【摘要】：艦船的舷角是魚(yú)雷攻擊時(shí)的重要參數(shù),同時(shí)也是海航避碰中避碰線路確定的計(jì)算依據(jù)。在基于視覺(jué)的識(shí)別中,獲取目標(biāo)艦船的舷角即可確定其相對(duì)拍攝視角,從而大大縮小在全方位視野特征庫(kù)中的搜索范圍,提高識(shí)別速度。然而現(xiàn)有的舷角測(cè)量方法均是采用連續(xù)跟蹤解算實(shí)現(xiàn)的,無(wú)法實(shí)時(shí)測(cè)量。為解決實(shí)時(shí)測(cè)量的問(wèn)題,首先推導(dǎo)了基于視覺(jué)的目標(biāo)艦船舷角測(cè)量原理,然后針對(duì)攝像機(jī)傾斜的情況提出基于水天線校正的改進(jìn)方法,最后通過(guò)實(shí)驗(yàn)驗(yàn)證,結(jié)果表明方法簡(jiǎn)單易操作、實(shí)時(shí)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.
