AGRICULTURAL MULTISPECTRAL IMAGING SYSTEM

The present invention relates to an agricultural multispectral imaging system, which comprises a camera, a rotating wheel, optical filters, a mounting platform and a 5 rotating wheel rotating mechanism, Wherein a plurality of optical filter holes are formed in the rotating wheel, the optical fibers with different wave bands are mounted on the optical fiber holes; and the camera and the rotating wheel rotating mechanism are mounted on the mounting platform. According to the present invention, the main shaft is rotated at a fixed angle under the combined action of a steering gear (which 10 can drive a main shaft to reciprocate) as well as a front support and a rear support (which are provided with single-bevel grooves and symmetrical V-shaped grooves), thereby accurately switching the optical filters. Compared with the structure of driving a rotary table to rotate at a fixed angle by a stepping motor, the steering engine is low in price and excellent in fault tolerance, so that the equipment is low in cost and 15 accurate in rotation.
