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...
