根据摄像头成像的几何原理，采用梅涅劳斯定理，建立三维环境距离函数，计算监控区域地面上任意位置到观测点之间的距离，避免了复杂的摄像机标定和图像配准，效果良好。结合跟踪算法，根据运动目标在图像上的像素范围，可以有效确定目标的大小，并可以对运动目标进行初步的形状特征分析。

In this paper,by analysing the geometrical principle of camera imaging ,we generate three-dimensional environment distance function based on Menelaus theorem, which is used to calculate the distance between the actul locations on the ground and the observation point. This method could avoid complicated camera calibration and image matching,and has a good effect on distance measuring. With tracking algorithm and the object pixel area on the image, the height and width of the object would be calculated,then we can further analyse its shape features.
