摘　　要：为解决双目测量系统传统标定方法过程复杂、应用条件苛刻、很难满足应用过程中准确快速校正的难题,提出了一种简便的校正算法。该算法仅需采集一张平面靶标图像,然后利用多视图几何中的绝对二次曲线特性,即可实现双目测量系统结构参数的校正优化。实验表明,利用该算法可以达到初始标定的精度,满足实际应用的可靠性需求。It is rather difficult to rapidly and conveniently correct owing to the complexity and application condition of the traditional calibration method .In order to solve this issue , this paper proposes a simple and rapid co-rection algorithm , which only needs a single plane target image with the characteristics of absolute conic in the multiple view geometry.The experimental results show that the initial calibration precision can be achieved and the practical application demand can be satisfied by the proposed algorithm in this paper .
