Abstract

The application discloses a vernier caliper reading recognition method for intelligent supervision and related equipment, and the method comprises the following steps: acquiring the image of the vernier caliper reading by using a camera, the camera is adjusted according to a preset rule in advance, and the vernier scale of the vernier caliper is equally divided according to a preset specification; determining whether the vernier caliper in the image is a digital caliper or a scale caliper by using a trained target detection model; if the vernier caliper is determined as a digital caliper, performing character recognition on the image to obtain the target reading of the vernier caliper; if the vernier caliper is determined as a scale caliper, acquiring the main scale reading and the vernier scale reading of the vernier caliper based on the image, and determining the target reading of the vernier caliper based on the main scale reading and the vernier scale reading. The application can automatically read the reading of the vernier caliper, and the reading can be displayed in smart glasses, thereby improving the electronic degree of the supervision of the power equipment.
