Abstract

The invention relates to an automatic measuring device for volume of a grain pile and a measuring method thereof. The measuring device consists of a line laser, a camera, a stepping motor, a motor driver, a control and data processing module, a power adapter, a case and a connector. The line laser is used as a light source to project line laser, and when the line laser is intersected with the surface of the grain pile, a bright bar is generated on the surface of the grain pile. The measuring method comprises the following steps: inputting shot bright bar images to the data processing module by the camera; processing all bright bar images by the data processing module to reconstruct shape of the grain pile; and calculating the volume of the grain pile by combining a known granary structure. According to the invention, the volume of the grain pile can be precisely measured in real time online, and the measurement is simple, low in cost and large in field of view, so that the metering safety of national grain reserves is ensured.

Description

technical field

[0001] The invention relates to a device for automatically measuring the volume and a measuring method thereof, more particularly to a device for automatically measuring the volume of grain piles and a measuring method thereof, which are used in the field of grain quantity inventory supervision. Background technique

[0002] Grain is an important strategic material, and food security is related to the overall situation of China's economic development and social stability. The existing grain quantity inventory monitoring system is still not enough to provide reliable grain reserve information. China still needs to spend a lot of manpower and material resources to control the accurate quantity of grain reserves through the method of annual inventory clearance. In terms of efficiency, accuracy, cost and timeliness There are problems.

[0003] In terms of grain heap volume measurement, traditional methods generally use steel tapes and other length measuring tool...
