Thermometer automatic reading system based on image processing

The invention discloses an automatic thermometer reading system based on image processing, and belongs to the technical field of pressure thermometers. The system is composed of a computer, an intelligent thermostatic bath, a standard device, a measuring instrument, an image acquisition device and a detected thermometer. The intelligent thermostatic bath is used for providing a standard temperature environment; wherein the communication module is in communication connection with a computer through an RS232 bus. The measuring instrument and the etalon are used for reading a standard indicatingvalue. The measuring instrument is in communication connection with the computer through the RS232 bus. The image acquisition device is used for acquiring an indicating value image of the detected thermometer. An image is uploaded to a computer through a USB data line. The computer identifies the representation value image of the image acquisition device. System software controls the intelligent thermostatic bath to autom
