CameraCalibration

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.

How to Install:

Python:

sudo pip3 install camcalib-jpvolt

C++: See How to build section.

Usage:

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);
	}
}
