Automotive on-vehicle antitracking device based on computer vision

Abstract

An automotive on-vehicle antitracking device based on computer vision comprises an on-vehicle host unit and a vision sensor used for obtaining and shooting images behind an automobile. A control processing circuit obtains the video stream of the condition behind the automobile through the vision sensor, and identifies and judges the video stream, if a car is in the video stream, identifies the license plate and makes statistic; if the license plate appears frequently in a certain period, a processor prompts through voice, automatically generates tracking car information and stores the license plate and relative image frame in a database; if a person is in the video stream, the control processing circuit identifies the face of the front image, and if the person appears relatively frequently in a certain period, the processor promotes through voice , stores the video frame and automatically generates tracking information. The invention is used for preventing illegal individual track and protecting individual privacy of a citizen from encroachment, in particular preventing the track of paparazzo.

Description

technical field [0001] The invention belongs to the application of computer vision technology, pattern recognition technology and computer communication technology in motor vehicle anti-tracking technology, in particular to a computer vision-based motor vehicle anti-tracking device. Background technique [0002] With the rapid development of my country's national economy, the number of motor vehicles has increased sharply, leading to a small number of criminals using motor vehicles to illegally track personal vehicles, causing the people's personal privacy to be violated, especially the "paparazzi" to film and television singers The illegal stalking of movie stars and movie stars has seriously affected the normal life of these people. Due to the congestion and complicated road conditions of urban roads, it is difficult for motor vehicle drivers to have the energy to find potential stalkers by watching the rearview mirror, so for a long time, people still do not have an effect...
