Target stereoscopic positioning is a significant sign of intelligent robot. The paper first described the research status of harvesting robot target stereoscopic positioning, discussed senor and stereoscopic positioning applications. Then, method and algorithm of rapid identification in target image were stated. In addition, version positioning, mechanism positioning, comprehensive positioning, associated positioning error, random positioning systematic error and application and existing problem of robot were introduced in this paper. Finally, harvesting robot positioning error compensation was proposed with the aiming at realizing robot precision positioning and expecting a great prospect of intelligent harvesting robot.
