Visual statistical method for counting underground drill rods

Abstract

The invention discloses a visual statistical method for counting underground drill rods, which specifically comprises the following steps of: firstly, storing a drill rod unloading video, splitting frames, and normalizing the drill rod unloading video; establishing a binary classification data set, and dividing into corresponding categories of a database according to the content of the single-frame image; increasing the number of data sets through a preprocessing method combining rotation, overturning and brightness enhancement; training an improved self-adaptive learning rate ResNet-50 network; detecting the category of each frame of image in the video and outputting a confidence coefficient percentage; and when all the images pass through an adaptive learning rate ResNet-50 model, clearing confidence coefficients of all second-class non-rod-unloading results in the CSV file, filtering video output confidence coefficients by using an integral method, and finally, calculating the number of unloaded rods in the video through a falling edge. The method is high in detection precision, errors caused by model detection can be effectively reduced, the final detection precision is improved, and meanwhile the problem that the detection precision is reduced due to shielding is avoided.

Description

technical field [0001] The invention belongs to the technical field of visual detection, and in particular relates to a visual statistical method for counting downhole drill pipes. Background technique [0002] As a major killer that endangers the safety of underground production in our country, gas always threatens the life safety of underground workers. In actual production, the gas in the coal seam is extracted by drilling pipes, and there is a quantitative requirement for the number of drills, so as to judge the adequacy of the gas extraction capacity. This makes counting the number of drill pipes a problem that needs to be considered when measuring the drilling capacity. How to automatically count the number of drill pipes to avoid potential harm to production safety due to workers' false reports and missed reports is a problem that needs to be solved at present. Thereby reducing the hidden danger of gas safety, ensuring the life safety of underground workers, and redu...
