In this study, an image processing based volume measurement system is presented. The proposed scheme provides high accuracy, low cost and ease of calibration. There a re n o additional requirements such as alignment of objects during measurement, positioning the objects at a certain position in the measuring field, and these advantages reduce the labor effort in real-time. In the first stage, a problem-specific calibration process was performed and then Hough transform was applied in the image processing phase. Although the proposed method has been developed primarily to measure the volume of box-type objects, it also provides an approximate volume measurement for objects of random geometry. The system tested under various external disturbances has produced satisfactory results.
