Embodiment 1

[0025] see figure 1 and figure 2 , the parallel measurement device on both sides of the volume of large-scale accumulated materials includes two sets of laser scanning devices arranged in parallel, each of which has a laser scanner (21), a laser ranging sensor (22), and a trolley controller ( 23), a trolley driver (24), a pair of rails (12), a rail frame (11) and a carrying trolley (30), sharing a computer (50), characterized in that the laser scanner (21) is Installed on the carrying trolley (30), through the uniform movement of the trolley (30), the material pile (40) is scanned line by line, and the laser ranging sensor (22) installed at one end of the track (10) synchronously measures the trolley ( 30) and the position of the laser scanner (21), the information of the two sets of sensors is transmitted to the computer (50) and after fitting, the complete outline information of the stockpile (40) can be presented, and then the expected volume of the stockpile can b...

[0028] Implementation example 2: Measurement of the volume of raw material piles in steel mills

[0029] see figure 2 As shown, raw materials in steel mills generally have fixed stacking positions, so the present invention is suitable for stockpile measurement in large raw material stockyards in steel mills. On both sides of the stockpile (40), the transport vehicle roads are reserved, and the two sets of laser scanning measurement equipment are fixed on the ground, while ensuring that the tracks (10) of the two sets of equipment are parallel to each other, and the track (10) is determined according to the actual site requirements. length. Adjust the measurement direction of the laser ranging sensor (22) so that it always faces the laser scanner (21) to measure its offshore distance as the one-dimensional information of the stockpile contour model.

[0030] An operator operates the laser scanning measurement system by using a control interface on a computer (50). After the...

Embodiment 3

[0033] This implementation example is basically the same as the first implementation example, except that the laser scanning measurement system includes a laser scanning measurement device and data acquisition, processing and communication modules. see figure 1 and image 3 , the stockpile profile information collected by the laser scanner (21) and the laser ranging sensor (22) is transmitted to the computer (50) that can process the data through the data transmission cable and interface with a certain communication protocol, and the obtained data is simulated by discrete points. The contour model of the stockpile is reconstructed by combining the scanning curve, and the volume and mass information of the stockpile are calculated by the method of integral reconstruction. This information can be passed to the management through the shared platform, and the management can make timely decisions based on the production plan. The invention is applicable to the volume and quality ...

Abstract

The invention relates to a large-scale piled material volume two-side parallel measuring device and method. In the method, a laser scanner and a laser distance measuring sensor are adopted to cooperate with each other to synchronously collect material pile contour information. The laser scanner is installed on a trolley capable of conducting stable and uniform motion. In the moving process, the laser scanner constantly scans the material pile contour information, the laser distance measuring sensor collects motion displacement of the laser scanner, and two groups of synchronous information forms three-dimensional contour information of a material pile. The trolley moves on a specific track, so that stable motion is achieved. The measuring device is specifically arranged in the mode that two sets of measuring equipment are installed on the two sides of the material pile in parallel respectively so that the material pile contour information can be completely scanned. The collected material pile contour information is transmitted to a PC, the appearance and the volume of the material pile are reconstructed in an integral reconstruction mode, and consequently the volume measurement of large-scale piled materials are achieved. In addition, data obtained through measurement are received by an administrator so that the administrator can make corresponding decisions timely; therefore, the large-scale piled material volume two-side parallel measuring device and method provide a technical support for an enterprise to manage the large-scale piled materials.

Description

technical field [0001] The invention relates to a device and method for parallel measuring both sides of the volume of large-scale piled materials. It specifically relates to an automatic visual measurement method and device that uses laser scanning to collect three-dimensional information on the surface of a large stockpile, reconstructs a stockpile data model through three-dimensional modeling, and then calculates the volume and quality of a stockpile through data processing. Background technique [0002] Some powder or pellets are usually stored in the form of accumulation, such as coal, grain, ore, sand, etc., the volume of these accumulation materials is generally large, and with the implementation of access operations, the inventory is dynamically changing, using conventional The measurement method is difficult to accurately estimate the inventory quantity, and many enterprises still use manual on-site measurement to estimate the volume of accumulated materials. T...
