Hello drwnz,
First of all, thanks a lot for your contribution to modify this program to support the KITTI datasets. I have already run this executable program with sequence-00 (image_0) KITTI Odometry datasets. I found the experimental results as follows and can't obtain the correct calibration result as ground truth described.
Initial guess:
X0 = [0.0, 0.0, 0.0, -180, -90, -90];
After many experiments, I still didn't calculate the correct calibration result through Gradient Descent optimizer.
By the way, I unusually get the core-dump issue if the initial guess was selected poorly well because of bad histogram in mi_cost function.
No matter gsl_minimizer (calib.gsl_minimizer in Calibration_deprecated.cpp) or gsl_minimizer_nmsimplex(calib.gsl_minimizer_nmsimplex in Calibration_deprecated.cpp), these optimizes' procedure are ended in failed status and can't also calculate the correct calibration result.
Could you please provide me for your experimental process and results? What's more, would you get the precise (LiDAR to Camera) calibration results? Thanks for your help.
