Embodiment Construction

[0024] A kind of active vehicle safety control method based on millimeter-wave radar detection and image recognition of the present invention comprises the following steps:

[0025] Step 1: When the car is driving, the front of the car uses millimeter wave radar to emit millimeter waves to detect whether there are obstacles in the measurement range, and the front image is taken by the camera, and the radar signal and camera signal are transmitted to the central processing unit;

[0026] Step 2: When the radar detects an obstacle, the central processing unit captures the picture of the camera signal and judges whether it is a vehicle through the image recognition module. If it is judged not to be a vehicle, it will not be processed. If it is judged to be a vehicle, it will enter step 3;

[0027] Step 3: If the obstacle is a vehicle, determine the vehicle speed according to the satellite positioning signal, and combine the obstacle signal returned by the radar to determine whethe...

Abstract

The invention provides an active safety control method for an automobile based on millimeter wave radar detection and image recognition and an active safety control device for the automobile based on the millimeter wave radar detection and image recognition. The method comprises the steps of actively probing whether a target (in particular a moving target) exists in front of a single lane and displaying the information of the front side on a vehicle-mounted intelligent information terminal. A system can be used for transmitting a barrier back to the vehicle-mounted intelligent terminal through a camera on the front side; and the terminal can be used for determining whether the barrier is the automobile based on the image recognition. The system can be used for automatically determining a safe distance according to the real-time speed of the vehicle; if the target is in the range less than the safe distance, the vehicle-mounted information intelligent terminal can horn to remind the user; and if the user fails to implement due response, an alarm can be sent out by the vehicle-mounted information intelligent terminal to a vehicle monitoring center, and a remote braking mode is adopted at the vehicle monitoring center to brake the vehicle, so that the active driving safety index can be improved.

Description

technical field [0001] The invention relates to the field of automobile driving safety, in particular to an active automobile safety control method and device based on millimeter wave radar detection and image recognition. Background technique [0002] Traffic accidents occur frequently in our country, causing great loss of life and property. The recent frequent school bus accidents have also made the issue of school bus driving safety widely valued by the society. [0003] my country is a country with relatively complex natural conditions. When vehicles traveling on expressways encounter foggy or rainy weather that causes poor visibility for drivers, traffic accidents such as rear-end collisions are very likely to occur. [0004] Existing vehicle safety is mainly a passive method, and there are the following methods: [0005] 1. When the car is speeding, the speed measuring device (such as GPS speed measuring device) is used to remind the driver to slow down in time; and ...
