Based on the UAV tilt photogrammetry, multi-sensor data fusion and AI-assisted mapping technology, the fast acquisition and mapping system obtains the real three-dimensional model of the target scene in a fast and intelligent fusion way through functional modules such as real-time data transmission and fast fusion mapping. It can meet the requirements of different industry scenarios such as geographic mapping, urban management, public security, natural resources protection, forest and grass protection, emergency communication, and power inspection.
