Hello everyone !
Tell me if it is possible to calculate the distortion coefficients (k1, k2, k3,) without calibration, knowing the internal parameters of the camera (matrix resolution 640*480 pixels, pixel size 4 x 4 um, focal length of the lens 6 mm. )
Is it even possible to do this without calibration? Are there any formulas that allow you to calculate the distortion coefficients based on the sensor and lens data described above?
