The invention provides an impassable area confirmation method, device and equipment and a readable storage medium, and relates to the technical field of Internet of Things businesses, and the method comprises the steps: determining the real-time lane information and road information of a driving vehicle according to map data and the latitude and longitude information of the current driving vehicle; according to the lane information and the road information, determining a plurality of driving vehicles having detour behaviors on the target road; according to the detour time information and the detour longitude and latitude information corresponding to the plurality of driving vehicles, identifying a plurality of target vehicles with effective detour behaviors in the plurality of driving vehicles; and according to the detouring longitude and latitude information corresponding to the effective detouring behavior of each target vehicle, determining an impassable area on the target road. According to the scheme of the invention, the calculation complexity is greatly reduced, and the recognition of the impassable area of the panoramic road can be realized in a refined manner.
Description
technical field [0001] The invention belongs to the technical field of Internet of Things business, and in particular relates to a method, device, equipment and readable storage medium for confirming an impassable area. Background technique [0002] At present, in the technology of confirming the impassable area of the road, computer vision technology is mainly used to collect traffic target information on the road through vehicle-mounted cameras, lidar, millimeter-wave radar or roadside camera perception equipment, and then based on the collected traffic target information Image recognition, including static target recognition and dynamic target recognition, combined with high-precision maps and high-precision positioning capabilities, analyzes whether there is impassable area information on the road. Among them, the adopted lidar, millimeter-wave radar, video acquisition and image processing algorithms all require expensive GPU computing costs and complex digital image p...
