def calIntrinsicMatrix(self): '''计算相机内参矩阵''' # 这里的其实是考虑的是无畸变且光心就在画面正中间的情况 # 而且像素尺寸为正方向 fx = fy # FOV是视场角,单位° # 注: FOV这里指的是画面对角线对应的视场角。 # FOV视场角的一半: \phi= (FOV/2) * (pi/180°) # 图像对角线的一半 l = \sqrt((h/2)^2 + (w/2)^2) # tan(\phi) = l / f f是等效焦距 # f = l / tan(\phi) # TODO f求错了,不应该/2 # 导致的问题就是FOV跟实际的FOV不匹配,要比预设的FOV大 f = math.sqrt(self.width * self.width / 4.0 + self.height * self.height / 4.0) / 2.0 / math.tan(self.fov / 2.0 / 180.0 * math.pi) # cx = w/2 # cy = h/2 # TODO 写错了, 这里cx, cy不应该有-0.5 return (f, 0.0, self.width / 2.0 - 0.5, 0.0, f, self.height / 2.0 - 0.5, 0.0, 0.0, 1.0)
It is need to be modified as :
