Embodiment Construction

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of this application.

[0021] With the development of robot technology, intelligent robots have been widely used in the market, such as substation inspection robots, survey robots, factory handling robots, and restaurant service robots. Due to the complex working environment and large working area, this type of robot even needs to work alternately at different altitudes, so the demand for navigation is relatively high.

[0022] The navigation system is one of the important components of the mobile robot. It can p...

Abstract

The embodiment of the present application discloses a map construction method, device, system, electronic equipment and storage medium. This method obtains the environmental characteristic data of the object to be constructed; then obtains the three-dimensional point cloud data of the BIM model corresponding to the object to be constructed; then fuses the environmental characteristic data and the three-dimensional point cloud data to obtain the target map corresponding to the object to be constructed . By fusing the environmental feature data including the environmental depth information of the object to be constructed and the environmental visual image information with the three-dimensional point cloud data, the data of the target map is enriched, which in turn makes the robot's navigation data more accurate and improves the accuracy of the robot's navigation data. accuracy.

Description

technical field [0001] The present application relates to the technical field of map navigation, and more specifically, to a map construction method, device, system, electronic equipment, and storage medium. Background technique [0002] The navigation system is one of the important components of the mobile robot. It can provide the robot with correct position and attitude information, so that the robot can work in a certain environment and complete the specified tasks. It is also the path planning and obstacle avoidance of the mobile robot. Collision avoidance, the basis of intelligent autonomous control. At present, the common navigation system methods are: electromagnetic navigation, light reflection navigation, GPS navigation, etc. However, limited by signal occlusion and positioning accuracy, existing navigation systems still cannot meet the high-precision positioning requirements of indoor scenes. Contents of the invention [0003] In view of the above problems, th...
