A driving recorder and its control method

Abstract

The invention discloses an automobile data recorder and a control method thereof. The automobile data recorder is used for large-scale automobiles. The automobile data recorder comprises a host central processing unit (CPU) embedded with a graph-based zebra crossing recognition module. One output end of the CPU unit is orderly connected to a left lamp switch control module and a left pedestrian crossing signal lamp with a black-and-white zebra crossing lampshade in series, and the other end of the CPU unit is orderly connected to a right lamp switch control module and a right pedestrian crossing signal lamp with a black-and-white zebra crossing lampshade in series. The CPU unit is embedded with a module for graph-based segmented recognition of movement tendency of pedestrian on the zebra crossing. The left and right pedestrian crossing signal lamps are respectively used for showing other automobiles at left and right sides for the current automobile and give a prompt about movement tendency of pedestrian in an automobile body shadow-caused zebra crossing dead zone so that when a large-scale automobile reduces a speed or stops to give way in front of a zebra crossing, traffic accidents of other automobiles going through the zebra crossing at left and right lanes are reduced.

Description

technical field [0001] The present invention relates to the field of traffic safety on road pedestrian crossings (zebra crossings), in particular to a driving recorder for large vehicles and a control method thereof. When it detects pedestrians on the pedestrian crossing (zebra crossing) through the video, it will remind other vehicles in the left and right side lanes in the same direction in the form of external signal lights to pay attention to the driving safety of the pedestrian crossing (zebra crossing). Background technique [0002] At present, in order to ensure the smooth flow of the road, most of the pedestrian crossings set on urban block road sections only have the traffic signals of pedestrian crossing lines (zebra crossings) and pedestrian crossing warning signs. If someone rushes out in the direction where the line of sight is blocked, traffic accidents are likely to occur. When the person in the direction where the line of sight is blocked is riding a bicycle,...

AI Technical Summary

Problems solved by technology

Large vehicles tend to start slowly, so when the green light is on, the driver of a small vehicle in the side lane may think that there is no one on the pedestrian crossing (zebra crossing) and is the first to start first. , traffic accidents may occur, so on a pedestrian crossing line (zebra crossing) with red lights on, traffic accidents may also occur when the vehicle driver has a blind spot for pedestrians on the pedestrian crossing line (zebra crossing)
