Asphalt mixture core sample surface image acquirer

Abstract

The invention discloses an asphalt mixture core sample surface image acquirer which comprises a mechanical supporting subsystem, an image acquisition subsystem and an image processing subsystem that are connected as follows: all hardware of the image acquirer are arranged inside a box body of the mechanical supporting subsystem. The image acquirer is characterized in that a mechanical technology,an electric technology and a software technology are comprehensively utilized, a vertical rotating platform and a linear array CCD (Charge Coupled Device) are adopted, a core sample continuously rotates for 360 DEG and a CCD camera continuously acquire images, thus curved surface deformation and splicing difficulty of the traditional core sample surface image acquisition are overcome, and the images are shot by adopting a coder trigger linear array camera, so that integrity of image acquisition is ensured and the core sample is not damaged. According to the analysis result of digital image processing software, the asphalt mixture core sample surface image acquirer is used for guiding asphalt road surface construction, and has remarkable economic benefit and better application prospect.

Description

(1) Technical field [0001] The invention belongs to the technical field of traffic road surface detection, and in particular relates to an asphalt mixture core sample surface image acquisition instrument. (2) Background technology [0002] In the quality management of asphalt pavement, the macroscopic performance of the pavement is closely related to the distribution of the mesoscopic structure. Using digital image technology to quantitatively analyze the mesoscopic structure of the asphalt mixture core sample image to obtain the macroscopic performance of the pavement has become an effective means of pavement quality management. . However, since the core samples will be damaged after being drilled and sampled, and the damage will be more serious after being placed for a long time, it is extremely important to digitally preserve them for later in-depth research. At present, the collection of images of asphalt mixture core samples at home and abroad mainly includes cross-sec...

However, since the core sample will be damaged after drilling and sampling, and the damage will be more serious after being placed for a long time, it is extremely important to digitally preserve it for later in-depth research

At present, the collection of images of asphalt mixture core samples at home and abroad mainly includes cross-sectional images and spliced ​​surface images. Standardized promotion, core sample image acquisition based on CT section, the equipment is extremely expensive, the operation is complicated, and it is difficult to promote; the spliced ​​surface image not only has stitching errors, but also needs to restore the curved surface image for subsequent analysis, which has caused problems for automatic analysis. big obstacle
