Problems solved by technology

However, this kind of equipment cannot accurately determine the movement state of the obstacle itself. Due to the large number of parts inside the car body, it is still difficult to avoid the existence and positional relationship of obstacles that cannot be accurately predicted after the scanning parts are blocked by the car body.

Abstract

The invention discloses a 360-degree dead-angle-free obstacle intelligent detection and early warning method for a vehicle, comprising the following steps that system errors are corrected through the external contour modeling of the vehicle and the correction of a sensor; surrounding areas surrounding the vehicle are classified into an effective scanning area, an ineffective scanning area and a dead angle area; and a trip computer acquires obstacle information through the vehicle-mounted radar sensor, calculates and obtains relative data of obstacles and the vehicle and running data of the vehicle relative to a stationary ground and outputs a two-dimensional top view plane of a vehicle roof from top to bottom. A driver can comprehensively know obstacles, vehicles and other objects surrounding the vehicle at any time through a display. The invention provides accurate environmental information for narrow road driving, lane switching driving and reversing of the vehicle and is a driving safety auxiliary method with extremely high intelligence and applicability.

Description

technical field [0001] The invention relates to a vehicle 360-degree obstacle-free intelligent detection and early warning method, which is suitable for real-time detection of surrounding obstacles and a two-dimensional obstacle environment reconstruction method for various vehicles during driving. Background technique [0002] The rearview mirrors of vehicles in the prior art all have viewing blind spots, and the driver cannot fully understand the obstacles around the vehicle. Even if the reversing radar is used to detect the existence of obstacles and the distance to the vehicle through ultrasonic transmitters and detectors, due to its design of fixed beams for detection, it can only detect the distance of obstacles relative to the sensor, and cannot detect the relative distance of obstacles. Position and scanning characteristics, so the reversing radar can only detect the object information within the fixed azimuth range at the rear of the car body, and cannot provide dri...
