摘要
以撞网方式回收无人机是符合现代无人机发展方向的回收方式。以此方式回收无人机对近场无人机测距提出了更高要求。本文研究了双摄像机绑定跟踪测距的方法 ,它结合传统光学测距技术和数字图像分析技术 ,与传统的光学测距相比 ,提高了测距速度和精度。本文介绍了双摄像机测距原理 ,给出了空中飞机图像捕捉和目标匹配算法 ,并介绍了测距误差的校正。
A rapid testing method for aircraft′s distance is presented with two fixed television cameras and an image-procession computer. It combines traditional range measurement by an optical instrument with digital image processing technology. Its theoretical foundation is based on computer vision solution scheme (robot vision). Target-catch from the video image and distance-indicated algorithm used in the system is described. The distance resolution of the system is given by the experimental parameter. The way for rectifying the system is introduced. All equipments of the distance indication system are based on the ship or ground, while no instruments are needed in the aircraft. Experimental result in the aircraft range finder system shows that the system is effective and reliable.
