Abstract

The invention discloses a high-speed railway foreign matter invasion detection device and method based on FPGA and deep learning, the device comprises a video acquisition module, an image storage module, two data processing modules and an early warning feedback module, and the video acquisition module is used for acquiring a high-speed railway track monitoring video in real time; the video processing module I is used for training the marked training set by using an improved ICnet neural network to obtain ICnet neural network weights, completing the construction of a track region segmentation model, and dividing a track region of a video into monitoring regions with different security levels; the video processing module II is used for carrying out target detection on the track area by utilizing a target recognition neural network; and the early warning feedback module is used for continuously transmitting each frame of target and image segmentation result to the FPGA for calculation andanalysis, and performing semantic analysis on intrusion behaviors. According to the invention, foreign matter invasion along the railway can be accurately monitored in real time, the actual needs ofthe railway department are met, and the operation safety of the high-speed railway can be effectively ensured.

Description

technical field [0001] The invention relates to the field of detection of foreign matter intrusion on high-speed railways, in particular to a device and method for detecting foreign matter intrusion on high-speed railways based on FPGA and deep learning. Background technique [0002] The rapid increase in the operating mileage and passenger volume of high-speed railways in my country has put forward higher and higher requirements for ensuring the safety of high-speed train operation. Foreign object invasion and illegal intrusion are one of the main sources of emergencies in high-speed railways. Therefore, real-time and effective monitoring and early warning of foreign object intrusion and illegal intrusion is an important basis for ensuring the safety of train operation, improving emergency response capabilities for emergencies, and ensuring efficient operation of high-speed railways. [0003] The existing technology mainly relies on the manual identification of cameras at ...
