Overview

SYNOPSIS

$ mrcal-calibrate-cameras --focal 2000
      --outdir /tmp --object-spacing 0.01
      --object-width-n 10 '/tmp/left*.png' '/tmp/right*.png'

... lots of output as the solve runs ...
Wrote /tmp/camera0-0.cameramodel
Wrote /tmp/camera0-1.cameramodel

And now we have a calibration!

SUMMARY

mrcal is a generic toolkit to solve calibration and SFM-like problems originating at NASA/JPL. Functionality related to these problems is exposed as a set of C and Python libraries and some commandline tools. Documentation is available at http://mrcal.secretsauce.net/

Have you tried using the star-shaped feature points detector ?

I really liked your work and your contribution to the calibration of cameras.

I would like to ask about images with incomplete detection, in the documentation you referred to the works of "Thomas Sheps - Why having 10,000 parameters in your camera model is better than twelve", have you tried using their detector to determine corners ?

I have a question about cv.undistPoints and cv.remap.

Hi @dkogan I'm interested in doing an experiment with the camera model: LENSMODEL_SPLINED_STEREOGRAPHIC. I want to see how this model will show itself during the operation of my device.

My application uses the undistPoints function, thanks to which I get the opportunity to create a map of a new undistorted position for each pixel. This allows me to quickly transform at arbitrary points without affecting the entire image.

Using this code, I get an analog of the cv.initUndistortRectifeMap function, and then to get the undistortImage, the cv.remap function is used, which performs the inverse transformation + interpolation. m = mrcal.cameramodel('imgPath') model_pinhole = mrcal.pinhole_model_for_reprojection(m,fit="corners") mapxy = mral.image_transformation_map(m,model_pinhole )

I need to get a transformation map for each pixel so that I can quickly know the new location of the undistorted pixel by index. Blue color - cv.UndistPoint() (opencvModel) Green - mrcal.image_transformation_map() (slined model)

How can i do this ?
