about the code for mapping the boxes about coperception

@RoboticsYimingLi By chance, do you still remember what these lines were doing?
In the meanwhile, @zjr-bit , please try commenting out lines 439 to 442. If the program still works as intended, it most likely means that these lines were only for temporal debugging purposes, and we forgot to remove them.

@dekunma OK，I will check it. I'm more interested in the line436, because I'm doing the same thing on your V2XSim in my repo. I'm confused by the line436.
Thanks for reply!

Hi @dekunma , maybe I get the answer. It seems that the line 436 is used to convert the left-hand coordinate system into right-hand coordinate system. As you wrote in the paper V2X-Sim, I thought your open data have already finished the conversion.
But I get one more question. As the paper says Note that we invert the y-axis in CARLA and use a right-hand coordinate system following nuScenes, why the line 436 seems to invert the x-axis.
Do I misunderstand?
