Problems solved by technology

[0005] Although the presentation of the above-mentioned discrete point data is intuitive, it seems very disorganized, because an object measured by radar is composed of several radar points. Through this display method, it is difficult to present the application purpose of radar data, and it is difficult for users to intuitively understand Its safety level, especially in vehicle applications, cannot achieve the safety reminder purpose of radar

Abstract

The invention discloses a detection presenting method, device and system for objects around a vehicle and the vehicle. The method comprises the following steps: acquiring data information of an object position point closest to the vehicle from a radar database according to a preset detection cycle; judging whether the distance from the closest object position point to the center of the vehicle is smaller than a warning distance threshold; if yes, acquiring a pixel point corresponding to the closest object position point in a presented image and a deviation pixel value of a corresponding radar point, on the outermost layer of warning line in the presented image, deviating towards the center of the vehicle, wherein the presented image includes a vehicle identifying picture and multiple layers of warning lines distributed around the vehicle; redrawing multiple layers of the warning lines according to the deviation pixel value; and displaying an identifier of the closest object position point in the presented image and multiple layers of the redrawn warning lines replacing multiple layers of the warning lines according to corresponding pixel points. According to the method, potential collision dangers around the vehicle can be detected based on radar and can be visually presented.

Description

technical field [0001] The invention relates to vehicle technology, in particular to a method, device and system for detecting and presenting objects around a vehicle, and a vehicle. Background technique [0002] Radar is basically installed on existing vehicles to detect objects around the vehicle. For example, when the user is reversing the vehicle, the reversing radar installed at the rear of the vehicle will detect the obstacle road at the rear of the vehicle and prompt the danger distance. [0003] The data collected by radar is discrete point data. The way to present radar data in the prior art is: the most intuitive way to present two-dimensional radar point data is to display all collected radar points on a base map. [0004] In the process of realizing the present invention, the inventors found that the above-mentioned presentation method of discrete point data has at least the following problems: [0005] Although the presentation of the above-mentioned discrete ...
