2.2 target problems of the specified camera When defining the view matrix, You need to specify the target vector as the parameter, which sets the rotation of the camera. Solution When the camera is selected, the camera position remains unchanged. This means that the rotation depends on the change of the target point

2.1 create a camera: Position, target, and view frustum Before drawing the 3D world to the screen, you need the view and projection matrix of the camera. Solution You can save the camera position and direction in a matrix. This matrix is called a view matrix (view matrix, observation matrix ). To create a view matrix, xNa needs to know the position, target, and

The LM algorithm has a total of three applications in camera calibration.(1) Single-target or double-target, in the case of internal-fixation, the best external parameters are calculated. The corresponding function in OpenCV is FINDEXTRINSICCAMERAPARAMS2.(2) The best internal and external parameters are calculated when the internal and external parameters are not fixed in a single target setting. The corresponding function in OpenCV is CALIBRATECAMERA
