Embodiment

[0031] refer to figure 1 , a large-scale scene three-dimensional reconstruction system based on BDS location service, the system includes a sequentially connected BDS location service module, a data processing module, a three-dimensional reconstruction module and a texture mapping module.

[0032] The BDS location service module is provided with a receiving antenna unit supporting active antennas and passive antennas, a radio frequency front-end integration unit for LNA antenna detection, and a communication unit for sending detected location signals and collected image data to the service background Unit, this example uses the ATGM336H-5N-2X module in the BDS / GNSS full constellation positioning navigation module ATGM336H-5N series.

[0033] The data processing module includes preprocessing and feature extraction of the data acquired by the server background, and finally writes the data into the database. The preprocessing of the image includes image enhancement and image deno...

Abstract

The invention discloses a reconstruction method of a large-scale scene three-dimensional reconstruction system based on a BDS location service, which is characterized in that the method comprises thefollowing steps: S1, obtaining scene images by positioning a scene image through a BDS location service module and establishing a panoramic image acquisition system; S2, carrying out data processing and storing the data into a database; S3. modeling in Grassmann space; S4. performing texture and color mapping. This method can obtain real-time scene image, match accurately, and quickly build 3D model. It can overcome the problem of large accumulated error and huge data overhead space in traditional 3D reconstruction of large-scale scene.

Description

technical field [0001] The invention relates to the technical field of scene three-dimensional reconstruction, in particular to a large-scale scene three-dimensional reconstruction system and reconstruction method based on BDS location service. Background technique [0002] The 3D reconstruction of large-scale scenes has become one of the development trends of computer vision in the future, and the 3D model has become the fourth multimedia data type after images, sounds and videos. It also has important and extensive application prospects. Currently, the existing 3D reconstruction methods for large-scale scenes are usually image reconstruction methods based on ordinary camera models. Due to the limitation of the perspective of ordinary computers and image reconstruction are not suitable for 3D reconstruction of large and complex scenes, it is urgent to propose an efficient and practical method. Method for 3D reconstruction of large scenes. [0003] At present, there are ro...
