ABSTRACT:
New method for Image reproduction and recording is based on mechanical-guiding-apparatus-free operating methods, with flexible operations (hand, robot, vehicle), with the means for positioning, processing and controlling, and having exclusive plurality of uses. The system for image reproduction and recording based on this method includes these common apparatuses: head carrier, sprayer/reader or sprayer/reader array, and computer. Additional apparatuses used in wave-based positioning methods or relative-motion-based positioning methods, include operation-unit (OU) and communication-units (CU's), or operation-module (OM) and motion-detectors (MD), or respectively. The MD and OM provide the information of positioning for computer to determines the relative position and direction of the head array on head carrier. The CU's radiate and receive signal needed for determining distance information. The OU processes and converts the received signal into distance-related data and pass to computer. The computer determines the coordinates of each head in the head array from these data, and sends it back to OU or OM. Then the OU or OM sends the color data and spraying commands to head array, and provides power for head, or sends reading commands to head array for reading color data.
