Problems solved by technology

[0004] Among the measuring tools in the prior art, the tape measure needs to touch the measuring target, and the measuring range is limited, and the operation is inconvenient. Generally, two people are required to cooperate to complete the measuring work
The laser range finder has a large range and high precision, but in order to obtain the bridge coordinate information and size information of the disease, it is necessary to take multiple measurements close to the disease, and manual calculation is required
The total station can be used in almost all surveying fields, but it is not suitable for frequent inspection of bridges. It has complicated preparations, cumbersome operations, incapable of shooting and recording diseases, and has problems such as dead angles in use.

Embodiment 1

[0025] figure 1 It is an implementation flowchart of the bridge structure inspection method provided by the first embodiment of the present invention. The method provided in the embodiment of the present invention can be executed by the bridge structure inspection device provided in the embodiment of the present invention, and the device can be implemented by software and / or hardware. Such as figure 1 As shown, the method provided by the embodiment of the present invention includes:

[0026] Step 101, obtain the coordinate value of the inspection target in the bridge coordinate system.

[0027] Among them, the bridge coordinate system is a coordinate system designed by the designer according to the position, orientation and environmental characteristics of the bridge during the construction of the bridge. After a bridge is built, the coordinate origin of the bridge coordinate system of the bridge and the direction of each axis are fixed and known. Generally, the bridge coo...

Embodiment 2

[0048] The second embodiment of the present invention is based on the first embodiment, and a preferred embodiment is proposed on the basis of the first embodiment.

[0049] Preferably, the operating equipment includes: a high-precision digital pan / tilt, a laser rangefinder, an attitude indicator, and an optical zoom high-definition camera core.

[0050] Among them, the high-precision digital platform is used to obtain the horizontal rotation angle and pitch rotation angle of the operating equipment; the laser rangefinder is installed on the high-precision digital platform, and is used to measure the distance between the operating equipment and the inspection target. Distance; the attitude instrument is installed on the high-precision digital platform for obtaining the deflection relationship between the coordinate system of the operating equipment and the bridge coordinate system; the optical zoom HD camera core is installed on the high-precision digital platform for collectio...

Embodiment 3

[0058] figure 2 It is a structural schematic diagram of the bridge structure inspection device provided by the third embodiment of the present invention. Such as figure 2 As shown, the device provided by the embodiment of the present invention includes: a coordinate value obtaining module 201 , a position determining module 202 and an information collecting module 203 .

[0059] Wherein, the obtaining coordinate value module 201 is used to obtain the coordinate value of the inspection target in the bridge coordinate system. The position determination module 202 is configured to determine the position of the inspection target according to the coordinate value. The information collection module 203 is configured to collect information of the inspection object according to the determined location of the inspection object.

[0060] Further, the obtaining coordinate value module 201 also includes: obtaining sub-modules for respectively obtaining the coordinate values ​​of the ...

Abstract

The invention discloses a method and device for inspecting a bridge structure. The method for inspecting the bridge structure comprises the steps that coordinate values of an inspected target in a bridge coordinate system are obtained, the position of the inspected target is determined according to the coordinate values, and information of the inspected target is obtained according to the determined position of the inspected target. By the adoption of the method and device for inspecting the bridge structure, comprehensive inspection of the bridge structure can be achieved, and automatic re-inspection can be achieved.

Description

technical field [0001] The invention relates to the technical field of bridge monitoring and management, in particular to a bridge structure inspection method and device. Background technique [0002] With the rapid development of the national economy, the construction of bridges and roads in our country is also growing rapidly. In recent years, bridge accidents have occurred frequently, and many bridges collapse every year. The reasons are various, including design reasons, construction reasons, and possibly inadequate inspection work. Before the bridge collapse accident, the bridge disease may have been very serious with obvious characteristics. If the regular inspection work is really implemented, it can be detected early and treated early, so as to avoid major accidents. In the process of daily inspection of bridges, due to the limitations of inspection tools and means, it is difficult to obtain the bridge coordinate information of the disease, and it often takes a lot ...
