IMAGE PROCESSING METHOD FOR TELEMETRY SYSTEM, IN WHICH GRAYSCALE IMAGE IS CONVERTED TO BINARY IMAGE

摘要

PURPOSE: An image processing method for telemetry system is provided to improve the image processing speed and recognize correctly numbers by processing an image of a number display of a meter. CONSTITUTION: An image capture process is performed to capture a number display part of a meter as a gray scale image. The gray scale image of the number display part of the meter is converted to a binary image. A number part is set up as a search region. Each outline of models is tracked within the search region of the binary image. The tracking data are stored. A desired model is selected by removing the noise from the search region of the binary image. A model recognition process is performed to compare spectrums of the selected model with the practical spectrums of the corresponding model and determining a high correlation number as a model number.
