中文摘要: 为了实现单摄像头监控下的三维场景中目标的尺寸测量，本文基于树莓派3代B型视频数据采集设备，利用三维距离函数进行测距并修改了三维距离函数中光轴参数OO'的选择过程，减小了测距中距离的数据误差. 针对传统三维距离函数模型的平面局限性即测量目标部分跳出监控区域地面的情况，提出了一种扩大测量范围的方法，将测量延伸至垂直面实现了单目视觉下三维场景的目标尺寸测量，实验结果表明，本文给出的算法扩大了固定单摄像头下测量的范围，提高了测量精度.
Abstract:To measure the size of target in three-dimensional scene under a single camera, this study uses a three-dimensional environment distance function and optimizes the optical axis parameter OO'. A method of enlarging the measurement range is proposed, which is extended to measuring on the vertical surface. The experiment is based on the Raspberry Pi 3B platform with Raspberry Pi Camera. The results of experiment show that the optimization of OO' improves the measurement accuracy and the method proposed extends the measurement range. The algorithm is simple yet effective and can achieve the performance more flexibly and steadily.
