chaLYNX
Computer vision system for recognising plants and their developmental physiology and phenotypic characteristics
Overview
The computer vision system chaLYNX can be used in the agricultural sector for the intelligent detection of plants and their condition in real time in outdoor areas. It consists of a lighting unit, a camera module and a remote, high-performance processing unit. The remote processing unit can therefore be installed at a different location and is therefore ideally protected against harsh environmental influences or theft.
The chaLYNX system can be used to automate new processes in plant cultivation, such as selective plant protection or harvesting work. The processing unit of the chaLYNX system can be easily trained with new image data for the respective application and put to practical use in the shortest possible time.
Description
The sensor system consists of a unit for shading the ambient light. Inside, there are LED light modules, which are mainly used to optimally expose plants for image capture under homogeneous conditions, regardless of the time of day.
Each sensor unit is equipped with the appropriate high-power LED light modules for the application, which illuminate the surface with an illuminance of at least 50,000 lux. The illuminance refers to a uniformly illuminated area of approx. one square metre, taking into account a distance between the surface and the light modules of approx. 80 cm. The light spectrum and colour temperature can be adjusted as required. Exposure is synchronised with the image capture, or only as soon as an image is captured. In addition, the individual lighting units can be addressed in segments directly by the processing unit via CAN. This allows the light intensity to be configured, for example.
The sensor system is installed in a protected housing with cooling and has an automatic lens cleaning system. Image data is transferred from the camera to the processing unit using the robust GMSL high-speed data transfer method. One processing unit can process the image data from up to two sensor systems.
Fields of application:
-Detection of the growth centre of a plant
-Disease and pest detection
-Recognising the fruit and assessing the size, degree of ripeness and potential harvest yield
-Segmentation of objects
