Abstract

The embodiment of the invention discloses a logging curve automatic tracking method and device based on pixel optimization and electronic equipment. The method comprises the steps that S1, pixel information of each pixel point in a logging image is acquired; s2, giving an initial tracking point on a logging curve in the logging image, and performing transverse tracking according to the initial tracking point, a given color threshold and a given transverse tracking distance; s3, obtaining the current optimal point in the next row of pixels, and carrying out the lateral tracking according to thecurrent optimal point, the color threshold and the lateral tracking distance; and S4, the step S3 is repeated until the distance between the initial tracking point and the current optimal point exceeds the given longitudinal tracking distance, and a final logging curve is obtained. According to the method, the logging curve can be quickly, accurately and automatically extracted from the logging image, and the anti-interference effect is good.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of image processing, and in particular to an automatic logging curve tracking method, device and electronic equipment based on pixel optimization. Background technique [0002] Well logging curve is a common carrier for recording logging information in the process of oilfield exploration and production, and it is of great significance to guide oilfield development. Due to the large number of measured parameters, various instruments of many companies are involved in the logging process, and the logging data is often given in the form of curves in pictures, which requires automatic extraction of picture logging curve data. [0003] Due to the interweaving of a large number of background grids and curves or curves in the image of well logging curve drawings, the curve tracking is interrupted, and manual connection is required, so automatic curve extraction is very difficult.
