Development of mobile RoboVision with stereo camera for automatic crop growth monitoring in plant factory

Plant Factory is a large-scale vegetable production method with limited, closed, and controlled space. This system is endeavored to support the sustainability of agricultural production system by applying the concept of precision agriculture. This concept is implemented to observe plant growth effectively and efficiently. Currently, in the conventional way monitoring carried out one by one, using the computer vision technology will help accelerate plant growth monitoring in the Plant Factory. However, in the application in a Plant Factory, it requires many cameras to be used for growth monitoring for each crop to support the precise measurement. So, it is necessary to have a system that supports the mobility of the camera module inside the plant factory. The objective of this study was to design the Mobile RoboVision using the stereo camera for automatic Crop Growth Monitoring. The system consists of three modules: stereo camera positioning system using M1 Computer Numerical Control (1000mm x 1000mm of size) equipped with x and y motor for flexible movement; Image acquisition system using Raspberry Pi B+ as microcomputer unit installed Stereo Camera standard with quad IR Illuminator and sensors; Data collection system using Cloud Storage. The camera positioning system manages the position of the camera module to stop in every crop in specified coordinate C1…n = {(x1, y1), (x2, y2), …(xn, yn)} and capture stereo images automatically. The captured image will be managed in a data collection system using Cloud System to provide flexible and convenient access for further analysis.Plant Factory is a large-scale vegetable production method with limited, closed, and controlled space.
