Portable quick staff-free investigation system of traffic accident scene based on binocular vision

Abstract

The invention relates to a portable quick staff-free investigation system of a traffic accident scene based on binocular vision, comprising portable scene investigation equipment and an information processing system, wherein the portable scene investigation equipment conducts photography investigation and information acquisition by using a synchronous triggering binocular camera; the information processing system comprises an image processing module, a scene draft drawing module and an accident case management module; the image processing module is used for processing the images of investigated pictures to realize coordinate conversion and image mosaicking, which is used for carrying out size marking on the scene draft drawing; the scene draft drawing module is used for drawing, generating and printing traffic accident scene drafts in a mode of combining the invocation of drawing database symbols with the size marking; and the accident case management module is used for carrying out sort management on the investigated pictures, scene drafts and other related information in the form of cases. By using the system, the traffic accident scene is not required to be preprocessed, the equipment is convenient to carry and simple to operate, the measuring accuracy is high, and only one operator can execute the whole operation process.

Description

technical field [0001] The present invention relates to the field of traffic accident scene photogrammetry based on the principle of binocular vision, in particular to a method of using scaleless photogrammetry equipment to photograph the traffic accident scene and using corresponding software tools to perform algorithmic processing on the photos to calculate the traffic accident scene. An investigation and evidence collection system that coordinates the elements of the accident scene and draws a map of the traffic accident scene. Background technique [0002] Traffic accident scene investigation is very important for traffic accident identification and recurrence analysis. At present, most traffic accident site surveys at home and abroad are based on traditional methods such as empirical judgment, tape measurement, and manual drawing, which are prone to information omissions and judgment errors. Once the survey is completed, the site will be removed. If the above problems o...

Problems solved by technology

This survey method also requires preprocessing of the traffic accident scene (placement of calibration objects), and has strong limitations on the traffic accident scene, and is not suitable for large scenes or special scenes (such as narrow lanes, etc.)
