Diwei Erxiang CVPR2022 AI satellite helps the space age

On June 20, local time, at the International Computer Vision and Model recognition meeting of the Electrical and Electronic Engineers Association in 2022 (abbreviated with CVPR 2022), China Land Second Space Technology (Hangzhou) Co., Ltd. (hereinafter referred to as "Diwei II" Star.vision) won two runner -up in the Multiearth 2022, which is the only aerospace company on the list.

CVPR is held by the Electrical and Electronic Engineers Association (abbreviated as IEEE), and is the international top international conference in the field of computer vision and mode recognition. The world's major AI giants and unicorn companies, such as Ali, Shang Tang, and Vision, have proved their strength in the CVPR competition. The computer vision event was held in New Orleans, USA.

The CVPR 2022's Earth and Environmental Multi -Mode Challenge revolves around the theme research of biodiversity changes, habitat loss, and climate change caused by the reduction of Amazon Yulin. The two sub -items of the CVPR 2022 Earth and the Environmental Model Challenge -matrix supplement and multi -mode image translation have achieved runner -up. Because it is difficult for researchers to enter the rain forest area, satellite remote sensing technology provides a strong tool for tracking the situation of the situation in the Amazon area. However, the limitations of seasonal weather, clouds, smoke, and optical sensors bring obstacles to obtaining continuous time sequence images. These two task sub -items provide a new perspective for long -term sequence monitoring of rainforest changes, making up for the shortcomings that the optical satellites are severely affected by clouds and mist.

The Agriculture Vision of the CVPR 2022 aims to study and develop innovative and effective algorithms, use remote sensing images for crop classification, and use the global crop type data set provided by the University of Maryland and NASA HARVEST. The time -controlling convolutional neural network algorithm created by the Earthly Second Creation has efficiently and accurately completed the classification task of the ground observation time sequence. The algorithm is temporarily ranked first in the rankings of the three countries of Kenya, Brazil, and Dorge.

Diwei II is a high -tech enterprise dedicated to integrating AI technology with the aerospace industry. The industry evaluated its achievements on CVPR 2022, indicating that aerospace companies have made good breakthroughs in the strong fields of software companies.

Dr. Kang Yashu, the person in charge of the AI ​​R & D of Diwei II, said that Diwei II hopes to use spatial technology to "improve the earth". "For the first time, we participated in the traditional AI company's top AI competition CVPR. Inspiring, it also determines the development direction of our combination of satellites and AI. "

"I haven't seen anything before, just for the perspective. Change often starts from unexpected places." The person in charge of Di Wei said. Diwei II deployed the leading AI platform on the satellite to directly complete the process of data collection, data processing, and data analysis, which changed the current satellite data and information acquisition process.

First of all, let the satellites really "see what you see." Most of the large amounts of data shot by the transmission rate, contact with the ground stations, remote sensing satellites) have not been used. Diwei II innovation uses satellite-data compression technology. Under the premise of inconsistency, 65,000 remote sensing pictures are transmitted in real time throughout the day, totaling more than 190T data, which is equivalent to 6 million square kilometers of original observation data.

Secondly, it is to make satellites "everything you want." Photos of traditional satellites are often not easy to use. Diwei II uses an AI algorithm based on more than tens of millions of square kilometers of images for automatic cloud detection to ensure that the viewing of the photos is high and the amount of cloud is low. This algorithm can also detect different objects such as aircraft, ships, automobiles, buildings, and large -scale populations to achieve active detection and analysis of these key goals.

Again, the satellite "with a golden eye with a fire eye with a golden eye". In the past, subject to physical restrictions, more clear images could only blindly increase lens size, improve precision manufacturing technology, and increase the number of satellite manufacturing costs and launch costs. The real -time satellite image enhancement algorithm of Diwei II breaks through the physical limitations of the physical limit.

Diwei Er allowed satellites to realize multi -functional and multi -scene all -weather use in the fields of space perception, space resource utilization, land observation, communication and computing platforms. At present, the company has opened up the markets of more than 40 countries around the world, and customers spread throughout China, the Middle East, North Africa, Southeast Asia, and South America.
