Research progress of intelligent mechanized tea picking technology and equipment
In order to realize intelligent mechanized tea picking,increase production increase,save cost,increase market competitiveness and meet the development needs of digital agriculture and rural areas,the key technologies limiting the development of tea picking machinery and equipment such as end-effector,detection and positioning and picking sequence planning were summarized,and the research status was described and analyzed.The current outstanding research achievements in the field of intelligent mechanized tea picking were summarized.At present,due to the unstructured nature of the tea garden environment,the real-time performance of the end effector was low,the accuracy of the detection and positioning algorithm was greatly affected by nonlinear illumination changes,and the real-time performance of the global optimization of the tea picking sequence planning algorithm was poor.Suggestions were put forward for the development of intelligent mechanized tea picking equipment with low damage and high efficiency,such as the development of cut-collection integrated end-effector,the study of small-target accurate detection algorithm integrating multi-scale features,the design of multi-arm coherent picking sequence planning method,and the promotion of the combination of agricultural machinery and agronomy,so as to provide reference for promoting the research and popularization of intelligent mechanized tea picking equipment in China.
