Description
Technical Field
[0001] The invention belongs to the technical field of geological exploration and relates to an automatic collection device. Background Art
[0002] In the fields of water conservancy and hydropower engineering, geology and mining, cores are cylindrical rock samples taken out of holes using annular drill bits and other coring tools according to the needs of geological surveys and projects. After the cores are collected, they need to be transported to the core warehouse for storage. A large number of physical cores have been accumulated in engineering geophysical prospecting, hydrogeology, mineral exploration and other engineering surveys. The cores are stored in physical form, and the storage and transportation of physical cores are very inconvenient. Not only do they take up a lot of space, but they also have the risk of being gradually damaged over time and after multiple moves.
[0003] In recent years, with the rise and development of digital technologies such as 3D laser scanning, BIM modeling, and real-scene modeling, the 3D real-scene modeling method of digital cores based on close-range photogrammetry technology has provided a new method for core storage and management. However, due to the small diameter of the physical core, the core is difficult to fix, and the blocked part of the core after fixation cannot be involved in shooting and modeling, which makes it difficult to collect core cross-sectional data. According to the survey, the current 3D real-scene acquisition equipment for cores based on 3D real-scene modeling technology can collect core columnar data, but it has not realized the collection of core cross-sectional data. In addition, real-scene modeling has high requirements for photo collection. Usually, real-scene modeling requires an overlap rate of more than 65%, and the interval angle between different shooting points at the same position of the core is <20°. The overlap and angle of core shooting are difficult to control. It is difficult for traditional shooting methods to take photos that meet the modeling conditions, resulting in slow speed and low success rate of 3D real-scene modeling of cores. Summary of the invention

The computer control software workflow is as follows: send instructions to the motor 14.2, rotate the core Y to a certain angle, the camera 4 automatically shoots, and the background performs image preprocessing and modeling processes after the photos are transferred to the specified folder of the computer. The shooting and data transmission are carried out continuously without affecting the next core Y shooting operation.
[0034] The camera 5 on the camera stand can cover the cylinder and cross section of the core Y. The core Y is placed on the rotatable drum 14. The drum 14 automatically rotates the core at a certain angle to perform 360-degree all-round shooting without blind spots. The rotation angle is preferably 15°, so that the interval between adjacent angles of different shooting points at the same position of the core Y is <20°. The real-scene modeling requires an overlap rate of more than 65% to ensure the overlap and angle of the core photos required for modeling, and then the photos are imported into the computer's three-dimensional real-scene modeling software to perform three-dimensional real-scene modeling of the core.
[0035] The device of the present invention is used to automatically collect the three-dimensional real scene of a certain core Y, and finally the three-dimensional real scene model of the core is modeled as follows: Figure 8 As shown, the cylinder and cross section of core Y are clear, which can reflect the real texture and geometric shape of core Y.
