A double-camera and millimeter wave fusion automobile perception system

Abstract

The invention provides a double-camera and millimeter wave fusion automobile perception system, wherein the hardware part comprises an upper shell, a camera module, an adjusting knob, a lower shell, amain board, an inertial measurement unit chip, two lens brackets, a millimeter wave radar module, a warning lamp and a loudspeaker; the system is characterized in that the camera module is hinged andmounted in a cavity of the lower shell through the two lens brackets; the adjusting knob is further mounted at one end of the camera module, penetrates through an arc-shaped hole and is mounted on the outer side of the lower shell; the main board is further fixedly installed in the lower shell. The warning lamp and the loudspeaker are further mounted at the bottom of the lower shell, and the warning lamp and the loudspeaker are connected with the main board respectively; the camera module is formed by fixedly mounting a left camera and a right camera on an image acquisition plate, and two axes of the left camera and the right camera are parallel to each other; the millimeter wave radar is installed on the central axis of a vehicle. A set of collision early warning system can be provided for new and old motor vehicles, and installation is easy and convenient.

Description

technical field [0001] The invention relates to the technical field of automobile auxiliary driving, in particular: a dual camera and millimeter wave fusion automobile perception system. Background technique [0002] In recent years, the number of civilian car ownership and the number of drivers in our country has increased rapidly, and traffic accidents have occurred frequently. According to the data from the National Bureau of Statistics, in 2015, the number of civil vehicles in my country was 162.845 million, an increase of about 11.5% compared with 145.981 million in 2014. An increase of about 12.9%. In 2015, a total of 187,781 traffic accidents occurred, and a total of 58,022 people died in traffic accidents. [0003] Thanks to the rapid development of sensor technology, electronics and control technology, various active safety technologies aimed at preventing accidents have made rapid progress in recent years, such as lane departure warning system (LDW8), brake assist...

Problems solved by technology

However, since the imaging quality of the dual camera is easily affected by negative factors such as light and occlusion, the measurement distance is short, and any independent device needs to be accurately calibrated, and the calculation cost is high. The requirements for cost, real-time calculation, calculation accuracy and mass production High automotive industry has not yet reached the ideal level of technology
