WebJan 8, 2013 · While the distortion coefficients are the same regardless of the camera resolutions used, these should be scaled along with the current resolution from the calibrated resolution. The process of determining these two matrices is the calibration. Calculation of these parameters is done through basic geometrical equations. WebApr 5, 2012 · The only problem I have now is why is the dist_coefs vector is 5 elements long when returned from the calibration function. the documentation says " if the vector contains four elements, it means that K3=0".

"WebOct 5, 2024 · By using a lens we get better quality images but the lens introduces some distortion effects. There are two major types of distortion effects : Radial distortion: This type of distortion usually occur due unequal bending of light. The rays bend more near the edges of the lens than the rays near the centre of the lens. " - Distcoeffs matlab
