文摘
- •
Digital tree models are of interest in precision fruticulture/horticulture.
- •
We have reviewed Verroust and Lazarus reconstruction algorithms.
- •
A dual neighbourhood graph is proposed to reduce occlusion problems in point clouds.
- •
Vegetative indices have been obtained and tested.
- •
Results of the algorithm could be used to monitor and quantify pruning operations.
