100x the resolution satellites give you, read by a model that knows the crop

resolution vs satellite

Satellite imagery at 40 cm is useless for precision agriculture. Psyche AI flies the field at 4 cm across RGB, NIR, NDVI, and DVI and runs a crop-specific model that detects, outlines, and counts.

The challenge

The default in crop monitoring is satellite imagery at roughly 40 cm resolution. At that scale a pest outbreak, a stand-count gap, or early disease stress does not exist. A pixel covers several plants. Growers see the problem when it is already visible from the road, then spray the whole field.

The economic gap is real and measurable: the difference between the average grower and the regional efficient frontier, in yield lost to pests, disease, and stress, plus inputs applied where they were not needed.

What they needed
  • Resolution fine enough to see an individual plant
  • More than RGB: vegetation indices that expose stress before the eye can
  • Crop-specific models: soy does not look like sugarcane
  • An output a farm manager acts on this week, not a heatmap for the office wall
  • An economic case they could defend to a CFO before committing to a season

The brief was visual. Separate the plant from the weed. Then count. Then say which hectares to walk this week.

Goals & success metrics
  • 4 cm capture across the full property
  • Plant-level detection and counting against ground truth
  • Localized / variable-rate treatment instead of spraying the whole field
How we did it
  1. 01

    Capture

    Drone flights at 4 cm ground resolution with a multispectral payload; the same location captured across RGB, NIR, NDVI, and DVI in a single pass.

    Four-panel capture of the same rows in natural color, vegetation index, high-contrast biomass, and a cool spectral band.
    Fig. 08. One pass, four reads: natural color, vegetation index, high-contrast biomass, and a cool band for water stress. RGB is the least of it.
  2. 02

    Detection

    Crop-specific models detect and contour individual plants, count stands, and map stress by zone. Each output is tied to the crop's phenological stage, because the same anomaly means different things at emergence and at flowering.

    Instance segmentation of plants as colored masks with a red centroid on each detection.
    Fig. 09. Instance masks and centroids on every plant. Contour first, then count. The model is looking at organisms, not pixels.
    Split view of close plant masks with centroids and a wide pass where each plant has a numeric ID.
    Fig. 10. The same method at two scales: a close row where each plant is a mask, and a wide pass where each plant is an ID.
    Processed grayscale scan of a triangular field with color-ranked bounding boxes and a confidence scale.
    Fig. 11. Zone-level ranking on a processed scan. Color is priority, not decoration. One box at the top of the scale is the hectare to walk first.
    Three-step weed versus crop pipeline: raw plants, labeled bounding boxes with confidence, and a red-green action mask.
    Fig. 12. Capture, classify, act. Bounding boxes name crop versus weed. The mask on the right is what a sprayer would follow.

    Decision layer

    Results are delivered as a prioritized list: which hectares, which issue, which window, rather than an image.

    Property-scale vegetation index map with rectangular fields, center-pivot circles, and a winding watercourse.
    Fig. 14. A vegetation index the manager can defend in the operations meeting: which blocks are performing, which are not, at the scale of the property.
  4. 04

    Economic model

    A per-crop, per-region opportunity model calibrated on public agronomic baselines (CONAB, Embrapa, regional producer data), with a ±20% confidence band declared upfront. The same model powers the public calculator on the product page.

    Tilted vegetation-index map with stacked semi-transparent data layers behind the terrain.
    Fig. 15. The same terrain as stacked layers: spectral bands and history, not a single snapshot. This is what the opportunity model reads before it talks to a CFO.
