A novel system, based on two video cameras, is developed to quantify the position of a moving subject. Human operators will track the subject with cameras that rotate. The innovative feature of the system is its ability to record the pan and tilt directions of each camera as the cameras are moved. The direction angles are measured by optical shaft encoders and stored on the image at video frame rates in bar code format. These angles and the pixel coordinates of the subject in the video images will be used to calculate the position of the subject in three-dimensional space. The data gathered will establish the feasibility of building a portable video camera system to study animal locomotion out of doors.

一种新的系统，基于两个视频摄像机，被开发来量化的位置的移动对象。人类操作员将用旋转的摄像机跟踪目标。 该系统的创新功能是能够记录每个摄像机移动时的平移和倾斜方向。方向角由光轴编码器测量，并以视频帧速率以条形码形式存储在图像上 格式.这些角度和视频图像中对象的像素坐标将用于计算对象在三维空间中的位置。所收集的数据将建立一个便携式摄像机系统的可行性，研究动物运动的门。
