0.5mm。 An object locating method for strawberry-harvesting robot was proposed and evaluated in view of aimed at the “hill culture” planting pattern and characteristic of liable to damage for strawberry. The method includes two steps: “2-D information acquisition”, during which “mirror-image match method” is used to locate the strawberry’s fruit axis; “distance judgment between object and end-effector”, in which laser is used to assist distance judgment. The experiment results showed that the system is suitable for locating long-conical strawberries. The average time required for locating the picking position is 381 ms, the maximum measurement error of the distance is 1.6mm and the average error is 0.5mm.
