Traffic accident road base map information processing method based on topographic map and image

Abstract

The invention relates to a traffic accident road base map information processing method based on a topographic map and an image. The method comprises a first step of pre-processing topographic map data, a second step of pre-processing image data, a third step of matching the topographic map data processed by the first step and the second step with the image data, a fourth step of selecting various road information on the topographic map data and the image data according to set code requirements and automatically generating a road base map, and a fifth step of revising the road base map through field investigation and plotting. Compared with the prior art, the traffic accident road base map information processing method based on the topographic map and the image has the advantages of being high in mapping precision and full in data covering and the like. The data is easy to transfer and store, and traffic accident management time can be shortened.

Description

technical field [0001] The invention relates to a road base map information processing method, in particular to a traffic accident road base map information processing method based on topographic maps and images. Background technique [0002] The road base map is an important part of the traffic accident scene map. The road base map has many contents and takes a long time to draw. In the process of handling traffic accidents, there are three main ways to draw the road base map: [0003] 1) Directly draw a schematic diagram on site, generally use instruments such as a tape measure or a range finder to measure, and specify the positional relationship between two points by marking dimensions. Such drawings cannot meet the accuracy requirements for accident site responsibility identification; [0004] 2) Draw a scale map on site. This method of operation is too slow, especially at some intersections where accidents occur frequently, where the roads, auxiliary facilities, signs ...

AI Technical Summary

Problems solved by technology

[0003] 1) Directly draw a schematic diagram on site, generally use instruments such as a tape measure or a range finder to measure, and specify the positional relationship between two points by marking dimensions. Such drawings cannot meet the accuracy requirements for accident site responsibility identification;

[0004] 2) Draw a scale map on site. This method of operation is too slow, especially at some intersections where accidents occur frequently, where the roads, auxiliary facilities, signs and markings are relatively complicated. Only used in traffic accidents;

[0007] 1) The relative accuracy is low, and the relative relationship of each object in the road base map is inaccurate;

[0008] 2) On the same road section, the road base maps drawn by different personnel are not uniform, which brings certain difficulties to the judgment of the party responsible for the accident;

[0009] 3) Paper-based road base maps are not easy to save, archive, and transmit and share information;

[0010] 4) Due to the limitation of on-site drawing time, the road base map is relatively random, and the coverage is incomplete

[0012] 1) After the accident, all graphics must be drawn on site, which takes up a lot of time;

[0013] 2) There is a lack of uniform industry standards, and the speed and informationization in the true sense have not been achieved;

[0014] 3) It cannot be promoted and applied on a large scale
