Problems solved by technology

In fact, since the sensor that collects environmental information is different from a camera or lidar, it does not have a large measurement range, and its measurement range is even limited to points, so it needs to be compensated by a certain method

Embodiment 1

[0036] Embodiment 1: The present invention proposes a method for collecting environmental information based on a SLAM intelligent carrier. Through the collection of various environmental information, the construction of multiple environmental information distribution maps for unknown environments is realized, and by analyzing the surrounding environmental information of the intelligent carrier The distribution realizes the recognition of environmental objects and their characteristics, and assists the intelligent carrier to locate and navigate through the overall distribution and characteristics of objects in three-dimensional space. The multivariate information distribution map includes two or more of the following information: temperature, humidity, atmospheric pressure, light intensity, harmful gas concentration, carbon dioxide concentration, and volatile organic compound concentration.

Embodiment 2

[0037] Embodiment 2: refer to figure 1As shown, the present invention proposes an environmental information collection system based on a SLAM intelligent carrier, including an environmental information collection module, a SLAM intelligent carrier and a remote information processing computer system. The environmental information collection module includes a microcontroller, a temperature and humidity sensor, a barometer, an ambient light sensor, a gas sensor, an infrared sensor, and the like.

Abstract

The invention discloses an environment information acquisition method based on an SLAM intelligent carrier. The environment information acquisition method based on the SLAM intelligent carrier comprises the following steps: acquiring various environment information so as to realize construction of a multi-element environment information distribution diagram for unknown environment, analysing distribution of surrounding environment information of the intelligent carrier so as to realize recognition of environment objects and features thereof, and assisting the intelligent carrier to locate andnavigate through integral distribution condition and features thereof of objects in a three-dimensional space. The invention further discloses a system based on the method, and the system comprises anenvironment information acquisition module, an SLAM intelligent carrier and a remote information processing computer system. According to the invention, the construction of the multi-element environment information distribution diagram for the unknown environment can be realized, and analysis and precision optimization are performed on environment information data through an artificial intelligence algorithm. Different from the space modelling method of a conventional SLAM technology, the method disclosed by the invention can simultaneously perform intelligent carrier positioning assistance,environment feature detection, object recognition, personnel search and rescue and the like, in a specific environment.

Description

technical field [0001] The invention relates to the field of environment detection and the field of electronic information technology, in particular to an application system combining SLAM intelligent carrier and environment information collection. Background technique [0002] Simultaneous Localization and Mapping (SLAM) technology refers to that the robot starts to move from an unknown position in an unknown environment, and locates itself according to position estimation and maps during the movement process, and at the same time builds on the basis of its own positioning. Incremental maps to realize autonomous positioning and navigation of robots. [0003] The maps constructed by the current SLAM technology are mainly location maps, which do not realize the collection and analysis of multivariate environmental data (such as temperature and gas concentration) and the construction of corresponding environmental information maps. In fact, since the sensor that collects envi...
