The invention provides an intelligent melting point instrument with machine vision and a melting point measuring method, and a method for measuring an automatic melting point instrument based on machine vision. The intelligent melting point instrument comprises two parts, namely hardware and software, wherein the hardware comprises a light source, an optical microscope, a camera, a heating platform, a temperature sensor, a temperature controller and a computer; and the software comprises an in-out module, an image processing module and a human-computer interface module. The method comprises the following steps of: carrying out gray conversion on the image captured in real time by the camera, and generating a difference matrix; respectively extracting three characteristic values of a contrast, a secondary moment in an angle direction and an average value; carrying out Gaussian normalization on a characteristic vector consisting of the three characteristic values; then calculating the similarity between a polyester chip initial image characteristic vector and a current image characteristic vector; and finally finding temperature values corresponding to an initial melting point and a final melting point according to a similarity curve. Compared with the existing measuring method, the melting point measuring method has the advantages that the measurement repeatability and efficiency are improved, the measurement result is more accurate, and the operation is simpler and more convenient.
Description
technical field [0001] The invention relates to an intelligent microscopic melting point instrument with machine vision and a melting point measurement method, which is an automatic melting point instrument and a melting point measurement method based on the combination of machine vision and pattern recognition technology. Background technique [0002] In the scientific research and production of medicine, chemical reagents, spices, printing and dyeing and other industries, the measurement of the melting point of organic substances is often involved. This is because organic matter plays a vital role in the quality of the product before use or after production. According to the definition of physical chemistry, the melting point of a substance refers to the temperature at which the substance changes from solid to liquid. In the field of organic chemistry, pure organic compounds generally have their specific melting points, but if they are mixed with impurities, their melting ...
