Embodiment Construction

[0035] The present invention will be further described below in conjunction with accompanying drawings and examples of implementation.

[0036] like figure 1 , figure 2 Shown: a coding method using the image acquisition in the virtual assembly of the steel box girder above, including: one-dimensional code, two-dimensional code (1, 2, 3, 4), and positioning picture (9). Among them, the one-dimensional codes are distributed in the upper, left, lower, and right directions of the collected steel box girder mating surface, each image contains four one-dimensional codes, and the four one-dimensional codes are used in turn to represent the steel box girder The block number (5), face number (6), sequence number (7), and other part information (8), so that it can quickly classify all images, find a certain image of a certain face that is needed, and extract The image is shown, among which, other part information (8): When two steel box girders that cooperate with each other are matc...

Abstract

The invention relates to an image acquisition encoding system and method for virtual assembly of a steel box girder. The encoding system comprises one-dimensional codes, two-dimensional codes, a positioning image, a high-definition camera and a computer, wherein the four one-dimensional codes are sequentially used for representing the block number, the surface number, the serial number and other information of the steel box girder; each image comprises four two-dimensional codes; the two-dimensional codes are used for comparison of relations among a plurality of images, rotation angle, image scale and image positioning, so as to complete mutual image stitching; each one-dimensional code is positioned between every two two-dimensional codes to form a rectangle; and the positioning image is used for performing position determination on two mutually matched images. The system and the method have the beneficial effects that through virtual assembly of the large-scale steel box girder, the operating personnel safety is ensured, the labor intensity and resource waste are reduced, and the assembly precision is improved; and through image calibration by use of a coding method, images of the steel box girder can be acquired anywhere in real time, the possibility of confusion is low, less staff is required in the acquisition process, and the recognition accuracy meets the engineering requirement.

Description

(1) Technical field [0001] The invention relates to the technical field of detection and identification, in particular to an encoding system and method for image acquisition in virtual assembly of steel box girders. (2) Background technology [0002] With the increase of economic strength, in order to speed up the construction of bridges, steel box girders are widely used in the field of road bridges, and the weight of a single piece is getting larger and larger. The production is all segmented in a professional box girder processing factory, and transported to the bridge site for assembly and connection. Before the steel box girder leaves the factory, it is necessary to build an assembly base on the ground and pre-assemble it to ensure successful installation and control accuracy and quality. After the assembly is qualified, it will be disassembled and shipped. After disintegration, it needs to be hoisted and loaded, transported to the bridge position, unloaded and stacked...
