About Converter world <--> cam conversion hack
Opened this issue · 1 comments
In the world <--> cam conversions in the Converter module, a self.hack=0.4 parameter is used to modify the z coordinate (camera).

How is this parameter obtained? I suspect it has something to do with the hack to convert gps -> world coords. This hack has changed in subsequent carla versions due to new conventions in the maps, so I suspect I need to update this calcuation as well. I can do that for the new conventions if you can point me to how 0.4 was obtained. Thanks!
Also, here the focal lengths in x and y are set to unequal but from following the sensor declaration in carla, this shouldn't really be the case

Where does the unequal focal length in x and y come from?
