On the self-movement of camera 2, and the direction of motion of camera 2 be perpendicular to the direction of the table top of the workbench 1, all straight lines
Module 3 is equally distributed on the semi arch centered on workbench 1.
Three dimensional vision modeling method is：The object for needing to carry out three dimensional vision modeling is placed on the table top of workbench 1,
More cameras 2 move up and down relative to object under the driving of respective straight line module 3 and carry out image scanning, what camera 2 scanned
Image transmitting to host computer, host computer carries out feature extraction, synthesis to the image of multiple cameras 2 and modeled.Because camera 2 is distributed
On the semi arch centered on workbench 1, therefore phase unit can only scan its half of side to the single sweep operation of object,
Scan through behind half of side of object, it is necessary to object is turned round into 180 degree, its other half of side is scanned to complete object
Entire scan and modeling.
The above-mentioned method that object is turned round to 180 degree can be that object manually is rotated into 180 degree relative to workbench 1,
It is preferred that workbench 1 is arranged into rotatable form relative to ground, can be not required to when so being turned round to object
Become position of the animal body relative to workbench 1, modeling result is more accurate, and further, workbench 1 is driven back by motor
Turn, to ensure that angle of revolution is accurate.
As shown in Figure 4, straight line module 3 includes module frame 31 (module frame 31 is industrial aluminum profile in the present embodiment), mould
The drive component that can be moved with respect to the sliding unit 32 and driving sliding unit 32 of its slip, the phase are installed on group frame 31
Machine 2 is arranged on the sliding unit 32.The drive component include being separately positioned on the driving wheel 33 at the both ends of module frame 31 with
Driven pulley 34, the timing belt 35 engaged respectively with both is provided between driving wheel 33 and driven pulley 34, driving wheel 33 is by driving
The driving of motor 36 rotates.
