Script to update Kalibr calibration toolbox to use opencv 4 (allows compiling on ubuntu 18.04).

updatekalibr2opencv4.sh

#!/bin/sh


# update from old OPENCV to the newest OPENCV 3/4
# https://github.com/CMU-Perceptual-Computing-Lab/openpose/issues/912#issue-377202823
# place this file in your /kalibr/ directory and run it

# -> you will still need to comment out cvStartWindowThread(); function calls
# -> aslamcv_helper.hpp needs to be corrected for the pointer logic
# 		-> cv::Ptr<cv::Mat> _pts(new cv::Mat(1, N * N, CV_32FC2));
# 		-> cv::Point2f* pts = (cv::Point2f*) (_pts->data);
