How It Works
Five simple steps to accurate LAI measurements in the field.
Open the App
Launch Tamiatics on your smartphone. Works on iOS and Android.
Remove a Leaf
Take a single leaf from the plant and place it on a white background — a sheet of paper works perfectly. Each measurement uses one detached leaf.
Add the ArUco Marker
Place the printed 5x5 ArUco marker (50 × 50 mm) on the paper next to the leaf — it gives the AI an exact size reference. Print at 100% scale, do not fit to page.

Photograph the leaf and marker together against the white background. Keep both fully in frame — the AI does the rest.

What is Leaf Area Index?
Leaf Area Index (LAI) is a key indicator of plant health and growth. It measures the total one-sided area of leaf tissue per unit ground area. Higher LAI generally indicates more photosynthetic capacity and healthier crops.
Traditional LAI measurement requires expensive equipment or destructive sampling. Our mobile tool uses AI image analysis to provide minimal-impact, instant measurements using just your smartphone.
In practice: a grower checks LAI weekly to see if canopy development is on track for the growth stage. If LAI is lower than expected, it's an early signal to adjust nutrition or spacing — before it shows in yield.
