Embodiment Construction

[0095] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0096] Such as figure 1 As shown, a smart car collision safety prediction method includes the following steps:

[0097] 1) Use an obstacle detection algorithm based on a single image to determine whether there are obstacles or vehicles in front of the miniature car;

[0098] 2) The processor calibrates the two cameras, uses stereo vision to determine the height and distance of obstacles and transmits the information to the controller;

[0099] 3) The distance measuring device detects the condition of vehicles in two adjacent lanes, provides a drivable area for overtaking and changing lanes, and transmits the information of the drivable area to the controller;

[0100] 4) According to the obtained information, the controller exchanges information with adjacent vehicles, obtains the relevant information of the other vehicle, adopts an adaptive lane-changing s...

Abstract

The invention discloses an intelligent vehicle collision safety prediction method, comprising the following steps: 1) adopting an obstacle detection algorithm based on a single image to determine whether there is an obstacle or a vehicle in front of a microminiature vehicle; 2) a processor calibrates the two cameras, determines the height and the distance of the obstacle by adopting the stereo vision method and transmits the information to the controller; 3) a distance measurement device detects the vehicle condition of the adjacent two lanes, provides a traveling area for overtaking and lane-changing, and transmits the information of the traveling area to the controller. The invention provides an intelligent vehicle collision safety prediction method. The collision safety model is established in the approaching stage, the overtaking lane and the overtaking lane changing stage, the safety monitoring is carried out in the whole stage in the overtaking process, and the safe operation isensured. At the same time, the prediction method of each stage provided by the invention can more sensitively realize the collision prediction, and the safety in the automobile operation process is improved.

Description

technical field [0001] The invention relates to the field of smart car collision safety prediction, in particular to a smart car collision safety prediction method. Background technique [0002] In the prior art, there is a lack of a smart car collision safety prediction method, which enables the use of modern information technology and sensing technology to expand the driver's perception ability during the running of the car, and the external information (such as vehicle speed, Pedestrian or other obstacle distance, etc.) to the driver, and at the same time identify whether it constitutes a safety hazard in the comprehensive information of road conditions and vehicle conditions, and in an emergency, automatically take measures to control the car, so that the car can actively avoid danger and ensure the safety of the vehicle Drive safely, thereby reducing traffic accidents and improving traffic safety. [0003] Therefore, those skilled in the art are committed to developing...
