(Original title: Ali Dharma Academy upgrades remote sensing AI technology to support intelligent flood control)

Netease Science and Technology News, August 5, recently, during the critical period of flood control in the country, Alibaba Dharma Academy urgently upgraded its remote sensing AI technology, developed a water body identification algorithm for flood control, and supported relevant monitoring and monitoring by the Ministry of Water Resources. Analysis work.

It is understood that in key areas with super-alert water levels, the number of processed images has increased by 5 times than usual, and the speed of image analysis has increased by a hundred times, which can improve the level of intelligence in flood control.

Specifically, in this flood season, due to climatic constraints such as clouds, fog, rain, etc., optical remote sensing has greater limitations, and synthetic aperture radar (SAR) remote sensing imaging is required. Using transfer learning technology, the optical remote sensing AI algorithm is transferred to SAR image analysis. Within 1 week, a water body recognition algorithm for the critical period of flood control was developed and trained.

It is reported that since July, Dharma Academy Remote Sensing AI has assisted relevant departments in completing 262 riverside house identification tasks and 149 water body identification tasks.
