摘　　要：设计并实现一种基于计算机视觉的室内空间测量系统,通过3个低成本的USB摄像头对室内目标进行图像拍摄,实时测量出目标的空间精确位置。采用张氏平面标定法标定摄像头的内外参数,并针对室内环境特点设计了简单有效的图像处理方法,利用立体视觉定位原理计算出目标点的空间位置信息。实验结果表明:系统测量误差小于15 mm,数据更新率为15 Hz,均可满足室内机器人的定位需要。An indoor space measurement system based on computer vision is designed and implemented,which uses three low-cost USB cameras for indoor target image capture,real-time accurate measurement of the spatial location of the target.The scheme uses Zhang＇s algorithm to calibrate the camera＇s intrinsic and extrinsic parameters,designs a simple and effective image processing method to sovle the influence of indoor environment,and then uses the binocular vision theory to compute the position of the target.The experiment shows that system measurement error is less than 15 mm,the data update rate of 15 Hz,and it meets needs of the indoor robots positioned.
