Problems solved by technology

[0006] However, RGB-D sensors also have the problem that the effective range of available depth values ​​is small. For some open and large scenes, there will be problems with missing depth values ​​or missing feature points, which will affect the accuracy of motion estimation and even cause positioning problems. There is a serious deviation from the construction map

Abstract

The invention relates to the technical field of simultaneous localization and mapping methods of three-wheel omnidirectional mobile robots integrating multiple vehicle-mounted sensors, and particularly relates to an SLAM device integrating the multiple vehicle-mounted sensors and a control method of the device.The SLAM device integrating the multiple vehicle-mounted sensors comprises the vehicle-mounted sensors, a vehicle-mounted encoder, a vehicle-mounted inertia measurement unit, a vehicle-mounted controller and an upper computer; the vehicle-mounted encoder and the vehicle-mounted inertia measurement unit are connected with the vehicle-mounted controller, and the vehicle-mounted controller is connected with the upper computer.The localization and mapping effects of the robots can be improved, the problem of localization and mapping errors brought by depth value deletion or characteristic point scarcity which are generated when SLAM is conducted only by relying on an RGB-D sensor is solved, and therefore the robustness and accuracy of SLAM are improved.

Description

technical field [0001] The invention relates to the technical field of synchronous positioning and mapping method of a three-wheeled omnidirectional mobile robot fused with on-board multi-sensors, and more particularly, to a SLAM device fused with on-board multi-sensors and a control method thereof. Background technique [0002] The omnidirectional mobile robot can realize movement in any direction, and can be widely used in military, industrial, household services and other fields. Simultaneous localization and map creation (SLAM, Simultaneous Localization And Mapping) of mobile robots is a hot research problem in the field of robotics. It is the premise and foundation of self-service task planning and path planning for mobile robots. The SLAM problem of robots, simply put, is that in an unknown environment, a mobile robot needs to build an environment map and locate itself on the map at the same time. This process is similar to a person walking into a completely unfamilia...
