大场景中物体运动轨迹的测量

Measurement of Object Motion Track in Large Ground Field

提出一种基于旋转摄像机拍摄的物体运动轨迹测量方法。该方法采用旋转摄像机跟踪拍摄运动物体,通过摄像机标定技术建立图像平面与物体运动平面的对应关系,完成对物体运动轨迹的测量。该测量方法解决了单台摄像机拍摄范围和拍摄精度的约束,与多摄像机协同拍摄相比,需要的测量设备少,容易操作,对场地的适应能力强。

A new method is proposed to measure the track of mobile object in large ground field, which uses the rotation camera to extend the range and precision of monocular camera. The method uses the scene compositing technique to align every image to get the homograph matrix between the ground filed and every frame. By recognition and tracking, the object can be located in every frame, and the coordinates are mapped to the real field. Compared with static camera method, the method needs less equipments and is flexible and easy for operation.
