摘要
针对低空运动目标的定位问题,提出一种基于标定的数字图像交汇测量方法。首先利用光轴夹角在一定范围的两台数码相机同时获取目标的立体图像,然后利用软件系统实现目标位置参数的解算。该系统不要求两个CCD像机的光轴互相垂直,因此具有较高的实用价值。重点对该交汇测量系统的精度进行了分析,指出相机和标杆的布阵方式以及镜头畸变是影响系统性能的主要因素,并给出了改善的方法。
A kind of digital imaging intersection measuring system based on camera calibration is proposed to position moving target. Using two cameras which include angle between their optical axis is in a certain range, two stereo images are obtained simultaneously. Then, computer system is used to calculate target＇s position parameters. The system has higher practicality value for its lower request including angle between two camera＇s optical axis. Precision analysis had been made and optimized design had been advised for position of overeastting staff and cameras.
