Stone slab surface profile size measurement device and measurement method thereof

Abstract

The invention discloses a stone slab surface profile size measurement device and a measurement method thereof, and relates to a measurement device for building stone and a measurement method thereof. The measurement device comprises hardware parts and software parts in which an image pickup system, a camera control system and a mechanical movement and supporting mechanism are arranged; and the hardware part comprises a stone slab workbench, a camera supporting post, a camera transverse movement and vertical movement guide rail and a camera transverse movement and vertical movement driving servo motor. The method comprises the following steps of: putting the stone slab on the workbench, adjusting the height and the central position of the camera, shooting the stone slab, transmitting the image into a computer and performing image processing on the image through a Visual Studio (VC) ++ software to obtain the appearance and the edge profile of the stone slab so as to compute the size of the slab. The invention realizes the online measurement of the stone slab, can facilitate the scientific management of the slab for a factory, simplify the production step, save the time, improve the utilization rate of raw materials, improve the quality, and reduce the cost.

Description

technical field [0001] The invention relates to a measuring device for building stone and a measuring method thereof, in particular to a measuring device and a measuring method for the surface profile of a large stone slab which is optimally processed in the production process of the stone slab. Background technique [0002] In the existing stone slab processing measurement, manual measurement is generally used to measure the surface shape and profile size of the polished stone slab, and to sample and measure the subsequent cutting of the stone slab. The work is very cumbersome, and the measurement The error is large, and the utilization rate of the stone is reduced. At the same time, this manual measurement method is not convenient for continuous operation and scientific management of stone processing factories. [0003] At present, Italy Brighton Company has developed a special software for stone bridge cutting machine. A camera is installed on the bridge cutting machine,...

Problems solved by technology

[0002] In the existing stone slab processing measurement, manual measurement is generally used to measure the surface shape and profile size of the polished stone slab, and to sample and measure the subsequent cutting of the stone slab. The work is very cumbersome, and the measurement The error is large, and the utilization rate of stone is reduced

At the same time, this manual measurement method is not convenient for continuous operation and scientific management of stone processing plants.

[0003] At present, Italy Brighton Company has developed a special software for stone bridge cutting machine. A camera is installed on the bridge cutting machine, and the camera collects images, and then carries out image acquisition and subsequent processing, and optimizes the arrangement of the plates. An automatic control and intelligent selection system for stone slabs integrating design and processing, but the structure is complex

However, there are few related researches in China. Zhejiang University and Tianjin University have studied the online detection system of ceramic tile geometry, but there is no relevant report on the online surface measurement system and related devices of large stone slabs in China.
