Embodiment 1

[0075] see figure 1 , figure 1 It is a schematic flowchart of a parking space detection method disclosed in an embodiment of the present invention. Such as figure 1 As shown, the method may include the following steps.

[0076] 101. The parking space detection device captures the environment image on one side of the vehicle through the camera device installed on the rearview mirror of the vehicle.

[0077] In the embodiment of the present invention, the imaging device for capturing the environmental image on one side of the vehicle can be installed at other positions on both sides of the vehicle besides the rearview mirror of the vehicle. As an example to describe. The camera device installed on the rearview mirror of the vehicle can capture the environmental images on both sides of the vehicle, and the embodiment of the present invention will take the environmental image on one side as an example for description. The parking space detection device shoots the environment ...

Embodiment 2

[0094] see figure 2 , figure 2 It is a schematic flowchart of another parking space detection method disclosed in the embodiment of the present invention. Such as figure 2 As shown, the method may include the following steps.

[0095] 201. The parking space detection device detects whether the ambient light intensity around the vehicle is lower than a preset light intensity; if yes, perform step 202; if not, perform step 203.

[0096] In the embodiment of the present invention, when the ambient light intensity is too low, it will affect the shooting of the camera device, so when it is detected that the ambient light intensity around the vehicle is lower than the preset light intensity, the parking space detection device turns on the lights to compensate for the surrounding light intensity of the vehicle. The level of ambient light so that the camera in the vehicle's rearview mirror captures an image of the environment on the side of the vehicle.

[0097] 202. The parkin...

Embodiment 3

[0123] see image 3 , image 3 It is a schematic structural diagram of a parking space detection device disclosed in an embodiment of the present invention. Such as image 3 As shown, the parking space detection device can include:

[0124] The photographing unit 301 is used to photograph the environment image on one side of the vehicle through the photographing device arranged on the rearview mirror of the vehicle;

[0125] An image detection unit 302, configured to detect two adjacent corner points of the first parking space in the environment image on one side of the vehicle;

[0126] The first detection unit 303 is configured to detect whether there is an obstacle in the area between the two first parking corners according to the environment image on one side of the vehicle;

[0127] The ultrasonic detection unit 304 is configured to detect an obstacle between the two first parking corners by using an ultrasonic sensor arranged on one side of the vehicle if the first d...

Abstract

The embodiment of the present invention relates to the technical field of parking space detection, and discloses a method and device for detecting a parking space. In the environment image of the adjacent two corners of the first parking space, according to the environment image on one side of the vehicle, detect whether there is an obstacle in the area between the two corners of the first parking space, and then use the ultrasonic sensor to detect the two parking spaces Whether there is an obstacle in the area between the corner points, if the ultrasonic sensor is used to judge that there is no obstacle in the area between the corner points of the two first parking spaces, take the line connecting the corner points of the two first parking spaces as the benchmark , to determine the position of the first parking space, wherein the central axis of the first parking space passes through the midpoint of the line connecting the corner points of the two first parking spaces. It can reduce the missed detection of parking spaces and improve the success rate of automatic parking.

Description

technical field [0001] The invention relates to the technical field of parking space detection, in particular to a parking space detection method and device. Background technique [0002] In daily driving, the parking scene is a driving scene with a high frequency, because accidents such as collisions and scratches are prone to occur during parking, so parking requires high driving skills. With the rapid development of science and technology, parking assistance technology rises rapidly. At present, the vision-based parking assistance technology generally adopts edge detection technology to detect whether the parking space is free. However, the detection accuracy of the above-mentioned detection method is low. Non-vacant parking spaces, resulting in missed detection of parking spaces, reducing the success rate of parking. Contents of the invention [0003] The embodiment of the invention discloses a parking space detection method and device, which can reduce missed detect...
