Embodiment 1

[0043] This embodiment is basically as attached figure 1 Shown: A method for high-precision acquisition of coal and rock geological images in a low-illumination environment, including the following steps:

[0044] Step S1, select the acquisition object under the coal mine in the low-light environment; figure 2 As shown, the collection objects include roadway 1, roadway single side 2, excavation face 3 and coal mining face 4;

[0045] Step S2, according to the different collection objects, use the warm and cold light source adjuster to supplement light according to the pre-stored light supplement strategy; fill light strategy;

[0046] The roadway supplementary light strategy is, when the acquisition object is a roadway, use cold light with a color temperature in the range of 7000-9000K for supplementary light; use the structural settings of the roadway itself and the dark environment caused by no lighting equipment, use this range of cold light for supplementary light It can...

Embodiment 2

[0067] This embodiment is basically the same as Embodiment 1, except that: when collecting the images of the roadway 1 and the single side of the roadway 2, the images are collected at intervals of 0.6 meters.

[0068] Set the separation distance according to the normal pace of adults, and collect images at a distance of 0.6 meters, so that the staff can move more smoothly and improve the efficiency of image collection. At the same time, reducing the separation distance will also increase the number of image collection, ensuring The final accuracy of the collected images meets the requirements.

[0069] The specific implementation process of this embodiment is the same as that of Embodiment 1, the difference is that:

[0070] The fourth step is to collect the image of roadway 1. The collector holds a digital camera, so that the center of the captured image of the digital camera coincides with the center of the plane of roadway 1. From one end of roadway 1 along the central axi...

Embodiment 3

[0074] This embodiment is basically the same as Embodiment 1, the difference is that when collecting the image of roadway 1, cold light with a color temperature of 9000K is used for supplementary light, while ensuring uniform illumination and an illumination angle greater than or equal to the viewing angle of the camera.

[0075] Because the laneway 1 is relatively long and completely dark, the color temperature of the cold light is set to the highest level for supplementary light, which can maximize the brightness and ensure the high precision of the collected images.

[0076] The specific implementation process of this embodiment is the same as that of Embodiment 1, the difference is that:

[0077] The second step is to collect the image of roadway 1, and use the warm and cold light source adjuster to fill in light according to the pre-stored roadway light supplement strategy, that is, use cold light with a color temperature of 9000K to fill in light, while ensuring uniform i...

Abstract

The invention relates to the field of mineral exploration, and discloses a coal rock geological image high-precision acquisition method applied to a low-illumination environment. A cold and warm light imaging mechanism is adopted to carry out targeted light supplement on each acquisition object in a coal mine, and acquisition equipment is utilized to carry out image acquisition on each acquisition object according to a preset acquisition strategy. The method can acquire a high-precision coal rock geological image and ensure the safe operation of mineral work.

Description

technical field [0001] The invention relates to the field of mineral exploration, in particular to a high-precision acquisition method of coal-rock geological images in a low-illuminance environment. Background technique [0002] Geological cataloging is an important basic technical work to support the safe and efficient production of coal mines. Timely, accurate and objective records of geological phenomena constantly revealed in excavation engineering, screening and processing of useful geological information, research on geological conditions and their changing rules, and providing scientific and reliable geological information for safe production in mines are the key to geological work in modern mines. fundamental requirement. The methods of traditional geological cataloging in the field are backward, and the internal work is cumbersome. Due to the great influence of the geological staff's professional quality and personal habits, the geological cataloging results lag b...
