摘　　要： 为提高水下移动双目视觉的定位精度,首先建立综合考虑径向畸变和切向畸变的水下摄像机非线性数学模型,然后利用焦距归一化成像平面上的成像点坐标和光轴中心点确定空间点所在的空间直线,最后利用两异面直线公垂线中点作为目标点并利用正交投影法求解。该方法不仅很好地化解水下移动双目视觉空间定位时两投影线不相交于一点的矛盾,而且还具有普遍性。 In order to improve the positioning accuracy of underwater moving binocular vision.nonlinear mathematical model for the underwater camera is firstly established considering radial distortion and tangential distortion,then a straight line with the space points is determined by the imaging point coordinates and the central axis points on the focal length normalized imaging plane,finally,solve the problem by using the crossover point of two different surface line as the target point,along with orthogonal projection method..The method not only well resolve the underwater moving binocular visual space positioning two projection of disjoint from the contradiction,but also has universality.
