Calibrate frontal camera

[miguelriemoliveira]

@tmralmeida can you do this with @afonsocastro ? Do you have experience with this?

[miguelriemoliveira]

Hi @hellxberg do you have the yaml file for the front camera ? You used the intrinsic value did you not?

@tmralmeida or @bernardomig did you backup the disk on the computer when you installed ubuntu 18.04?

Hi @miguelriemoliveira, I did use intrinsic value of the camera but i didn't use any yaml file. I recorded all the information i have with "rosbag record".

Ok, can you please copy paste here the result of a rostopic echo /.../camera_info
