Abstract

A method and device for measuring the speed of an object, the method comprising: for each frame of images in at least two frames of images in an image sequence, acquiring image information of the frame of images, the image information including depth information; Detecting objects in the frame of images based on the depth information to obtain object detection results; performing object tracking based on the respective object detection results of the at least two frames of images to obtain object tracking results; and based on the object tracking results, and The time difference between the at least two frames of images is used to calculate the detected speed of the at least one object.

Description

technical field [0001] The present invention relates to the field of image processing, and more particularly, the present invention relates to a method and apparatus for measuring the velocity of an object. Background technique [0002] How to efficiently and accurately measure the speed of an object has always been one of the hot spots in the field of monitoring. Taking the case where the object is a vehicle as an example, monitoring the driving speed of a vehicle is of great significance for avoiding urban road congestion and rationally planning travel routes. [0003] Currently, in one method, the driving speed of the vehicle is monitored through a vehicle-mounted GPS (Global Positioning System, Global Positioning System). However, in this method, an additional GPS device needs to be installed on the monitored vehicle. The accuracy of this method can be severely compromised when the GPS unit fails or cannot communicate with the satellites due to reasons such as tunnels....
