Study of Theory for Video Identify of Knots on Log Based on Mathematics Model
基于数学模型的原木节子视频识别理论研究

This paper discusses the video measuring method for knot on the log. It puts forward the mathematics model of video characteristics and inside distribution of knot. We get the parameters of shape characteristics of knot through the processing of revising, strengthening and edge measuring for the image of knot. We simulate three-dimension image of knot using mathe- matics model, and then realize the computer simulation and localization of knot. It provides the basically theory and the video measuring technology for rejecting knot automatically and avoiding knot to make the localization of sawing optimally in log processing. And provides the concrete method for the programming of numerical control system in wood production as well. It realizes the video reproduction of distribution and form of knot on the log so that we achieve the goal of studying the space form and the distribution law of knot on the log.
