A horizontal line on a distance-time graph close distance-time graphA graph with distance travelled plotted on the vertical axis against time taken on the horizontal axis. shows that the object is ...

Key fact In a distance–time graph, the gradient of the line is equal to the speed of the object. The greater the gradient (and the steeper the line) the faster the object is moving.

Human compares the images acquired from two eyes, to recoginize the distance and the velocity of moving object. In this paper, we measured them using the disparity of two camera images acquired from ...

Lidar measures distance, while radar provides a precise estimate of velocity. This is a bit of an oversimplification, of course.

This paper presents a novel velocity planning method in displacement-time graphs with multiple constraints and optimization goals using deep reinforcement learning. The method formulates the velocity ...
