Program code implementation for modified two-step camera calibration, estimating both internal and external camera parameters through algorithmic optimization
Detailed Documentation
In the camera calibration process, two critical steps require program code modifications. The first step involves calibrating the camera's internal parameters, which includes focal length, principal point coordinates, and lens distortion coefficients. This typically requires implementing algorithms that analyze checkerboard pattern images to compute intrinsic camera matrix values. The second step focuses on calibrating external parameters, determining the camera's position and orientation in 3D space relative to world coordinates. This involves solving perspective-n-point problems and implementing coordinate transformation matrices. By optimizing the program code through these modifications, more precise camera calibration can be achieved, significantly improving the accuracy of calibration results through enhanced numerical methods and robust error minimization techniques.
