Prefabricated component automatic fast three-dimensional modeling system

Abstract

The invention relates to a prefabricated component automatic fast three-dimensional modeling system, which comprises an article placing platform, a collection device, an image work station and a controller, wherein the article placing platform horizontally penetrates through the collection device; a prefabricated component is put onto the article placing table; the collection device can reach theother end of the prefabricated component along the article placing platform from one end of the prefabricated component through multi-time movement so as to collect the image information of the prefabricated component; the image work station is connected with the collection device through a data wire and performs space three-dimensional operation on the collected image information so as to build amodel; a digital model of the prefabricated component is further obtained and is output; the controller is positioned on the collection device and is used for controlling the operation of the collection device and the pattern work station. The system has the advantages that the operation is simple; the time required by modeling is short; the efficiency is high; the system is particularly applicable to the modeling of large-span concrete prefabricated components in the fields of rail traffic, bridge engineering and the like.

Description

technical field [0001] The invention relates to the field of prefabricated component detection, in particular to an automatic fast three-dimensional modeling system for prefabricated components. Background technique [0002] As my country's modernization process is accelerating, the prefabricated structural system has developed rapidly. As the main component of the prefabricated structural system, the appearance quality of prefabricated components will directly affect the quality of prefabricated components, and then affect the overall prefabricated structure. the quality of. The general method of shape detection of prefabricated components needs to use measuring tools such as total station, level, laser plummet, tape measure or observe with eyes. This kind of detection method is slow and inaccurate, and it is not an ideal and reasonable method of shape detection of prefabricated components. . [0003] At present, image-based 3D modeling is one of the inspection methods for...

Problems solved by technology

[0003] At present, image-based 3D modeling is one of the inspection methods for the shape quality of prefabricated components. This method has high precision, low cost, and realistic surface texture of the model. The object cannot be photographed from multiple angles at the same time, and it takes a long time. At the same time, due to the influence of human factors, the quality of the photographed photos cannot be guaranteed, which is not conducive to the requirements of rapid detection and greatly reduces the work efficiency.
