为解决基于单目视觉的像机空间定位问题,基于射影几何原理,提出了一种利用特殊标志点的空间几何信息和光学像机实现像机与标志点的相对位姿测量,进而推算像机的空间坐标位置的方法。该方法避免了计算过程中对每帧图像都进行复杂的非线性解算,而利用像机与标志物间一种特殊姿态即正视投影作为连续位姿计算的起点和初始值,利用帧间约束来进行后续帧的位姿跟踪计算,达到既保证计算精度,又减少计算量的目的。在试验和实际应用中均取得良好效果。
To solve the problem of camera spatial positioning based on mono-vision,we propose what we believe to be a new algorithm,which is essentially based on the following idea: we find the relative attitude parameters between the camera and the special marked point with the spatial geometrical information of the marked point;then we infer the camera s spatial positioning coordinates with such geometrical information.Instead of complicated nonlinear calculations for each frame,the new algorithm obtains the initial...
