Portable Drilling Coal Sample Imaging Device and Coal Sample 3D Image Acquisition Method

Abstract

A portable drilled well coal sample imaging device comprises a computer, an analysis platform, an imaging instrument and a remote controller. The computer is put on the analysis platform. The imaging instrument comprises an upper cover, a machine body shell and an inner frame; the upper cover is connected with the machine body shell through hinges; the inner frame is arranged in the machine body shell and provided with a side-surface camera; an upper-end camera is installed on the lower surface of the upper cover; a lower-end camera is installed on a lower panel of the inner frame; and all the cameras work together and complete coal sample three-dimensional imaging jointly. The invention further discloses a coal sample three-dimensional image collecting method. The imaging instrument adopts a mature computer image synthesis technology to collect coal sample appearance data, storing of image data of coal samples on a coal exploration site is facilitated, and exploration technology staff are help to collect and process the data in the later period; and moreover, on the premise that the technical requirements are ensured, the imaging instrument is small in overall design size and portable for the exploration technology staff, thus, the working efficiency of coal resource exploration staff can be greatly improved, and data collecting errors are decreased.

Description

Technical field [0001] The invention relates to a portable drilling coal sample imaging device for geological survey and a coal sample three-dimensional image acquisition method. Background technique [0002] Usually, in the process of drilling sampling, it is necessary to describe the sample macroscopically. At present, it is generally manual operation, that is, taking pictures first, and then identifying with the naked eye. This operation method not only requires a lot of work, but also has a high work intensity. Due to the influence of factors, the information obtained is not ideal. For example, the number of photos taken is large, some are blurred and unclear, the position of the scale and the angle of shooting are different during the shooting process, and the recognition of the components in the sample by different observers may be inconsistent, etc., caused by irregularities in the sample. Identifying the influence, the markers of the sample composition are not obvious, e...

Problems solved by technology

[0002] Usually, in the process of drilling and sampling, it is necessary to describe the macroscopic coal and rock of the sample first. At present, it is generally operated manually, that is, to take pictures first, and then to identify with the naked eye. Influenced by factors, the information obtained is not very ideal

For example, the number of photos taken is large, some are blurred and unclear, the position of the scale bar and the angle of shooting are different during the shooting process, and different observers may have inconsistent identification of the components in the sample. The influence of identification, the markers of sample components are not obvious, etc., all of which will lead to the inability of the collected data to be used well in the future
