Drawings

FIG. 1 is a schematic flow chart of a method of the present invention in one embodiment.

Detailed Description

The construction and principles of such a device will be apparent to those skilled in the art from the following further description of the invention taken in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The embodiment provides a traffic infrastructure disease development assessment method based on digital streetscape, which mainly comprises the following steps: collecting a plurality of street view images containing a target object, and sequencing the street view images according to a time sequence; displaying the sorted street view images, measuring and marking target objects in the street view images, and recording measurement data obtained by measurement and marking data obtained by marking as remark information of the street view images; and displaying the street view image and remark information of the street view image for evaluation.

The present embodiment also provides an apparatus for the traffic infrastructure disease development assessment method based on digital street view, which includes: a processor for collecting street view images and ordering the street view images according to a time sequence; the memory is used for storing the street view image and remark information of the street view image; and the display is used for displaying the street view image and the remark information of the street view image.

Example 1

Referring to fig. 1, in the present embodiment, a use example of the method is given, which specifically includes the following steps.

Step 1: first, a target object, which is a traffic infrastructure object to be investigated in the present embodiment, is determined, and the traffic infrastructure object to be investigated, such as a landmark structure or a building, for example, a bridge, a road, a tunnel, a pedestrian path, and the like, may be determined according to a specific event.

Step 2: location information of the object is collected. The method mainly comprises the steps of collecting the name, the road and the nearby landmark building of a target object so as to find the position of the object in a map, and collecting longitude and latitude information of the object. For a landmark building, the position information of the investigation object can be directly determined by a map or a search engine, and for a specific point on a certain tunnel or road, the position information of the object needs to be determined by a nearby road, a landmark building, or the like. The collected location information is typically a name on a map, coordinate information, or latitude and longitude information.

And step 3: the street view images of the position are searched in a plurality of map software respectively, the street view map may contain the street view images of a plurality of time nodes and should be collected as completely as possible, and the collection time of the street view and the street view images should be searched and collected together for subsequent sorting. The map software comprises public digital street view maps such as Baidu maps, Google maps, Tencent maps and the like which can be inquired, and digital street view maps which are provided by government departments, other companies and individuals.

And 4, step 4: and arranging the available street view image list. Street view images gathered from multiple sources are further positioned to a point of view of a location of interest, such as by adjusting the street view images to a position facing the target object under investigation and arranged in chronological order for viewing and subsequent operations.

And 5: showing a list of available street view images. All available street view image lists are arranged in sequence for viewing, so that the available street view image lists can be displayed and arranged in different modes, and the specific arrangement display arrangement mode can be determined according to the requirements and selections of users, such as transverse arrangement, longitudinal arrangement, matrix arrangement, sequential carousel and sequential viewing. Also, for the presentation of the original street view image, the user can rotate, drag, zoom in, and zoom out the street view image to view the object in all directions, and thus know the information in more detail.

Step 6: based on the street view image, the user can mark information in the street view image to generate marked marking data, measure and record size information to generate measurement data, and the marking data and the measurement data can be viewed and exported for analysis. For example, the user may add text label information, simple classification label information, and the like to the street view image, and the user may measure geometric information such as the length, area, and circumference of the object in the street view. The annotation data and measurement data of these users can be stored in a sorted manner in a memory. Preferably, the processor automatically collates the user tagged and recorded information in the plurality of street view images for each object into a report form and automatically arranges in a time series of street view images for viewing, editing and analysis collation by the user.

And 7, obtaining a report of street view images, marking data and measurement data disease information of the traffic infrastructure which are arranged according to the time sequence based on the steps, wherein the street view images, the marking data and the measurement data can be used for evaluating the disease development of the traffic infrastructure.
