Problems solved by technology

[0003] Existing related technology has the wellhead automatic number counting device disclosed in the document "Application of Wellhead Automatic Number Counting Device" in the 02 issue of "Energy Technology and Management" in 2006. This device realizes the research purpose by hardware (revolving door), although it can Preliminary realization of the effect of counting the number of people entering the well, but failed to achieve video surveillance, its intelligence is not high, and it cannot distinguish and identify accidents (false touches or repeated touches) in actual use
In the Chinese utility model patent whose patent number is 98229686.X, a kind of "personnel passing quantity counting device" is disclosed. This device is composed of a counter, a timer, and a counting pedal, and the counting is realized by a trigger signal of the counting pedal. This device also There are the aforementioned disadvantages that video monitoring is not possible, the degree of intelligence is low, and the effect is not ideal

Embodiment

[0066] figure 1 shows the operation process of the present invention, by figure 1 Visible, this miner's access automatic monitoring method comprises the following steps——

[0067] (1) Original video input: a continuous video image sequence is obtained by using a fixed-position camera installed above the mine entrance and exit;

[0068] (2) Moving object detection: When the miner appears within the video boundary, it is detected and processed, the miner is separated from the complex background, the initial position and the direction of movement of the miner are located, and corresponding records are made and sent It is included in the tracking sequence;

[0069] In the described step (2), the main purpose of the detection step is to judge whether there is a human head in a frame image, if it exists, it will be included in the tracking sequence, and participate in the decision-making of entering and exiting after several frames of tracking. Before detection, a series of prepr...

Abstract

This invention provides an automatic monitor method for in and out of miners used in coal mines including: 1, input of original video: utilizing a camera head fixed on the passageway of a mine to get a continuous video image sequence, 2, test of movement objects: testing miners when they appear in the video sphere and recording correspondingly to put it into the being tracked sequence, 3, tracking Stat: tracking miners in the sequence one by one to calculate the sum of the in and out persons to get the sum number of in and out miners.

Description

technical field [0001] The invention belongs to the field of automatic monitoring, in particular to a method for automatic monitoring of miners' entry and exit in coal mines. Background technique [0002] As a pillar industry of my country's national economy, the coal industry has made great contributions to national economic construction and social development. However, due to the wide distribution of coal resources in my country, complex coal mining conditions, serious natural disasters, the overall low productivity level of coal enterprises, relatively weak safety production foundation, and the large number of small coal mines with backward production methods and low quality employees, etc. Constraints make safety the most worrying and most difficult indicator to grasp. At present, major and vicious accidents have not been effectively controlled fundamentally, and small accidents occur from time to time, causing heavy losses to people's lives and property, the country and...
