The invention relates to a quickly self-feedback scanning system and a method for controlling the quickly self-feedback scanning system. The quickly self-feedback scanning system comprises a computer, a projector controlling device and scanning equipment provided with a projector and two cameras, wherein the projector controlling device comprises a central processing unit, and an Ethernet interface unit, an input and output interface unit and a video graphics array (VGA) drive unit which are connected with the central processing unit; the Ethernet interface unit is connected with the computer; the input and output interface unit is connected with the cameras; and the VGA drive unit is connected with the projector. The method for controlling the quickly self-feedback scanning system comprises the following steps that: the projector controlling device receives a command of the computer, and sends raster image information to the projector, the projector controlling device acquires an external triggering enabling signal of the cameras, and triggers the cameras to take photos; and the computer reads images which are shot by the cameras after exposure of the cameras. Raster data are not required to be written for a video card of the computer, the computer can effectively process the data obtained from the cameras, the scanning speed is high, the scanning effect is good, and the working efficiency is improved greatly.
Description
technical field [0001] The invention relates to a scanning system, in particular to a fast self-feedback scanning system and a control method. Background technique [0002] At present, when the scanning device scans, it only needs to be connected to a computer, wherein the graphics card in the computer is connected to the projector in the scanning device, and the two cameras in the scanning device are connected to the computer. The scanning process is: the computer writes the projection raster information into the graphics card, and the graphics card then controls the projector to project the raster. The projector cannot update the projection raster immediately due to the hysteresis characteristic. The computer must wait for a while to confirm that the projection is completed, and then collect two For the photo data of the camera, since the feedback signal of the camera cannot be detected, the computer must wait for the photo transmission of the two cameras to be completed b...
