Design and Operation of an Imaging Sensor for Detecting Vegetation

摘要

There is a need to sense vegetation form ground-based vehicles so that plants can be treated in a selective way, thus saving on crop treatment measures. This paper introduces a sensor for detecting vegetation under natural illumination that uses three filters, red, green and near infra-red (NIR), which a monochrome change couple device (CCD) camera. The sensor design and the data han- dling are based on the physics of illumination, reflection form the vegetation, transmission through the filters, and interception at the CCD.
