Abstract：In order to realize the real-time measurement of coal volume on belt conveyor, a method of measuring coal volume on belt based on image processing technology is proposed. The coal image of belt conveyor is collected by online laser instrument and industrial camera. First, the image is preprocessed, including filtering, graying and binarization, and then the bone is reduced by image expansion. According to the baseline of no-load coal-free time and the laser line of real-time acquisition, the coal profile is formed by comparison, and the cross-sectional area of coal quantity on belt is calculated. According to the relationship between cross-sectional area and belt speed of belt conveyor, the volume of coal quantity on belt is measured. The maximum error is 4.2%, the minimum error is 0.9%, and the operation is stable.
