Abstract
Description
[Technical Field] 5
[001] The present disclosure relates to a hyperspectral scanning system for underground mine galleries and tunnels. In particular, the present disclosure relates to a hyperspectral scanning system enables fast and accurate acquisition of information on rocks and minerals on the surfaces of mine galleries and tunnels. The system is equipped with a light source that illuminates in the same direction as the observation direction of the hyperspectral camera, 10 ensuring high-intensity and uniform illumination regardless of the observation direction or angle. [Background]
[002] When applying conventional ground-based hyperspectral scanning systems in galleries 15 or tunnels, the use of artificial light sources is typical. However, since the light source is fixed in a specific position, the amount of light irradiated onto the target surface varies. This variation is further amplified when the camera rotates while recording data, causing fluctuations in light intensity depending on the distance from the target.
[003] As a result, the quality of the acquired data could not be consistently maintained. 2023344510 05 Jun 2026
[004] It is not feasible to obtain three-dimensional information within a gallery using a conventional hyperspectral scanning system platform that employs a tripod and an automatic rotation device. Instead, an additional LIDAR sensor must be used to acquire geometric information, leading to increased time and cost. 5
[005] Furthermore, when acquiring continuous data along an extended gallery, the conventional hyperspectral scanning system platform using a tripod and an automatic rotation device requires both the platform and the light source to be moved separately. This process significantly increases both time and cost. [005a] Any discussion of documents, acts, materials, devices, articles or the like which has 10 been included in the present specification is not to be taken as an admission that any or all of these matters form part of the prior art base or were common general knowledge in the field relevant to the present disclosure as it existed before the priority date of each of the appended claims.
