Problems solved by technology

[0002] The management of road (highway, railway, etc.) assets includes the detection of road assets and the maintenance of road assets. The traditional method of road asset detection is the method of manual inspection, which is not only time-consuming and laborious, but also prone to omissions. The management unit cannot comprehensively , Accurately grasp the situation of the road assets it owns, and it is also impossible to fully and accurately grasp the damage and loss of assets
With the rapid development of highways and railways, this traditional road asset detection method is increasingly showing limitations

Embodiment Construction

[0030] Such as figure 1 The software flow chart of the embodiment of the present invention shown is an embodiment of the road asset detection method based on photogrammetry in the present invention, and the method steps are:

[0031] (1) Set the starting point and end point of road asset detection in the database, and sequentially read the geodetic coordinates (GPS coordinates) of the assets to be detected.

[0032] (2) A step of searching for images that may contain the above-mentioned assets in the stored data images of photogrammetry.

[0033] The stored data of the photogrammetry includes at least an image (jpg file) and the image directory, and the image directory includes the geodetic coordinates (idx file, GPS coordinates) of the image exposure point, and the photographic equipment parameters (inn file) of the image exposure point.

[0034] The geodetic coordinate idx point of the image exposure point is related to the image exposed at this point, which is called image...

Abstract

A method for detecting road property based on photographic measurement includes fetching ground coordinate of property requiring to be detected, seeking image possibly containing said property from storage data image of photographic measurement, seeking image containing said property from obtained image possibly containing said property and detecting said property in image containing said property.

Description

technical field [0001] The invention relates to the field of road asset management, in particular to a detection method of road assets. Background technique [0002] The management of road (highway, railway, etc.) assets includes the detection of road assets and the maintenance of road assets. The traditional method of road asset detection is the method of manual inspection, which is not only time-consuming and laborious, but also prone to omissions. The management unit cannot comprehensively , Accurately grasp the situation of the road assets it owns, and it is also impossible to comprehensively and accurately grasp the damage and loss of assets. With the rapid development of highways and railways, this traditional road asset detection method is showing more and more limitations. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a road asset detection method based on photogrammetry, which has high efficiency and ...
