A method includes constructing a three-dimensional model of a front side of a row of trees based on a plurality of images of the front side of the row of trees and constructing a three-dimensional model of a back side of the row of trees based on a plurality of images of the back side of the row of trees. The three-dimensional model of the front side of the row of trees is merged with the three-dimensional model of the back side of the row of trees by linking a trunk in the three-dimensional model of the front side to a trunk in the three-dimensional model of the back side to form a merged three-dimensional model of the row of trees. The merged three-dimensional model of the row of trees is used to determine a physical attribute of the row of trees.

Semantic structure from motion for orchard reconstruction

A method of machine vision includes identifying contours of fruits in a first image and a second image and performing two-way matching of contours to identify pairs of matched contours, each pair comprising a respective first contour in the first image that matches a respective second contour in the second image. For each pair of matched contours, a respective affine transformation that transforms points in the respective second contour to points in the respective first contour is identified. The second image is mapped to the first image using the affine transformations to form a composite image and the number of fruits in the composite image is counted.
