Speed measuring method and device, and electronic equipment

The invention discloses a speed measuring method, a speed measuring device, and electronic equipment. The speed measuring method comprises the steps of: identifying a moving object from an image frameset, wherein the moving object has an object type and size attribute information; determining a pixel distance occupied by the moving object in the image frame set, and acquiring a mapping relationship between the pixel distance and the size attribute information; tracking the identified moving object, and acquiring a motion trajectory and time information of the moving object in the image frameset; mapping the motion trajectory into a real moving distance of the moving object according to the mapping relationship; and acquiring a speed of the moving object according to the real moving distance and the time information. The speed measuring method and the speed measuring device are adaptive to the actual distance corresponding to the pixels in the image frame set, have the advantages of fast response speed, large detected information volume, easy implementation, reduced cost of setting speed measuring equipment and easy installation, debugging and maintenance.
