文摘
- •
Stems and calyxes were recognised using computer vision and structured lighting.
- •
3D height of the apples was constructed.
- •
Standard spherical models were also automatically constructed.
- •
A simple ratio algorithm was developed to recognise the stems and calyxes.
- •
The system and methods could be reproduced using low cost cameras.
