Data for: Multi-feature fusion tree trunk detection and orchard mobile robot localization using camera/ultrasonic sensors

1、The data files include sample images of the tree trunks and they are used to train trunk recognization classifier. 2、The localization data consist of angle and distance information in the files and the data were obtained by the mobile robot when it moving along the road in the orchard.The detection systems were used to measure the angle and distance between the mobile robot and tree trunks.
