Some confusion about Euclidean distance units #15
Description
Thank you so much for such a great scene graph generation tool.
I noticed that you guys also wrote in the paper and in the yaml of case_1_ that the distances are in feet. But I found in RelationExtractor's Euclidean distance calculation that there is no conversion factor about feet and meters. It is not clear to me if the distances are already output in feet when using bev projection in the form of image.
If a dataset of type carla is used, since the Carla simulator documentation states that its distance unit is meters, PROXIMITY_THRESHOLDS: [['near_coll',4],['super_near',7],['very_near',10],['near',16], [' visible',25]] and other relationships regarding distance may not work as well and the specific values need to be redefined.
I'm trying to determine if there is any consideration in your code for the conversion of distance units when using Carla data? If not, I'll assume that meters are used as units when using Carla data.
