In order to figure waste density and how much waste should be fed into a furnace, it is important to understand any changes in waste volume. In this study, a system was developed for calculating the volume of waste in a hopper using a stereo image processing technique equipped with a digital camera that has three CCDs for obtaining the surface shape of waste in the hopper. First, accuracy of the distance measurement using the digital camera with three CCDs was achieved to establish a method for automatically collecting data and calculating volume by using a computer and a camera. This system was applied to measure the volume of real waste in a municipal solid waste incinerator. The surface shape and the volume of real waste in the hopper were continuously measured and calculated. The results, using the stereo image processing technique, were in almost perfect agreement with those using a laser distance meter. As a result, it was confirmed that the link-up between the system calculating waste volume using the stereo image processing technique and a waste compaction and feeding model can create an advanced waste feeding system that estimates the volume and weight of waste fed into furnace from the volume and density of waste fed into the hopper.
