Method for autonomously scanning and constructing a representation of a stand of trees

A method comprising:

• accessing an overhead image depicting a stand of trees;
• accessing a set of ground images representing bases of the stand of trees and captured by a vehicle;
• isolating a first set of trees, in the stand of trees, depicted in the set of ground images;
• for each tree in the first set of trees:
• detecting a first region of the set of ground images depicting the tree;
• extracting a first set of visual features from the first region of the set of ground images;
• characterizing a first value of a metric of the tree based on the first set of visual features;
• detecting a second region of the overhead image depicting the tree;
• extracting a second set of visual features from the second region of the overhead image;
• calculating a confidence score of the first value of metric of the tree proportional to a resolution of the first region of the set of ground images depicting the tree;
• and
• storing the confidence score, the first value of the metric, and the second set of visual features in a container in a set of containers;
• isolating a second set of trees, in the stand of trees, excluded from the set of ground images;
• for each tree in the second set of trees:
• detecting a third region of the overhead image depicting the tree;
• extracting a third set of visual features from the third region of the overhead image;
• and
• characterizing a second value of the metric of the tree based on the third set of visual features;
• generating a virtual representation of confidence scores for the first set of trees;
• and
• compiling values of the metric, for the first set of trees and the second set of trees, into a composite value of the metric for the stand of trees annotated with the virtual representation of confidence scores.

• for each tree in the second set of trees:
• detecting a second image, in the set of overhead images, depicting the tree;
• extracting a third set of visual features from the second overhead image;
• and
• characterizing a second value of the metric of the tree based on the third set of visual features and the metric function;
• and
• compiling values of the metric, for the first set of trees and the second set of trees, into a composite value of the metric for the stand of trees.
