  • 摘要:

    针对传统单目视觉测量系统测量视场有限的问题,本文提出一种基于双自由度旋转平台的全向空间单目视觉测量方法。首先,对双自由度旋转平台的转轴参数进行标定,用副相机拍摄与双自由度转台固定的棋盘格标定板,对棋盘格角点的位置坐标进行提取并转化到同一相机坐标系下;利用PCA(主成分分析)平面拟合得到初始位置转轴参数中的方向向量,通过使用空间最小二乘圆拟合的方法,得到初始位置时转轴参数中的位置参数;然后,通过转台转动的角度以及罗德里格斯公式将不同位置下相机获取的数据进行坐标系统一,实现水平和竖直方向全向空间下的目标测量;最后,通过高精度激光测距仪验证了本方法的测量精度,并通过与双目视觉测量系统、wMPS测量系统进行比对实验,验证了本方法的全向空间测量能力。实验结果表明,本方法测量精度基本达到双目视觉测量系统水平,但测量范围远大于双目视觉测量,可以满足全向空间测量要求。
