Camera calibration is a C++/Python library for opencv that facilitates camera calibration. See too CameraCalibrationGUI , a GUI util to generate config files used by this library.
Python:
sudo pip3 install camcalib-jpvolt
C++: See How to build section.
Generate config.json file with the GUI util;
Python:
from camcalib import *
width = 480 # image width
height = 640 # image height
path = "config/config.json" # config file path
cal = Calibrate(path, width, height)
while(True):#main loop
#your code
fixed = cal.fix(original_image)
C++:
#include <camcalib.hpp>
#include <opencv2/opencv.hpp>
#include <opencv2/imgproc/imgproc.hpp>
int main(int argc, char* argv[]){
CamCalib cal("path/to/config.json", img_width, img_height);
for(;;){
//your code
cv::Mat fixed = cal.Fix(original_image);
}
}
