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.
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.
The Phenospex 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.

Off the shelf products used in industry applications can barely match up with the requirements of scientists. In plant biology especially, where the object of interest is a living organism, looking for matching technology can become a tough journey. Phenospex‘s PlantEye is the first Laser Scanner that was specially designed and manufactured for plant screening applications.
Plants with complex architecture where leaves are overlapping can be challenging for screening leaf area and other parameters accurately. Therefore, PlantEye can be used in a so called DualScan mode. Using two PlantEye F400 that look at the plants from different angles we can acquire improved 3D point clouds for almost every species.
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, recognises plant organs and computes a diverse set of morphological plant parameters within less than a second.
PlantEye is manufactured to follow the IP65 standard and is therefore completely dust resistant and protected against any form of precipitation. The massive aluminium backplate works as a passive cooler and allows us to operate in high temperature environments. Active Peltier Elements will control the laser temperature and therefore always keep our needed laser wavelength. Since data is transferred via Wi-Fi, PlantEye only needs a power supply to operate. An external trigger allows additional flexibility when using PlantEye on carrier systems.
