Benefits of technology

This invention describes an approach that uses multiple sensor systems (such as cameras) together with vehicles' radars or vision devices to detect road areas during operation without interfering them by other things like cars. It improves security measures while still allowing drivers to see what they are doing well at night time.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving the efficiency and accuracy of autonomous driving systems through detecting road conditions around them without overwhelming their ability to perceive everything they see outside during normal driving operations.

Embodiment Construction

[0038] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0039] see figure 1 As shown, this embodiment discloses a detection method based on multi-sensor fusion drivable area, the steps include:

[0040] Obtain the visual data points collected by the vehicle-mounted vision sensor and the target data points collected by the vehicle-mounted radar in real time; wherein, the visual data points include the type and position coordinates of obstacles, the types of obstacles include vehicles, pedestrians and roadsides, and the target data points Including the type, position and speed of the target, the type of the target includes vehicles and pedestrians;

[0041] Filter out the visual data in each lane and generate the visual data point set of the corresponding lane Camera_lane i _dataset; and filter out the target point data in each lane and generate the target data point set Mmw_lane for the correspondi

Abstract

The invention discloses a detection method and system based on a multi-sensor fusion drivable area, and a vehicle, and the method comprises the steps: carrying out the nearest distance solving and data association calculation of data points of each lane, carrying out the comparative analysis of an association result, taking the data point with the highest existence probability as a cut-off point of each lane, and finally outputting the cut-off point. By means of the method, the drivable area can be detected in real time, the maximum passable range of each lane can be continuously output, the defects caused by missing detection of a single target detection module are effectively overcome, the safety of the whole vehicle is improved, and an effective judgment basis is provided for planning and decision making of an unmanned driving system.
