＂bear face recognition＂ wild giant panda： a new trick in the pilot of giant panda national park

　　Xinhua News Agency, Lanzhou, December 21st (Reporter Huang Zemin, David Do) A wild giant panda poked its head out of the bushes, waddled in and paced away. The trees continue to shake, and another wild giant panda "appears"! This is a scene monitored by the dynamic monitoring system of giant panda habitat spatial data through "bear face recognition". The reporter recently saw these precious pictures in Baishuijiang National Nature Reserve in Gansu.

　　In the pilot construction of the Giant Panda National Park, the Baishuijiang National Nature Reserve in Gansu Province built a dynamic monitoring system for the spatial data of giant panda habitat in October this year. The system initially set up 6 field video monitoring points. Through these monitoring points, the staff can see the real situation in the forest area without leaving home.

　　According to the fourth national panda survey, there are 110 wild pandas in Baishuijiang Nature Reserve, Gansu Province. It is very difficult to "meet" wild pandas in the vast forest. A few years ago, with the use of monitoring equipment such as infrared cameras, short videos and pictures about wild giant pandas came into public view in large numbers. However, rangers need to replace dry batteries and memory cards for infrared cameras on a quarterly basis, so they often go over mountains and mountains and have a picnic.

　　Now, the monitoring and protection of wildlife has reached a new level. The reporter saw in the Giant Panda Domestication and Breeding Center in Baishuijiang Nature Reserve, Gansu Province that the monitoring screen occupied the whole wall, and the pictures of six field video monitoring points were clearly visible. He Liwen, director of the Giant Panda Management Office of Gansu Baishuijiang National Nature Reserve Administration, said that after wild animals enter the monitoring area, the system can automatically identify and shoot, and generate folders to store and manage video clips. At present, the panda has the highest system recognition rate.

　　According to the data, the first time the system captured the wild giant panda was at 17 o’clock on November 21.

　　“‘ Bear face recognition ’ It is very similar to the face recognition system, but the former is more difficult. " He Liwen said, "Face recognition only captures facial features. It is impossible for animals to be all positive after they appear, and all kinds of postures will be there." To this end, as early as 2017, the administration began to cooperate with the outside world to train machine recognition accuracy with the help of massive archived photos.

　　The reporter followed the forest patrolman of the reserve to hike up the mountain. On the mountainside at an altitude of about 2,500 meters, the reporter saw a field video monitoring point. As soon as people get close, the camera is aimed at them immediately.

　　"In recent years, monitoring equipment has captured more pictures of pandas and their mothers. This shows that the population is relatively stable. " He Liwen said. (End)
