Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
As shown in figure 1, the utility model embodiment proposes a kind of material scanning system, including at least two line-scan digital cameras
1st, camera trigger device 2 and image processing apparatus 3；
The focus of at least two line-scan digital cameras 1 is co-located, and at least two line-scan digital cameras 1 are respectively arranged with counter
101, counter is provided with counting mechanism 1011, frequency divider 1012 and camera trigger mechanism 1013；
Camera trigger device 2 includes signal-sending mechanism 201, the line-scan digital camera 1 of signal-sending mechanism 201 and at least two
Counter 101 communicates to connect；
Image processing apparatus 3 communicates to connect with least two line-scan digital cameras 1.
It can be seen that material scanning system and color selector that the utility model embodiment proposes, the meter of at least two line-scan digital cameras
Number device receives the trigger signal of camera trigger device, and frequency divider divides to trigger signal, the trigger signal triggering after frequency dividing
At least two line-scan digital cameras, the view data that at least two linear camera output phases stagger, image procossing mechanism, which receives, to be merged
The view data of the phase shifting of at least two cameras output, so as to obtain the scanning figure higher than at least two camera line frequencies
Picture, the camera without changing high line frequency can just improve the sweep speed of material and the efficiency of separation of material.
Wherein, the focus of at least two line-scan digital cameras is located at material to be scanned, and image processing apparatus is color sorting plate.
In a preferred embodiment of the present utility model, camera trigger device also includes high level transmitting mechanism, high electricity
Flat transmitting mechanism connects the counter of at least two line-scan digital cameras.
Specifically, high level is used for initializing camera counter.When carrying out camera triggering, enter the first of linage-counter in advance
After beginningization, the technology of counter can be made more accurate.
For example, when counter is for carrying out odd number rising edge triggering line-scan digital camera, if counter is not pre-
First initialize, easily cause counting inaccuracy, odevity is chaotic, influences to count.
In a preferred embodiment of the present utility model, camera trigger device is driving plate.
