The invention relates to a wood automatic supervision method and a system which combines a laser contour detection, a machine vision recognition and an image processing technology, scans wood contour line for a laser scanning device used for train to transporting wood to gain cross section area of loading wood, uses a machine vision device to gain carriage length of the train, automatically gains volume of the loading wood. The invention also provides an automatic supervision method for yard logs or vehicle loading logs which process to scan for head faces of the logs, gain the cross section area of each log according to a head face image, and then try to obtain log volume according to the wood length, so as to realize the wood automatic supervision. The method and the system provided by the invention are applied to the customs, so as to reduce artificial examination strength of the customs system, improve examination accuracy, and effectively attack smuggling crime.
