PlantEye – 3D Laser Scanner for Plants

PlantEye is a high-resolution 3D Laser Scanner specially designed for plant phenotyping in challenging environments. PlantEye follows the sensor-to-plant concept, allowing you to make assessments of plants growing in fields or in any other setting where plants cannot be moved. PlantEye is also fully sunlight resistant and temperature controlled and is fully operational in harsh and hot environments. Check also our Multispectral 3D Sanner PlantEye F500.

PlantEye automatically computes a diverse set of morphological plant parameters and provides raw information as 3D point clouds. It’s effective not only on dedicated sensor-to-plant platforms, where it’s able to screen thousands of plants per hour, but also on existing conveyor based phenotyping platforms, where it can easily be retrofit for use.

Why we developed PlantEye

Various 3D technologies are available on the market, however, none are fully capable of assessing plants in high resolution and in harsh and bright environments, which are key requirements for field phenotyping. Moreover, most 3D sensors deliver only 3D point clouds, leaving users with the challenge to derive meaningful parameters from large data sets. Our idea was to provide a sensor that can easily be integrated into screening routines, used under any environmental conditions, and which can also deliver morphological information quickly and efficiently. PlantEye was specially developed for plant phenotyping applications in breeding, science and production.

How it works

PlantEye uses a laser light section to acquire 3D point clouds of plants. It projects onto the plant or plant canopy a very thin near-infrared laser line, which is reflected and captured with an integrated camera that is mounted at the other end of the PlantEye sensor. The projected laser line shifts based on its distance towards the sensor, and a record of those shifts is then used to generate a height profile of the plant. By moving the sensor over the plant, or by moving the plant relative to the sensor, you get multiple height profiles which are merged together to form a 3D model of the plant. In a second step, the sensor segments this 3D model, recognizes plant organs and computes a diverse set of morphological plant parameters within less than a second.

Give technology a meaning

We think there is a little more to deliver in phenotyping than just technology. All our products are designed with the intent to deliver meaningful features and results to our clients.

Automated computation of plant parameters

Deriving parameters can be a challenge when using standard sensors that haven’t been developed for plant phenotyping. PlantEye automatically computes a diverse set of morphological plant parameters, such as height, 3D leaf area, projected leaf area, ground coverage, leaf area index, light penetration depth, digital biomass and leaf inclination — no computational skills are required. If the parameter that you are seeking to measure is not available, we are more than happy to work with you to develop new ones: we develop, you validate! All parameters are calculated in real time and on the sensor, with no need for complex and expensive server solutions.

How we can screen from Saudi Arabia to Norway

Phenotyping sensors have to perform under any conditions, as breeders and plant biologists cannot wait for the right conditions to arrive when they are phenotyping plants in the field. However, most optical sensors are simply unable to do this because of their susceptibility to sunlight and heat. PlantEye overcomes this common shortfall by fully conditioning and containing the phenotyping sensor in a protective sunlight filter, thus enabling phenotyping to occur under any environmental conditions and without any safety hazard for the users or plants, as demonstrated by Aarhus University. Its housing consists of a robust UV-proof POM case with a 10mm aluminium lid. All components are IP67 resistant to dust and precipitation.

Sensor-To-Plant Concept

In many cases, plants cannot be moved to imaging stations, either because they are growing in the field, or because movement would affect plant growth. It may also simply be the case that space or financial resources are not available for the installation of conveyor belt systems. Following the sensor-to-plant concept, PlantEye opens up a lot of new applications at a competitive cost and with a possible throughput of more than 5,000 plants/h. PlantEye is an autonomous sensor containing a high grade of intelligence and can be operated independently from any carrier device. This makes it easy to test the system or to integrate it into your phenotyping platform—it is even possible to integrate PlantEye into conveyor-based platforms. All data is transferred via Wi-Fi that can handle multiple sensors and environmental stations at the same time.

Open Platforms for seamless access

We all know how difficult or inconvenient it can be to access data from technical devices, especially when proprietary protocols are used. PlantEye is an open system that allows users to access RAW data or analyzed plant parameters at any level. Direct access to the embedded PlantEye computer can be set up with a public SSH protocol in order to download RAW data, point clouds or derived parameters. Data can also be stored in our HortControl database and accessed through a web interface from any computer or tablet in your network.

High resolution 3D measurements in metric numbers

PlantEye doesn’t provide cryptic data sets that have to be calibrated or recalculated. We provide data that is ready for interpretation. All of our 3D point clouds are calibrated. This means that leaf area is no longer measured in pixels as a 2D projection that varies distance and angle, but as a real area that is reported in millimeters. With a maximum resolution of up to 0.1 mm in height, PlantEye is able to measure even small plants, such as Arabidopsis, in very high precision. Our large-scale calibration can also measure mature corn plants from top to bottom. And the good thing is 1mm is always 1mm.
