摘要
通过对排种器性能检测的特点分析 ,提出了由单摄像机和平面镜组成的摄像系统标定方法。建立了该系统的数学模型 ,并给出了一种基于该模型的摄像系统标定方法。该系统的特点是组成简单 ,仅用单摄像机和一个平面镜就能检测多目标的运动规律 ,提高了机器的运算速度。试验表明 :这种方法是快速而有效的 ,与现有的其它方法相比能更好地处理目标的重叠和短暂消失等情况。
By analyzing the detecting features of seed metering device, a calibration method of camera system that is only composed of a single camera and a flat mirror is proposed Based the camera system model, the calibration method of the whole system is precisely deduced Motion law of dynamic targets, such as falling group of seeds, in short distance is detected in the system, increasing calculation speed Experiments show that method can handle the overlapping and timely missing problems efficiently and effectively, comparing with other existing methods
