CanopyAIxpert the multi-camera sensor to plant phenotyping system for glasshouses, growth rooms, climate chambers, cultivation halls, or indoor farms.

The automated high-throughput CanopyAIxpert combines rapid automated data recording with advanced analytical software and machine learning. LemnaTec is the global specialist for automated CanopyAIxpert Solutions that not only save time and labour, but also provide a much broader base of information compared to visual scoring. The CanopyAIxpert technology is dedicated to users who work with ground-standing plants – directly in soil, in containers, or pots – that are not movable, or not intended to move. The sensor-to-plant system records imaging data from above the plants, and usually delivers data on plant canopies rather than on individual plants.

  • Sensor to plant
  • Dedicated optics and illumination
  • Fixed plant positions
  • Broad range of imaging and sensing modules
  • Available for a range of dimensions
  • Sensors mounted on gantry structure that moves across plant area

We recommend recording environmental data in the plant growth area, such as temperature, light, or air humidity. We offer recording systems that store the environmental data together with the phenotypic data of the corresponding plants.

Application examples

Canopy-level plant imaging and analysis

Ground-standing plants – here wheat – were imaged with an RGB camera and the image was processed for counting ears. The information is not gained per individual plant but as canopy data, i.e. as target objects per area.

Fluorescence imaging at canopy level

A canopy consisting of wheat leaves was imaged for chlorophyll fluorescence that is indicative of the physiological status of the plants and can serve to detect stress- and pathogen- induced damages

Thermographic image (infrared image) of a plant canopy

Infrared imaging allows quantifying heat emission from plant surfaces and thereby indicates plant temperatures.

Vegetation density imaging

Plant canopy imaging with an RGB camera can be processed to determine vegetation cover and plant density per ground area.

Modular Building Set with Three Application-Oriented Designs

The LemnaTec CanopyAIxpert is available in three models and can easily be customised to your needs.

X-Z Moving Carrier System

Model type 1 is a system for non-scanning cameras mounted in fixed positions on the carrier system. It moves along the plant rows (X-direction) and the cameras can be height-adjusted (Z-direction). As there is one camera system above each row, no Y-directional movement is foreseen.

  • Carrier system installed on adjustable framework in greenhouse
  • Top-down working method
  • Moveable X-Axis based on timing belt drive
  • Length up to 25 m
  • Suitable for non-scanning cameras (e.g., RGB, IR)
  • Y-Axis up to 8 m length
  • Z-Axis up to 2 m length (height adjustment optional)

X-Y-Z Moving Carrier System

Model type 2 is a system for scanning and non-scanning cameras mounted as exchangeable sensors on the carrier system. It works in combination with the LemnaTec Sensor Exchange Station System. The system has an adjustable Z-axis for different sensor types and different plant heights. The sensor and the Y-axis are moved together in Z-direction to adjust imaging height and prevent collisions with taller plants. The measuring head with the sensor moves along the Y-axis across the plant rows. The Y- and Z-axes travel along the plant rows in X-direction. In model type 2, mainly dedicated for glasshouses, the X-axes are mounted onto stands that are placed next to the planting area.

  • Carrier system installed on adjustable framework in greenhouse
  • Top-down working method
  • X-Y-Z-Gantry system based on linear axes
  • X-Axis up to 8.5 m length
  • Y-Axis up to 8 m length
  • Z-Axis up to 2 m length
  • Suitable for static and scanning sensors (e.g., RGB, IR, hyperspectral cameras, 3D laser scanner …)
  • Sensor exchange station optional for fully automated operation with different cameras/sensors

Compact X-Y-Z Moving Carrier System for Climate Chambers

Model type 3 is a system for scanning and non-scanning cameras mounted as exchangeable sensors on the carrier system. It works in combination with the LemnaTec Sensor Exchange Station System. It is a compact system that particularly fits into climate-controlled chambers. Axis movements are equivalent to model type 2. In model type 3, mainly dedicated for climate rooms, the X-axes are mounted onto the walls of the room; if walls are not suitable for mounting, model type 2 with a floor-standing system can be used.

  • Carrier system installed on adjustable framework in greenhouse
  • Top-down working method
  • Suitable for climate-controlled chambers
  • X-Y-Z-Gantry system based on linear axes
  • X-Axis up to 8.5 m length
  • X-Axis for wall mount or on pillars
  • Y-Axis up to 8 m length
  • Z-Axis up to 2 m length
  • Suitable for static and scanning sensors (e.g., RGB, IR, hyperspectral cameras, 3D laser scanner …)
  • Sensor exchange station optional for fully automated operation with different cameras/sensors

Software

The CanopyAIxpert is delivered with a comprehensive software package. The software provides all possibilities of system control so that users can provide sample information and program a complete workflow for the samples. Users can define the samples loaded into the system, and give information such as species, genotype, treatment, or other grouping parameters. For all available cameras, users can determine which imaging principles are used with the loaded samples – full set or selected sub-set – and make the essential settings such as exposure, white balance, and more.

After imaging all data are stored and accessible for image and data processing. With LemnaGrid, we provide a userprogrammable image processing toolbox that allows for analyzing the recorded image data. LemnaGrid comprises a large library of functions to handle, analyze, and process various types of image data. By combining functions on a graphical surface, users can establish analytical workflows. In addition, we offer the development of customized analyses for user-generated images, including machine learning procedures.

The LemnaAIxplorer enables access to and visualization of all images, analyses, and related data. Tabulating and plotting functions are available together with image browsing. All data can be exported as CSV files or directly delivered to standard data bases.
