Street view data acquisition and measurement method

Abstract

The invention provides a street view data acquisition and measurement method. The street view data acquisition and measurement method comprises the following steps: providing vehicle-mounted street view data acquisition system, wherein the vehicle-mounted street view data acquisition system comprises a three-dimensional laser scanner, a GNSS / IMU (Global Navigation Satellite System / Inertial Navigation Unit) integrated positioning and attitude determination system and a panoramic camera; acquiring point cloud data by utilizing the three-dimensional laser scanner; acquiring time position and attitude data by the GNSS / IMU integrated positioning and attitude determination system in real time; acquiring panoramic image data carrying positions and attitudes by adopting the panoramic camera; resolving the point cloud data and fusing the point cloud data with the time position and attitude data to obtain WGS84 geodetic coordinate system laser point cloud of a ground object; matching the point cloud data with the panoramic image data; establishing three-dimensional model data according to the WGS84 geodetic coordinate system laser point cloud and the panoramic image data carrying the positions and the attitudes. The system provided by the invention can be widely applied to the fields including three-dimensional digital cities, urban management component surveying, expressway reconstruction and expansion, transportation infrastructure construction measurement, three-dimensional measurement of mines, navigation channel embankment measurement, three-dimensional measurement of island reef shorelines and the like.

Description

technical field [0001] The invention relates to the field of surveying and mapping, in particular to a method for collecting and measuring street view data. Background technique [0002] Street View is a reality map service. Provide users with 360-degree panoramic images of cities, streets or other environments, and users can obtain an immersive map browsing experience through this service. Through Street View, you can truly see high-definition scenes on the street as long as you sit in front of the computer. It is a good tool for traveling and driving, just like the GPS in people's hearts. [0003] But at present, the street view map can only be viewed, and the specification data (length, width and height) of the building cannot be obtained according to the street view map data. Contents of the invention [0004] The invention provides a method for collecting and measuring street view data, comprising the following steps: [0005] A vehicle-mounted street view data ac...
