Kind of guidance device for field vehicle based on embedded image processing

The feature of elevating transporter in bridging construction was analyzed. Aimed at the primary problem of vehicle′s guidance and on-site′s practical requirement, a new kind of auxiliary device for vehicle′s guidance based on embedded image processing using single chip microcomputer was developed. The relevant hardware platform was designed, and such key technologies in single chip microcomputer system as video acquisition, image processing, judgment of vehicle′s off tracking and output of alarm were introduced in detail. The results of experiments revealed that this device meeted the traveling requirement of the elevating transporter on the track-beam. The device was applied in field construction, and the method of design and implementation is well worthy for other large-scale field vehicle′s guidance.
