Method and system for measuring single fruit tree yield

The invention discloses a method and a system for measuring a single fruit tree yield. Three-dimensional point cloud data of a fruit tree are obtained and are pre-processed to obtain a three-dimensional point cloud data set of the fruit tree; the three-dimensional point cloud data set of the fruit tree is divided to obtain a fruit three-dimensional point cloud data set which only comprises fruit information; statistics is carried on the fruit three-dimensional point cloud data set to obtain N fruit three-dimensional point cloud data subsets and the number of fruits N; the fruit radius of each corresponding fruit is calculated according to the fruit three-dimensional point cloud data subsets to obtain a fruit radius digit group; fruit weight corresponding to each fruit radius in the fruit radius digit group is calculated one by one according to basic parameters of a relation model of fruit radius and fruit weight, and the yield of the whole fruit tree is calculated through accumulation. The method and the system for measuring the single fruit tree yield are capable of measuring the single fruit tree yield accurately, quickly and harmlessly.
