摘要: 利用近景摄影测量原理,开发了一套用于拖曳水池拖曳试验的水下摄影测量系统. 通过在拖车上安装2 个水下摄像头,以一定的频率同步地对被拖物进行连续拍摄,然后对这些像片进行识别和坐标解析处理,从而获得被拖物的运动轨迹和姿态. 该方法是一种非接触性测量手段,不伤及测量目标,不干扰被测物体的自然状态,简单易行. 对该系统进行试验验证和误差分析,结果表明,该系统具有较高的测量精度,是一种可靠、方便的测量方法.

Abstract:

Proposed in this paper is an underwater photogrammetry system for towing test,which is based on the principle of close-range photogrammetry.In this system,two underwater cameras are installed on the towing carriage to take photo synchronously in a certain frequency,and the obtained photos are processed in terms of image recognition and coordinate calculation.Thus,the movement trajectory and the attitude of the towed object is obtained.The system is a non-contact measuring method with simplicity and feasibility,which does not damage the measurement target and destroy the natural state of measured objects.Test and error analysis results show that the developed system is of high measurement accuracy,and that it is a reliable and convenient measuring method.

Key words: close-range photogrammetry, underwater photography, motion measurement, error analysis
