DRILLING WORK MONITORING USING IMAGE RECOGNITION TOOLS
The paper considers the issue of recording and monitoring the process of determining the well depth. To solve this problem, image recognition methods are used. The purpose of the system to be designed is to improve the quality of drilling operations by solving the task of order handling; reporting on drilling locations; and identifying the well depth using image recognition tools. This paper considers the task of identifying the well depth. The model is built within the interactive Simulink environment using block diagrams in form of oriented graphs. The problem reduces to identifying in the frame a video sequence for the location of a drilling head. The situation is determined by installing a drill-pipe and by the drilling process. To detect the drilling head, the method of finding the angles within a video sequence frame is used. We locate the object boundaries in the input image, using the Canny edge detector method. Then we align the pixel values of the two images by overlapping one of them above the other. After that, a binary image is formed, the contours are defined. Finally, we match the images to obtain the final result for detecting the drilling head and the drill-in pipe. Upon detecting the drilling head, a yellow mark will be placed, while the further movement of the drilling head will result in shifting the yellow mark within the frame. In its initial state, the mark is located in the upper part of the frame. Furthermore, the normal is found. After the normal has been found, we can find the location of the drilling head. If the drilling head is deviated by more than 5°, then a new pipe is being installed. Then we find the pipe. If the drilling head deviation angle is less than 5° and the mark is located in the upper part of the frame, it means that drilling has started, and the pipe must be found. If the drilling head deviation angle is less than 5°, the mark is in the upper part of the frame, and the pipe has not been found, then it means that the pipe has been drilled in. The counter of all pipes increases by 1.
