<p>An apparatus (1) has a light-sealing enclosure (2) which is drawn over vegetation on sleigh-like light seals (15). The vegetation within the enclosure is conditioned by a roller (6). Conditioned vegetation is illuminated in a transverse line by a set of four laser emitters (20) and corresponding cameras (21) capture images. These images are processed by analysis of height and texture data to identify weeds. A weedkiller dispenser (30) selectively sprays weeds according to the image processing output. A seed dispenser (35) selectively dispenses seed in the sprayed area to ensure desired vegetation takes over the affected area. <IMAGE></p> |
