Yes, but the skateboard is irrelevant is the predicted trajectory. I can see how it's useful to analyse the mode of movement to try to improve predictions but the human moving towards you at X speed should be the principle analysis; it seems, naively, to me; rather than worrying if they're on a skateboard or a snakeboard, etc..
The skateboard is relevant because it could theoretically make a neural network fail to identify a person that needs to be avoided
>human moving towards you at X speed
Lidar systems will work this way. Camera+AI not necessarily, it will still need a way to sense relative speed otherwise you are banking on an AI to identify an obstacle in an image.
