PlantEye - 3D Multispec plant scanner sensor

PlantEye multispectral 3D scanner for plants

PlantEye is a unique plant sensor that combines the strength of 3D vision with the power of multispectral imaging. It captures plants non-destructively and delivers precise and objective plant parameters in real time. 

    • Non-Invasive plant screening – No harvesting or moving
    • 17+ Plant parameters each scan – Morphological and Spectral plant parameters
    • All environments – Scan in direct sunlight, rain & rough conditions
    • Precise & Objective – Reproducible plant data
    • High throughput – Scan thousands of plants multiple times a day
    • Reduce costs – automate plant assessment 
    • Integrate in any system – gantries, conveyors, vehicles
    • Automation for indoor farms – 3D vision and big sets of plant data

For applications where detailed information or high numbers of plants are required. The PlantEye is built with high quality standards to operate in any environment like growth chambers, labs, greenhouses and fields.

Phenotyping automation, our process:

 

1. 3D & Spectral scan
 

PlantEye moves over your crops and captures them in 3D and with multispectral information 

The PlantEye moves over the plants to create our unique 3D Models. We combine  3D imaging with a multispectral flashing unit, that illuminates the plant and measures up to 4 wavelengths immediately after the 3D acquisition of the plant in high frequency. This way we can overlay 3D and multispectral information in one combined data set without the need for complex sensor fusion algorithms. Hence we provide both morphological and physiological parameters in one shot. 

  • 3D and Multispectral data combined
  • High precision
  • Independent of lighting conditions
  • Fully automated
  • High scan interval – Scan day and night

Many phenotyping devices require the plants to be moved. This is expensive, limits the throughput, impacts the plant and well, sometimes you just cannot move the plant as it grows in the soil. That is why we bring the sensor to the plant.

2. 3D Model
 

3D Plant Model is generated to calculate plant Parameters

A 3D model of your plant, tray, plot or even entire field is generated by PlantEye. The model  is stored as an open PLY format. The plant model  is built out of points called a 3D point cloud. Every point contains the following information:

  • x, y, z coordinates in space
  • Reflectance in Red, Green, Blue, and Near-Infrared
  • Reflectance of the 3D Laser (940nm)

The 3D model is stored and can be accessed in HortControl or any other 3D software. Raw data and computed plant parameters are available as open source files.  

From these 3D models we calculate all plant parameters needed for your research or your application in real time.

The spectral information from the 3D models enable us to calculate different spectral indices like NDVI or PSRI.  For example the NDVI model (below) allows us to calculate many parameters related to plant senescence like healthy and unhealthy foliage.

3. Plant Parameters
 

What plant parameters can we measure?

PlantEye automatically computes a wide variety of morphological parameters such as:

  • Plant Growth
  • Digital biomass
  • Plant height
  • Plant height max
  • 3D leaf area
  • Projected leaf area
  • Leaf inclination
  • Leaf area index
  • Leaf Angle
  • Light penetration depth

PlantEye measures the spectral reflectance of part of the plant. Each wavelength can be statistically analyzed individually to calculate and quantify:

  • Color
  • Greenness
  • Chlorophyll levels
  • Senescence
  • N-content

 Wavelengths can be combined into spectral indices. At the moment we can calculate the most important indices like:

  • Normalized Digital Vegetation Index (NDVI)
  • Normalized Pigments Chlorophyll ratio index (NPCI)
  • Plant Senescence Reflectance Index (PSRI)
  • More are developed continuously

4. Start Analyzing
 

Start Analyzing & Visualizing your data with HortControl

HortControl is the central software to setup your experiments and to store and manage your data locally on your site. Within seconds after the scan, the plant parameters sets can be visualized and analyzed with the HortControl tool box.

  • Set up and control experiments
  • Visualize, aggregate and export data
  • Automated reports e.g. germination report or growth report

HortControl is highly user friendly and designed to be used by staff with any professional background. You can access HortControl form your office or in the field. Read more >
