中文摘要：

介绍了飞行时间法的测距原理,并应用基于此原理的PMD Camcube3.0摄像机进行了亮度图像的标定,矫正了存在的像素畸变.针对摄像机存在的影响距离精度的温度、噪声、系统误差和混合像素误差原因进行了分析,对系统误差中主要的摆动误差进行了补偿,并根据某像素对应三维点与相邻三维点的距离消除了混合像素误差.

英文摘要：

This paper describes the principle of the time of flight, calibrates the intensity image of the PMD Camcube3.0 based on this principle and rectifies the existing pixel distortions, The factors of temperature, noise, system error, mixed pixel er- ror are analyzed for affecting the accuracy of dis- tance. Wiggling error dominating in the system er- ror is compensated in this paper. Eliminate the mixed pixel error according to the distances be- tween the 3d point and its adjacent 3d points.
