Abstract:
An apparatus for producing 3D point-cloud model of physical objects includes a rotatable platform ( 11 ), multiple patterns asymmetrically arranged on the rotatable platform ( 11 ), a background curtain ( 13 ), and an image capturing unit ( 12 ) arranged facing toward the background curtain ( 13 ). A producing method includes: placing an object ( 2 ) to be scanned on the rotatable platform ( 11 ); setting a capturing amount during one-time rotation operation; controlling the rotatable platform ( 11 ) to perform the rotation operation, and controlling the image capturing unit ( 12 ) to capture corresponding images during the rotation operation according to the capturing amount, wherein each image includes the entire object ( 2 ) and multiple of the patterns, and records corresponding global coordinates; and, performing matching on multiple features of each of the images, and constructing a 3D point-cloud model of the object ( 2 ) according to a matching result of the features and the global coordinates of each of the images.

Claim (Index 15):
The method in  claim 8 , wherein the producing apparatus ( 1 ) further comprises a second image capturing unit ( 15 ), electrically connected with the microprocessor ( 10 ) and arranged aiming at the background curtain ( 13 ), wherein the second image capturing unit ( 15 ) is arranged with a height and an angle different from that of the image capturing unit ( 12 ), and the second image capturing unit ( 15 ) is set with the capturing amount same as the image capturing unit ( 12 ), and the method further comprises following steps before step a):\n a1) controlling the rotatable platform ( 11 ) to perform the rotation operation and controlling the image capturing unit ( 12 ) and the second image capturing unit ( 15 ) to capture an alignment picture on the rotatable platform ( 11 ) for generating multiple alignment images during the rotation operation, wherein each of the multiple alignment images respectively contains the entire alignment picture; a2) retrieving multiple records of intersection position information of each of the multiple alignment images respectively; a3) performing a matching action on the multiple records of intersection position information of each two alignment images of the multiple alignment images; a4) performing a regression calculation according to a matching result of the matching action for estimating relative positions between the image capturing unit ( 12 ) and the second image capturing unit ( 15 ); a5) calculating an average height difference according to a result of the regression calculation for obtaining a height difference of the image capturing unit ( 12 ) and the second image capturing unit ( 15 ); a6) applying the result of the regression calculation to a circle equation for estimating a rotating radius; and a7) utilizing a center of the rotatable platform ( 11 ) as a zero point and estimating actual relative positions of the image capturing unit ( 12 ) and the second image capturing unit ( 15 ) according to the height difference and the rotating radius.
