One of the crowd saw your face recognition drone coming out [Full text]

Science and technology dynamics In the past, in some spy warfare or science fiction movies, there was often a plot to search for locked targets from the crowd through drones. Originally thought that this is a plot in the movie, black technology has become a reality in the movie. According to reports, Taiwan’s drone manufacturer, Jingwei Aerospace, displayed a face recognition UAV system jointly developed with NEC at this year’s Secutech 2017 exhibition. .

According to reports, NEC's face recognition technology in the United States NIST standard testing, the recognition rate of up to 99.2%, the world's best four times in a row, but face recognition to be applied to the drone but face many technical challenges. The prerequisite for face recognition is to capture enough resolution images. However, the drone's shooting height is much higher than that of the general surveillance camera. It is not easy to take a clear face image.

In response to the above problems, NEC uses a multiple comparison face detection method to perform high-speed and accurate detection of angles other than the frontal face; using the perturbation space method, in order to cope with environmental changes, the system records various forecasting angles in advance to avoid Face recognition is affected by changes in ambient light and shade. When the face recognition drone is working, the recognition system will compare the face taken by the air-taking machine with the database, and identify the person who matches the database.
