Abstract

The invention discloses a pointer type instrument number reading and recognition method and a system. The pointer type instrument number reading and recognition method comprises steps of adjusting relative positions of an image collection recognition device and the instrument to be read, obtaining an accuracy current image of a dial plate area of the instrument to be read, and determining the dial plate area on the collected image without using the complicated image analysis technology like the contour tracing. The invention reduces the calculated amount, and improves the recognition efficiency. Furthermore, the invention performs recognition processing on the collected current image through the recognition module of the image collection recognition device without transmitting the collected image to the computer to process, eliminates the data transmission time and further improves the recognition efficiency.

Description

technical field [0001] The invention relates to the field of reading recognition of meters, in particular to a method and system for reading recognition of pointer meters. Background technique [0002] Pointer instruments are currently the most important measurement tools and are widely used in industrial production and scientific experiments. At present, the readings of pointer instruments still basically adopt the manual reading method. On the one hand, this method wastes manpower and material resources, and is boring; irreparable loss. In recent years, some methods based on computer vision and other artificial intelligence to automatically identify the readings of pointer instruments have been proposed. However, this method generally collects the image of the instrument through an image acquisition device and transmits it to an automatic identification device such as a computer. After contour tracking, image segmentation, etc. and other complex image analysis techniques...
