Viewed 20 times 0 I'm encountering an issue with radial distortion in image processing. I'm trying to apply radial distortion to an image using distortion coefficients k_1 = 1 , k_2 = 0.4 and k_3 = 0.2 . According to the ... Web1 and 2 represent radial distortion parameters in the two images respectively (note that 1 may differ from 2). Eq. 1 represents all the information available for estimating the radial distortion and the scene structure. However, the correct radial distortion and point depth cannot be determined from the above equation. We can replace the ground ...
WebThe beams were allowed to propagate to the far field for the phase distortion to manifest as both amplitude and phase distortion. The four copies were then imaged onto the sensor of a CCD camera—initially, a low-cost FLIR Chameleon was used and later replaced by a higher quality FLIR Grasshopper to highlight the role of detector sensitivity. WebFeb 25, 2024 · Therefore, in this paper, an efficient and robust method for a single solution is proposed to estimate the absolute pose for a camera with unknown focal length and radial distortion, using three 2D-3D point correspondences and known camera position.
