Embodiment Construction
[0069] Embodiments of the application will be further described below in conjunction with the accompanying drawings:
[0070] In recent years, more and more remote sensing satellites have been launched into space. According to different application purposes, the data obtained by different sensors have different temporal, spatial and spectral resolutions. Due to the limitations of sensor hardware conditions, it is difficult to directly obtain remote sensing images with high temporal resolution and high spatial resolution. Each remote sensing data has a certain scope of application and limitations. However, these data can complement each other to expand its ability to observe the Earth. Therefore, how to integrate images from multiple satellites to generate high-quality dense time series data has become an urgent task for high-frequency and high-spatial-resolution observational research. Space-time fusion technology can perform space-time fusion processing on remote sensing ima...
