Abstract: Visual SLAM(simultaneous localization and mapping) technology is one of the core technologies of modern intelligent equipment environment perception. It is an important factor driving the development of modern surveying and mapping production mode to intelligent surveying and mapping. Focusing on the visual SLAM environment perception technology, this paper combs the brief technical framework, important algorithms and mapping application mode of typical visual SLAM environment perception in the past 30 years according to the five aspects of feature method, direct method, visual fingerprint database, semantic SLAM and brain-like SLAM; summarizes and analyzes the development trend of visual SLAM environment perception technology in intelligent environment interaction perception, crowdsourcing instant information processing, and diversified perception data service; discusses the application mode of visual SLAM environment perception technology in interactive navigation and positioning, digital twin city construction, real-time surface monitoring and interpretation, crowdsourcing map POI production, unattended geological disaster monitoring and deep space exploration supported by independent interactive ability. At present, the surveying and mapping industry is in a period of major development and transformation. With the rapid combination of visual SLAM environment perception technology and artificial intelligence technology, it will further enable the transformation of surveying and mapping production mode and improve the level of intelligent production and service.

Key words: visual SLAM, SLAM technical framework, environment perception, intelligent surveying and mapping
