描述了一种用于记录和重建三维轨迹的方法。一个场景是用2个同步的16毫米摄像机拍摄的。相机相对于外部参考系统的方向可以任意选择，因为它随后由软件从2个胶片上的测试图案的图像坐标确定。然后使用每个摄像机的取向参数从2个胶片上的2维图像坐标重建3维场景。这种方法使各种动物行为可进行定量分析。
A method is described to record and reconstruct 3-dimensional trajectories. A scene is filmed with 2 synchronized 16 mm cameras. The orientation of the cameras, relative to an external reference system, can be chosen arbitrarily because it is subsequently determined by software from the image coordinates of a test pattern on the 2 films. The orientation parameters for each camera are then used to reconstruct a 3-dimensional scene from the 2-dimensional image coordinates on the 2 films. This method makes a variety of animal behaviors accessible to quantitative analysis.
