About the 3rd and 4th value of 'marks'.

Hi Teoge, what is the meaning of the 3rd and 4th value of a single vector in 'marks'. The json file describes the 'mark' as {x,y,coordinate,direction,type}, and in the paper {x,y,s,theta}. So the 3rd and 4th value form a vector that describe the direction vector theta?

Sorry for excuse, I make a test and know that it's the x,y of a point to describe the orientation of the corner point. And further, this point is generated by the annotation tool automatically?

The labels are generated by my annotation tool MarkToolForParkingLotPoint.
No, they are not generated automatically, they require manual labelling.
But if you are talking about other things than labelling, like type conversion and file saving, then yes, they are handled automatically by scripts.
