Embodiment Construction

[0052] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below in conjunction with the accompanying drawings in this application. Obviously, the described embodiments are part of the embodiments of this application , but not all examples. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0053] High-precision map production is divided into field work and internal work. Field work refers to the process of collecting map data when the collection vehicle goes out, and internal work refers to the process of processing the data collected by the collection vehicle and making it into a high-precision map. Among them, the process of processing the collected data can be divided into: data processing, map d...

Abstract

The present application provides a map data processing method, device and equipment for congested road sections. The method includes: acquiring images of congested road sections collected during the day and point clouds of congested road sections collected at night, and grouping the point clouds to generate multiple candidate Set, select the associated candidate set associated with the image from multiple candidate sets, select the associated point cloud associated with the image from the associated candidate set, fuse the image and the associated point cloud associated with the image to generate a congested road section map data. This application provides a method to reduce the point cloud that can be matched by each image, reduce the influence of the previously collected image on the later collected image, improve the registration rate of the image and point cloud, and obtain the map data of the congested road section.

Description

technical field [0001] The present application relates to the technical field of geographic information surveying and mapping, and in particular to a map data processing method, device and equipment for congested road sections. Background technique [0002] High-precision map production is divided into internal and external operations. The external operation refers to the process of continuously collecting data while the collection vehicle is moving, and the internal operation refers to the process of processing the continuously collected data to produce high-precision map products. [0003] During the field work of the collection vehicle, road congestion is often encountered. Because the vehicles on the road block the signal from the acquisition vehicle, point cloud acquisition cannot be achieved. Urban roads are characterized by congestion during the day and smooth traffic at night. For road congestion, images are collected during the day and point clouds are collected a...
