product introduction

The bionic binocular vision technology simulates the human visual mechanism, and studies the intelligent vision system including information collection, transmission, processing, understanding and storage. The online self-calibration technology based on motion measurement can perform real-time three-dimensional analysis of the scene in the driving area. Reconstruction, combined with deep learning network framework and multi-task network fusion mechanism, realizes end-to-end real-time pantograph-catenary target detection and tracking and parallax stereo matching to realize pantograph-catenary geometric parameter calculation.

The bionic binocular pantograph-network real-time online monitoring system is an industrialized product developed by the company in conjunction with the bionic vision system laboratory of the Shanghai Institute of Microsystems, Chinese Academy of Sciences. Pantograph-catenary status, integrity of pantograph-catenary structure, catenary geometric parameters, arcing, temperature, bow vibration, contact line wear and other functional detection, the system has vibration compensation, positioning functions and unified timing functions to ensure the accuracy of detection; Highly integrated integrated monitoring equipment has the characteristics of small size, light weight, low power consumption, easy installation, etc., and is also real-time, comprehensive, expandable, and interchangeable; it can meet harsh conditions such as vehicle body vibration, high temperature, and high pressure. The use environment is very suitable for outdoor detection tasks.
