Abstract

The invention relates to a national economy estimation method and device based on noctilucent remote sensing data. The method comprises the following steps: acquiring NPP-VIIRS type noctilucent remote sensing data and preset national administrative boundary data, with the NPP-VIIRS type noctilucent remote sensing data comprising NPP-VIIRS cloudless noctilucent data and stable light source noctilucent data; performing area extraction on the NPP-VIIRS type noctilucent remote sensing data through the preset national administrative boundary data; generating a mask according to the stable light source noctilucent data, and cleaning the NPP-VIIRS cloudless noctilucent data through the generated mask to obtain a to-be-processed noctilucent image; and performing national economic estimation and model improvement according to the to-be-processed noctilucent image. By adopting the method, the accuracy can be improved.

Description

technical field [0001] This application relates to the technical field of intelligent vehicles, in particular to a national economic estimation method and device based on luminous remote sensing data. Background technique [0002] With the introduction of luminous remote sensing technology, researchers began to apply luminous remote sensing data to the measurement and evaluation of regional economy, because luminous remote sensing data can obtain dynamic information of regional economy in a large range, and the data provided are relatively continuous, uniform and spatially located. Clearly, it has advantages that traditional economic data do not have, and this technology can provide strong support for regional economic research. Earth observation science can provide rich spatial information support. Luminous remote sensing is an emerging branch of earth observation science, and it can deeply understand the laws of human activities on the surface from a unique perspective. ...
