Embodiment Construction

[0017] see figure 1 , figure 1 It is a flow chart of the steps of the method for processing rock core photos in the present invention.

[0018] The method for processing rock core photos comprises the following steps:

[0019] Step S101, setting box markers at the four corners of the box where the core is placed, taking pictures of the core that has been collected in the container, and obtaining a photo of the core;

[0020] In this embodiment, when the rock core photo is taken on site, four orange box markers are placed at the four corners of the rock core box containing the rock core, such as figure 2 shown. The color of the box marker is not limited to orange, because orange is easier to identify. In this embodiment, an orange box marker is used as an example. For the convenience of analysis, box markers of other colors are used.

[0021] Step S102, input the rock core photo into the computer, and read it into the folder named after the corresponding drilling number; ...

Abstract

The invention provides a method and system for processing a core photo by utilizing digital image processing and PDF (Portable Document Format) generation technologies, which can be used for core photo processing and report generation in geotechnical engineering investigation and geological exploration. The method comprises the following steps of: automatically identifying box body markers of four corners of a core box through the digital image processing technology to obtain coordinates of the four corners of the core box in an image; carrying out image transformation by utilizing affine transformation to obtain effects of removing perspective and distortion in the process of collecting the core photo; and finally automatically inserting all photos by utilizing the PDF technology to generate a core photo report. The method and the system for processing the core photo have the advantages of automation, high efficiency and attractive appearance.

Description

technical field [0001] The invention relates to the technical field of geotechnical engineering investigation, in particular to a method and system for processing rock core photos by using digital image processing technology. Background technique [0002] Geotechnical engineering surveys usually carry out drilling operations. According to the existing survey specifications and operating procedures, on-site collection of core photos is required first. Survey units generally use core boxes to place the collected cores in grids, and then use digital cameras to compare them. The core box with the core is photographed, and the drill core report is generated using the photographed pictures. [0003] In large and medium-sized survey projects, due to the large number of cores collected on site, hundreds or even thousands of core photos will be taken. For such a large number of core photos, engineers and technicians need to spend a lot of time to process, and the photo catalog also ...
