This is a package for camera calibration in Julia.
How to install
] add CameraCalibrations
How to use
First we build the calibration object based on the
files: the image files of the checkerboard,
n_corners: the number of corners in each of the sides of the checkerboard, and
checker_size: the physical size of the checker (e.g. in cm).
using CameraCalibrations c = Calibration(files, n_corners, checker_size)
Then we can use that object to calibrate pixel coordinates and/or images, given the extrinsic image we want to refer to:
i1 = RowCol(1.2, 3.4) # a cartesian index in image-pixel coordinates xyz = c(i1, 1) # convert to real-world coordinates of the first image i2 = c(xyz, 1) # convert back to pixel coordinates i2 ≈ i1 # true
- This is currently (1/4/2023) the only package for camera calibration in Julia.
- It allows for calibration using any number of image (even one).
not use this
- Detecting the corners of the checkerboards and calculating the camera-model's parameters is done used OpenCV.
- You can't supply it with in-memory images, just file names.
