Abstract

The invention provides a pointer type instrument panel identification method and system and a storage medium, and the method comprises the steps: obtaining a certain number of pointer type instrument images in different scenes, carrying out the marking of instrument type labels, and obtaining a training data set; inputting the training data set into a target detection neural network for training to obtain a trained instrument detection model; inputting the to-be-identified instrument image into the instrument detection model for prediction to obtain an instrument prediction vector, wherein the instrument prediction vector comprises an instrument type, an instrument panel center coordinate and the size of an instrument panel prediction frame; and according to the instrument prediction vector, cutting at least one instrument panel in the to-be-identified instrument image to obtain at least one instrument panel image. According to the method, the target detection neural network is trained by using the large-sample instrument image under the complex condition to obtain the trained instrument detection model, simultaneous detection of a plurality of instruments under various complex scenes is supported, and the identification accuracy and efficiency of the instrument panel are greatly improved.

Description

technical field [0001] The present application belongs to the technical field of instrument identification, and in particular relates to an identification method, system and storage medium of a pointer instrument panel. Background technique [0002] Pointer instruments are widely used in the industrial field and there are many types. Its advantages are: extremely high adaptability to the environment, strong anti-interference ability, especially in harsh environments, such as digging tunnels, mines and other scenarios; sensitive and rapid response to monitoring data, and short delay time. The reading operation of pointer instruments is often performed by a large number of professional staff. With the development of artificial intelligence technology, intelligent inspection robots are gradually replacing manual inspections for monitoring industrial equipment. The intelligent inspection robot uses the camera to collect the instrument image information of the equipment and pip...
