Power transformer liquid level detection method, device and equipment and storage medium

The invention relates to the technical field of image processing, and discloses a power transformer liquid level detection method, device and equipment and a storage medium, which are used for improving the accuracy of liquid level detection. The power transformer liquid level detection method comprises the steps that a to-be-detected liquid level meter image is obtained, and the liquid level meter image comprises a power transformer liquid level meter; performing scale detection on the liquid level meter image through a preset liquid level detection model to obtain a scale detection result; if the scale detection result shows that no scale value exists in the liquid level meter image, feature recognition is conducted on the liquid level meter image, a liquid level meter feature image is obtained, and the liquid level meter feature image comprises an air window and/or a liquid window of the power transformer liquid level meter; and generating a liquid level value corresponding to the power transformer liquid
