摘要： Tree structure probing is a significant basic part of target precision spraying. Orchard tree structure digital test system, which consists of three components, is designed by using the ultrasonic sensors. The conveying platform is for fixing and precisely moving the sensor which is used for probing the tree profile. The lower computer can process the test data and communicate with upper computer. The upper computer can record data into Access database and show the results to the users at the same time. Utilizing the orchard tree structure digital test system, a Hawthorn tree structure is calculated. The experiment shows that probing accuracy is not less than 87%. (c) 2011 Published by Elsevier Ltd
