Particularly, FPGA can carry out image procossing and clock process to raster image control signal, it is the product further developed on the basis of the programming device such as PAL (PhaseAlteration Line), GAL, CPLD, occur as a kind of semi-custom circuit in application-specific integrated circuit (ASIC) (ASIC) field, both solve the deficiency of custom circuit, overcome again the shortcoming that original programming device gate circuit number is limited.Particularly, image controller 20, according to graphics control signals, determines image type image to be projected, controls the frame per second of raster image transmission and the time of transmission.By the use of FPGA, make the frame per second sending raster image controlled, the concrete time of transmission is controlled, is conducive to more reasonably allocating co-ordination between the projection of raster image control signal and image acquisition device 50; Significantly improve the frame per second sending raster image, the theoretical frame per second supported can reach 2K fps, and namely transmitted raster image per second can reach 2K frame.
Raster image control signal after FPGA process is sent to projecting apparatus 30 by DLP (process of Digital Light Procession digital light).DLP unit carries out optical digital computing to raster image, wherein uses crucial element DMD (Digital Micromirror Device digital micromirror elements).DMD arranges a matrix be made up of micromirror (accurate, miniature speculum) on a semiconductor die, each micromirror controls a pixel in projected picture, basically, the angle of micromirror only has two states: "ON" and "Off".The frequency that micromirror switches between two states can change, and this light that DMD is reflected presents the various gray scales between black (micromirror is in "Off" state) and white (micromirror is in "On" state).Raster image control signal after editting, after reception raster image control signal, is obtained raster image control signal through digital light process by DLP unit, and raster image control signal is sent to projecting apparatus 30 projects.
Scanner 1 disclosed in this invention, in another embodiment, scanner 1 comprises projecting apparatus 30, image acquisition device 50, recombination module 60, memory 70, generation module 90 and main control module 10.Projecting apparatus 30 pairs of scanned objects 40 project, the image that image acquisition device 50 pairs of scanned object 40 surfaces are reflected gathers, and the image of collection is sent to recombination module 60, the pixel of recombination module 60 pairs of images carries out layout restructuring and obtains target pixel points, and by object pixel point cache to preset memory 70, generation module 90 obtains target pixel points from memory 70, by object pixel dot generation three-dimensional plate, and three-dimensional plate is sent to main control module 10.Main control module 10 receives three-dimensional plate, and three-dimensional plate is spliced into the threedimensional model of scanned object 40.Projecting apparatus 30, image acquisition device 50, generation module 90 and recombination module 60 are all electrically connected with main control module 10.
Particularly, in the present embodiment, the work of object pixel dot generation three-dimensional plate has been come by generation module 90, and it is arranged independent of main control module 10.Generation module 90 comprises acquiring unit 92, generation unit 93, and the second control unit 91, and acquiring unit 92 and generation unit 93 are all electrically connected with the second control unit 91, and the second control unit 91 is electrically connected with main control module 10.Acquiring unit 92 obtains target pixel points according to the instruction of the second control unit 91, and the target pixel points of acquisition is sent to generation unit 93, and three-dimensional plate by object pixel dot generation three-dimensional plate, and is transferred to main control module 10 by generation unit 93.In actual use, the preferred DSP of function (the digital signal processor of generation module 90, digital signal processor) module realizes, and target pixel points, because of its powerful calculation function, can be generated the three-dimensional plate of scanned object 40 by DSP at short notice accurately.In the present embodiment, main control module 10 comprises main control unit 11 and concatenation unit 12, and main control unit 11 and concatenation unit 12 are electrically connected.Concatenation unit 12 receives three-dimensional plate, and three-dimensional plate is spliced into the threedimensional model of scanned object 40.
Introduce concatenation unit 12 below how the three-dimensional plate of acquisition to be spliced.
The scan mode of spatial digitizer 1 is subregion scanning, namely a certain region on scanned object 40 surface is scanned, again adjacent region is scanned, for convenience of description, a certain region is ordered for first area, adjacent region is second area, and first area and second area exist the region overlapped, overlapping region area occupied be first area 5% to 30% between; The image that first area reflects is the first image, is the first three-dimensional plate according to the contour structures of the first video generation, and the image that second area reflects is the second image, is the second three-dimensional plate according to the contour structures of the second video generation.
When main control module 10 receives the first three-dimensional plate of first area, first three-dimensional plate is added on the contour structures generated, if the first time scanning that the first three-dimensional plate is scanned object 40 is generated, so just the first three-dimensional plate is set to default position, waits for the second three-dimensional plate and its combination.After obtaining the second three-dimensional plate, the second three-dimensional plate is added on the first three-dimensional plate.Concrete adding method is as follows, owing to there is overlapping region between first area and second area, then certainly exists the identical region of shape between the first three-dimensional plate and the second three-dimensional plate.In the first three-dimensional plate and the second three-dimensional plate same area separately, find out three corresponding anchor points, three anchor points are not on the same line.The part that first three-dimensional plate is identical with the second three-dimensional plate shape superposes, in additive process, with selected three points for benchmark.When the anchor point of correspondence overlaps, the area coincidence that the first three-dimensional plate is identical with the second three-dimensional plate shape.Other region on scanned object 40 surface the like scanned and superposed, finally form the threedimensional model of a complete scanned object 40.
