Vision measuring system for large stockyard and stockpile

Abstract

The invention relates to the field of non-contact volume measurement, in particular to a vision measuring system for large stockyards and stockpiles, which comprises a first binocular vision subsystem, a second binocular vision subsystem and a server, wherein the output interfaces of the first binocular vision subsystem and the second binocular vision subsystem are respectively connected with theinput interface of the server; left view analog signals and right view analog signals collected by the first binocular vision subsystem and the second binocular vision subsystem are inputted in parallel to the server; an image information treatment module in the server processes, identifies and understands the digital image signals, and finally outputs the characteristic calculation and the measurement result of the image information. The relative measurement error of the vision measuring system is less than 0.1 percent. The invention saves manual labor to the maximum, and realizes automatic non-contact stockpile measurement. Workload previously needing several days of manual labor can be fully completed in several minutes after the vision measuring system is invented. The invention improves the working efficiency, and at the same time, the intellectualization of raw materials storage and program management can be realized.

Description

technical field [0001] The invention relates to the field of non-contact volume measurement, in particular to a visual measurement system for stockpile volume. Background technique [0002] So far, the stacking and reclaiming operations and planning of incoming and outgoing materials in large-scale raw material yards owned by enterprises such as steel, chemical, and power plants have basically relied on manual operation-based management and construction models, which has greatly affected these enterprises. The improvement of the overall automation and information technology level. [0003] Since the raw materials stacked in this kind of stockyard are all bulk materials, such as iron ore, coke, lime, etc., their volume is always in a state of dynamic change during the production process. Inventory measurement and dynamic management rely on manual measurement, which is inefficient, and it is necessary to shut down for manual measurement at regular intervals, affecting the con...

Problems solved by technology

To be sure, the inventive technology is effective in realizing the computer automatic measurement process of the stockyard, and this technology needs to rely on "the CCD camera set at the corresponding height to the two ends of the stockpile as a high-level visual collection point to collect the panoramic image of the stockpile , set the CCD camera on the walking chassis of the stacker-reclaimer to face the stockpile and walk along the longitudinal track of the stacker-reclaimer, set a mobile vision collection point on the stacker-reclaimer to collect image information of the stockyard, although the image The collection of information is comprehensive. However, due to the fact that the actual site is often limited by objective environmental conditions, it is difficult to "set the CCD camera at a height corresponding to the two ends of the stockpile as a high-level visual collection point", which makes the technology difficult. implementation, which requires a new technology that is more adaptable to the environment
