Detects "people" in the news railroad crossing by AI and 3D image analysis ... Seibu Railway has started the introduction test

Seibu Ikebukuro Line / Ikebukuro No. 9 railroad crossing

Seibu Railway has introduced a system that indicates a stop signal on a train approaching the railroad crossing when detecting abnormalities in the railroad crossing (mainly stagnation of people) by AI or 3D image analysis.Started.See related images. Seibu Railway has developed a joint crossing system in a railroad crossing by analyzing a camera image mainly for "people" in the railroad crossing with multiple manufacturers for the purpose of improving the safety of the railroad crossing.rice field.As a result of the precision verification on the field for about three years, a stable detection ability has been confirmed, so the introduction exam will begin at a relatively high -ranged crossing of people and bicycles.In this exam, we will examine the "link between the abnormal detection system and the special signal emissioner" and "Remote crossing status status of railroad crossings".Special signal emissions (a stopped signal on the train and inform you of the abnormality of the railroad crossing, mainly when the train is approached in a railroad crossing, mainly in the railroad crossing.Works) and informs the driver the danger.In parallel, the test of two types of devices, "Railroad crossing AI monitoring system" and "3D image analysis monitor surveillance system" will be conducted in parallel so that the detection system can be introduced according to the status of each railroad crossing.Furthermore, by grasping the status of the railroad crossing in real time by the camera, the function to support smooth safety confirmation is also verified.The monitoring system and the situation are grasped independently, and the special signal light emitting machine operates even if the communication of the situation is interrupted.Until now, if "people" were left behind in the medical crossing, the holding of the emergency button by the person was sure to notify the train of abnormalities.This time, the railroad crossing AI monitoring system to be introduced and the 3D image analytical railroad crossing monitoring system has excellent detection performance of "people", and can be installed easier and cheaply compared to conventional disorder detection devices.The Seibu Railway aims to introduce full -scale after 2022 based on the results of the introduction exam.◆ Railroad crossing AI monitoring system Resident crossing AI monitoring system uses AI in the railroad crossing from the railroad crossing camera image to recognize the shape of the object.With multiple AI algorithms: "object detection" that detects stays of objects such as cars and "skeletal detection" to detect people's movements and stays, the cars and people in the railroad crossing are quickly detected with high accuracy.In the skeletal detection, the skeleton of the person in the image is detected by the joint point extraction of the image by deep learning and the connection status of each joint point.By learning the strength of the connection between joint points, it is possible to detect people with high accuracy.In addition, a low -light camera is used for the AI camera, and image analysis can be performed at night.Cooperative manufacturer: Oki Electric Industries, Marubeni Network Solutions Ikebukuro Line, Ikebukuro No. 9 railroad crossing (Toshima -ku, Tokyo) December 14, 2021 -March 31, 2022 Ikebukuro Line / Tokorozawa City (Tokorozawa City, Saitama Prefecture)) December 16, 2021 ～ March 31, 2022 ◆ 3D Image Analysis Surveillance System 3D Imager Analytical Railroad Crossing Service, an image analysis by a 3D camera with built -in left and right lenses, the left and right cameras of the left and right cameras.The distance, height, and volume can be recognized as in the eyes, and high -precision detection of those left behind at the railroad crossing is possible.Since there is no detection of light or shadow without volume, performance that is not affected by the natural environment can be expected.Cooperative manufacturer: Computer system research institute Shinjuku line, Iogi No. 2 railroad crossing (Suginami -ku, Tokyo) 2021 -March 31, 2022 ★ If you find a danger within the railroad crossing, as beforePress the emergency button of the impact notification device.
