defect was calculated.
采用像素点变换法，实现了根据三维物体的二维投影图像恢复物体表面的真实几何面积的设想，大大降低了缺陷面积计算的误差；
