Dust gridding positioning method and dust gridding monitoring method

Abstract

The invention discloses a dust gridding positioning method and a dust gridding monitoring method, and the positioning method comprises the steps: building a space view field through a plurality of cameras, and obtaining a video image sequence photographed by each camera; identifying a spatial stationary object and spatial coordinates thereof; differentiating two adjacent frames of video images toobtain a grey-scale map sequence, and identifying a moving object and space coordinates thereof, a point cloud graph of high-concentration dust and a point cloud graph of low-concentration dust; performing spatial relative position analysis on the high-concentration dust, the low-concentration dust, a static object and a moving object, and determining a dust generation source; obtaining the spacecoordinates of the moving dust according to the space coordinates of the moving object source and the static object source generated by the dust; and performing spatial deduction and visual tracking on the moving dust based on the migration parameters of the dust to complete continuous tracking and positioning of the dust. Characteristic recognition is carried out on dust through a machine visionsystem, and gridding space positioning of dust in a space to be detected is achieved through combined use of the machine vision system and a sensor.

Description

technical field [0001] The invention relates to the technical field, in particular to a dust grid positioning method and a dust grid monitoring method. Background technique [0002] Dust will be generated in the process of raw material transportation, yard construction, material transfer, production operations, etc. The hazards are as follows: 1) endanger human health; 2) cause dust explosion; 3) reduce visibility, an important part of smog is dust; 4) dirty buildings, etc.; 5) corrode metal facilities; wear; 7) reduce product quality; 8) lead to poor plant growth. In 2018, non-point source pollution prevention and control technology was included in the "2018 National Catalog of Advanced Pollution Prevention and Control Technology (Air Pollution Prevention and Control Field)". In 2019, cities in the north began to implement in-depth emission reduction implementation plans for steel, coking and other industries, requiring steel and coking companies to fully complete accurat...

Problems solved by technology

However, it is only suitable for high-precision detection of dust at local points, and cannot detect dust concentration at any position in the area.

If grid-based and accurate monitoring of regional dust is to be realized, a large number of dust concentration monitors must be densely arranged in the entire storage yard, operation and other places, which will result in high investment costs, complicated installation, and high maintenance costs. Activities such as vehicle movement and personnel operations in fields, operations, etc.
