【摘要】：舰船的舷角是鱼雷攻击时的重要参数,同时也是海航避碰中避碰线路确定的计算依据。在基于视觉的识别中,获取目标舰船的舷角即可确定其相对拍摄视角,从而大大缩小在全方位视野特征库中的搜索范围,提高识别速度。然而现有的舷角测量方法均是采用连续跟踪解算实现的,无法实时测量。为解决实时测量的问题,首先推导了基于视觉的目标舰船舷角测量原理,然后针对摄像机倾斜的情况提出基于水天线校正的改进方法,最后通过实验验证,结果表明方法简单易操作、实时性好。
[Abstract]:The ship's side angle is an important parameter in torpedo attack, and it is also the basis for determining the collision avoidance line in HNA.In visual recognition, the relative shooting angle can be determined by acquiring the side angle of the target ship, which greatly reduces the search range in the omnidirectional visual field feature database and improves the recognition speed.However, the existing methods of side angle measurement are realized by continuous tracking solution, which can not be measured in real time.In order to solve the problem of real-time measurement, the principle of ship side angle measurement based on vision is first deduced, and then an improved method based on water antenna correction is proposed for the case of camera tilting. Finally, it is verified by experiments.The results show that the method is simple and easy to operate.
