Abstract: In order to solve the accuracy for measured results,the intuitiveness、intelligence and non-contact for the measured process for melting temperature of continuous casting mold powder.Based on machine vision technology,a system for melting temperature of continuous casting mold powder is designed and realized.The system establishes a reasonable model of the visual system to eliminate the interference of high temperature scene light,selects a high-exposure industrial camera to image the sample clearly,uses image analysis algorithm to extract effective information from the image,and tracks and recognizes the sample in real time through image tracking technology.The field test shows that the system for melting temperature of continuous casting mold powder based on machine vision can complete the measurement for melting temperature accurately,and the repeatability error is within ±20 ℃,which meets the requirements of YB/T 186 for melting temperature of continuous casting mold powder.
