Method and system for generating traffic accident scene map through handheld video recording

Abstract

The system comprises eight components (P1: a video recorder, P2: a video processing computer, P3: video processing software, P4: a drawing computer, P5: drawing software, P6: a printer, P7: a calibration ruler and P8: a wireless router) and six steps (S1: handheld video recording, S2: data transmission, S3: video processing, S4: image calibration, S5: field map drawing and S6: field map printing). According to the method, an unmanned aerial vehicle driver subjected to professional training authentication does not need to operate the unmanned aerial vehicle and does not need to apply for an airspace from the civil aviation bureau, flight accident risks are avoided, complex three-dimensional operation is not needed, and simplicity, convenience and rapidness are achieved. Therefore, the system has wider applicability, better practicability and lower technical threshold in various road condition environments such as highways, villages and towns and any other environments capable of being held by hands for video recording, is easier to accept and master by the majority of front-line traffic police, and can practically improve the traffic accident handling efficiency and safety.

Description

technical field [0001] The invention relates to the technical fields of traffic accident scene survey and computer stereo vision, in particular to a method and system for generating a traffic accident scene map by hand-held video recording. Background technique [0002] Traffic accident scene maps play an important role in traffic accident recording, analysis, responsibility delineation, and dispute resolution. Therefore, accurate, simple, fast, low technical threshold, and strong scene universality The survey and drawing tools of traffic accident scene maps have always been The urgent needs of the majority of front-line traffic police. Traditional methods, such as digital camera photography and tape measurement, face great challenges in terms of efficiency, accuracy and data comprehensiveness.

[0003] Chinese patent document CN 107194989 A discloses a system and method for three-dimensional reconstruction of a traffic accident scene based on unmanned aircraft aerial photography, and Chinese patent document CN 114004933 A discloses a A method and device for drawing road traffic accident scene maps. Both of the above two methods use multiple UAV aerial images for complete three-dimensional reconstruction to obtain orthophoto images of the traffic accident scene. Long, professional pilots certified by the Civil Aviation Administration of China are required to operate drones, which leads to high technical thresholds, and the need for legal drone flight airspace leads to poor scene universality, so its practicability is greatly restricted
