Problems solved by technology

[0004] However, due to the limitations of hardware and external conditions, in the process of collecting spatial geographic information data by the vehicle-mounted mobile measurement system, it is easy to be blocked by trees, vehicles, pedestrians and other ground objects on the street, so that the blocked space cannot be collected. Geographical information data, resulting in the lack of data information on the building facades on both sides, making the collected spatial data limited

Abstract

The invention discloses a spatial data acquisition method and a spatial data acquisition system, and relates to the technical field of data acquisition. Sheltered spatio-temporal data of a missing part of a vehicle-mounted moving system can be acquired. The method comprises the following steps: acquiring first spatial data acquired through ground acquisition equipment; acquiring second spatial data acquired through air acquisition equipment; splicing the first spatial data and the second spatial data to obtain spliced spatial data. The spatial data acquisition method and the spatial data acquisition system are mainly used for acquisition of the spatial data.

Description

technical field [0001] The invention relates to the technical field of data collection, in particular to a spatial data collection method and system. Background technique [0002] In recent years, with the rapid development of the geographic information industry, roads and other infrastructures are changing with each passing day, and people's demand for spatial data is also increasing. In order to ensure that traffic management measures on the road are legal and effective, it is necessary to collect spatio-temporal data on both sides of the road or street , to grasp the urban traffic status by analyzing spatio-temporal data. [0003] The vehicle-mounted mobile measurement system is a multiple fusion system that integrates global satellite positioning module, inertial navigation module, 3D laser scanning module, panoramic image acquisition module and distance measurement module. The system can realize rapid and comprehensive spatial geographic information data acquisition. T...
