Problems solved by technology

After succeeding, the suspect fled overnight to Hebei Province, covering his face when passing through intersections where there were cameras, and sometimes even selling the stolen cars overnight, which made it difficult to crack the case and recover the stolen cars

Embodiment Construction

[0016] The present invention will be further explained below.

[0017] A vehicle anti-theft system includes a dot matrix projector, an infrared camera, a distance sensor and a microprocessor arranged in the vehicle. Dot-matrix projectors, infrared cameras and floodlights are set on top of the cab glass.

[0018] The distance sensor is used to detect that the driver sits on the driver's seat, and then sends a control signal to control the various devices in the system to start working.

[0019] The dot matrix projector includes a laser emitter and a diffractive light component. The laser emitter is used to emit continuous collimated laser light to the diffractive light component. The positions form coded speckle. The laser is a vertical cavity surface emitting laser with a laser wavelength of 830-950 nanometers. The diffractive light component consists of diffusers and gratings arranged in parallel.

[0020] After the coded speckle is projected onto the driver's face, the i...

Abstract

The invention discloses an anti-theft system for a vehicle. A dot matrix projector, an infrared camera, a distance sensor and a microprocessor are arranged in a cab, and the whole system is started and stopped through the distance sensor. The spot matrix projector is used for emitting structured light to the driver's face and includes a laser emitter and a diffraction light module. The diffraction light module changes the collimated laser emitted by the laser emitter into scattered spots with coding information. The scattered spots with coding information act on the driver's face and the position of a light spot matrix changes and distorts, the image is captured by an external camera, and the microprocessor can reconstruct and obtain the 3D model of the driver's face. The obtained 3D model of the driver's face is compared with the 3D model of the vehicle owner's face to judge whether the driver is the owner by the coincidence degree, and the anti-theft function of the vehicle is achieved.

Description

technical field [0001] The invention relates to an automobile anti-theft system. Background technique [0002] Before major holidays, there is a large flow of vehicles and people, and people tend to take it lightly, providing criminals with opportunities to "get rich". Many vehicles are easy to be stolen, which is basically caused by the owner himself, such as parking at will, placing valuables in the car, and vehicles without anti-theft equipment. [0003] Guangdong: During the "Blade" campaign against vehicle-related crimes in 2014, a total of 280 stolen vehicles were recovered, including 21 vehicles including Porsche, Toyota Highlander, Camry, Reiz, Dongfeng Honda CRV, Civic, Wuling, and Changan Waiting for 27 micro-faced cars. The police pointed out that the number of thefts of mid-to-high-end cars dropped by 49%. In 2013, the number of car thefts fell below 10,000 for the first time in many years. The police also pointed out that most of the mid-to-high-end vehicles ...
