Method for collecting information of night traffic accident scene

Abstract

The present invention discloses a method for collecting information of a night traffic accident scene. The method comprises the steps of preparing a collection device, wherein the collection device is a remote control drone with a high-speed infrared camera, a light emitting diode (LED) surface light source and a high sensitivity camera; after people arrives at the night traffic accident scene, firstly, marking traffic elements by using a light stick; controlling the high-speed infrared camera to shoot each marked traffic element closely and takes a plurality of close-up photos by surrounding each element; controlling the drone with the LED surface light source and the high sensitivity camera to fly around the ground accident scene and take photos; splicing a series of aerial images so as to acquire a panoramic image of the accident scene, establishing a close-up index of all traffic elements according to colors, and linking to the close-up photos taken by the high-speed infrared camera and the high sensitivity camera, so as to prepare for detail analysis. The method is simple and convenient to carry out; various conditions are provided when the information of the traffic accident scene is collected; and a condition of the accident scene can be recorded clearly, thereby facilitating post-processing.

Description

technical field [0001] The invention relates to the technical field of traffic accident investigation, in particular to a method for collecting site information of traffic accidents at night. Background technique [0002] With the rapid development of the economy, there are more and more vehicles, and traffic accidents are inevitably accompanied by convenience. The rapid development of science and technology makes the era of manual measurement and survey of traffic accident sites gone forever. It is replaced by digital, high-speed and accurate traffic accident measuring instruments. At present, there are reports on methods of collecting traffic accident scene information based on close-range photogrammetry and aerial images. However, the existing methods have great deficiencies in the fixation and collection of accident scene information at night. The main problem is that ordinary cameras cannot clearly record many elements of the accident scene under low-light conditions. ...
