Embodiment 1

[0044] The method for detecting intersections provided by this embodiment includes:

[0045] Obtaining a road ring view, and extracting ground markers from the road ring view; the ground markers include road indicating straight lines and / or ground arrows;

[0046] When the ground marker only includes a road indicating straight line, detecting an intersection appearing in the road surface ring view according to the road indicating straight line;

[0047] when the ground marker only includes ground arrows, detecting intersections appearing in the road ring view according to the ground arrows; or

[0048] When the ground marker includes a road indicating straight line and a ground arrow, an intersection appearing in the road surface loop view is detected according to the road indicating straight line and the ground arrow. The method for detecting an intersection provided by this embodiment will be described in detail below with reference to the drawings. The method for detectin...

Embodiment 2

[0107] This embodiment provides an intersection detection system, including:

[0108] The acquisition module is used to acquire the road ring view;

[0109] Extraction module, used to extract road indicating straight lines and ground arrows;

[0110]a detection module for detecting the intersections appearing in the road surface loop view; wherein, when the ground markers only include road indicating straight lines, the intersections appearing in the road surface loop view are detected according to the road indicating straight lines; When the ground markers only include ground arrows, the intersections appearing in the road surface loop view are detected according to the ground arrows; or when the ground markers include road indicating straight lines and ground arrows, according to the road indicating straight lines and ground arrows, Intersections appearing in the road loop view are detected. .

[0111] The intersection detection system provided by the embodiment will be d...

Embodiment 3

[0131] This embodiment provides a road intersection detection terminal, including: a processor, a memory, a transceiver, a communication interface or / and a system bus; the memory and the communication interface are connected to the processor and the transceiver through the system bus and complete mutual communication , the memory is used to store the computer program, the communication interface is used to communicate with other devices, the processor and the transceiver are used to run the computer program, so that the road intersection detection terminal executes each step of the above road intersection detection method. In practical applications, the detection terminal includes a vehicle-mounted terminal.

Abstract

The invention provides an intersection detection method and system, a terminal and a computer readable storage medium, and the method comprises the steps: obtaining a road surface surround view, and extracting a ground marker from the road surface surround view, wherein the ground marker comprises a road indication straight line and / or a ground arrow; when the ground marker only comprises a road indication straight line, detecting an intersection appearing in the road surface surround view according to the road indication straight line; when the ground marker only comprises a ground arrow, detecting an intersection appearing in the road surface surround view according to the ground arrow; or when the ground marker comprises a road indication straight line and a ground arrow, detecting an intersection appearing in the road surface surround view according to the road indication straight line and the ground arrow. According to the intersection detection method and system, the terminal and the computer readable storage medium, intersection detection can be simpler, more efficient, quicker and more accurate.

Description

technical field [0001] The invention belongs to the technical field of image processing, and relates to a detection method and system, in particular to a detection method, system, terminal and computer-readable storage medium of an intersection. Background technique [0002] The automatic parking system is an important part of the advanced intelligent driving assistance system. It obtains the parking environment information through the on-board sensors, and helps the driver to control the vehicle to complete the parking after detecting a suitable parking space. In the existing underground parking garage, there is no unified control of the parking space management system, and it is not possible to directly lock the parking space in the underground parking garage, and plan a reasonable path in the background, so the vehicle needs to operate at a low speed autonomously in the complex parking garage Find a suitable parking space. When a vehicle searches for a suitable parking s...
