Problems solved by technology

Due to the characteristics of ultrasonic radar, a single ultrasonic radar cannot give the specific position of the obstacle, only the distance information
Therefore, the narrow-angle radar or the wide-angle radar will think that there are obstacles at the location of the radar envelope on the boundary of the parking space, resulting in inaccurate parking space detection.

Embodiment Construction

[0046] see figure 1 , a schematic diagram of a vehicle 100 provided in this application. The vehicle 100 includes a parking space detection device 10 , a vehicle body 20 and a radar 30 . The empty parking space detection device 10 is provided in the vehicle body 20 . In addition, the radar 30 is mounted on the vehicle 100, and the present application uses as follows figure 1The shown radar installation method is described, that is, the vehicle 100 is installed with four radars 30, and the specifications of each radar can be the same, and two radars 30 are installed on each side of the vehicle at the front and rear, which can detect the two radars 30 at the front and rear of the vehicle at the same time. The obstacles in each area ensure that no detection area is missed, and the accuracy of the detection data is guaranteed. The radar may be an ultrasonic radar, that is, the detection signal emitted by the radar may be an ultrasonic signal. Ultrasonic signals are mechanical ...

Abstract

The embodiment of the invention discloses a parking space detection method and device, the method is applied to a vehicle, the vehicle is provided with a radar, and the method comprises the steps of obtaining multi-frame data detected by the radar in the moving process of the vehicle, and generating a cost map in real time according to the multi-frame data, the multi-frame data comprises infinite data and non-infinite data; when the radar detects a first frame of the infinity data and continuously detects that the frame number of the infinity data exceeds a first preset threshold value, the radar enters a working state, an idle probability value is increased in the working state, and the idle probability value is the probability that a grid of an envelope of the radar in the cost map is in an idle state; and determining a first boundary of the parking space according to the increased idle probability value. According to the embodiment of the invention, the accuracy of parking space detection can be improved.

Description

technical field [0001] The present application relates to the technical field of automobiles, and in particular, to a parking space detection method and device. Background technique [0002] In the technical components of intelligent networked vehicles, the environment perception system is a crucial part, and it is the guarantee of the safety and intelligence of intelligent networked vehicles. One of the most important sensors for perception of the external environment in intelligent connected vehicles is radar. Radar can provide information on the location, distance, and speed of obstacles, which are crucial to intelligent connected vehicles. Due to the characteristics of ultrasonic radars, a single ultrasonic radar cannot give the specific location of obstacles, but only distance information. Therefore, the narrow-angle radar or the wide-angle radar will think that there are obstacles in the position of the radar envelope on the boundary of the parking space, resulting in...
