3D Stereo Vision Measurements for Weed-Crop Discrimination

摘要

Computer vision research is targeting toward agricultural robotics applications. Our vision system contains two web cameras forming a binocular stereo-vision system. The weed-crop discrimination process is based on 3D stereo vision plant height measurements. A distance threshold can filter the plant which can be analyzed with respect to their height and colour [1]. The stereo vision system allows obtaining simultaneous information about colour and distance. The stereoscopic technique has been used by several researchers in the field of automation in agriculture [2-5]. Fig. 1 shows the plant arrangement used in our experiment for 3D stereo vision measurements.
