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 1):
An apparatus ( 1 ) for producing 3D point-cloud model of physical object, comprising:\n a rotatable platform ( 11 ), arranged to carry an object ( 2 ) to be scanned; multiple patterns, arranged asymmetrically on the rotatable platform ( 11 ); a background curtain ( 13 ), arranged at one side of the rotatable platform ( 11 ); an image capturing unit ( 12 ), arranged at other side of the rotatable platform ( 11 ) against the background curtain ( 13 ) and aiming at the background curtain ( 13 ); and a microprocessor ( 10 ), electrically connected with the rotatable platform ( 11 ) and the image capturing unit ( 12 ), configured to set a capturing amount of the image capturing unit ( 12 ) during one-time rotation operation of the rotatable platform ( 11 ); wherein, the microprocessor ( 10 ) is configured to receive a trigger action for controlling the rotatable platform ( 11 ) to perform the rotation operation and controlling the image capturing unit ( 12 ) to capture multiple images of the object ( 2 ) according to the capturing amount during the rotation operation, wherein each of the images respectively records the entire object ( 2 ) and the multiple patterns, and respectively records a set of global coordinates corresponding to different angle of view; wherein, the microprocessor ( 10 ) is configured to perform a matching action on multiple feature points of the object ( 2 ) and the multiple patterns of each of the images, and re-builds a 3D point-cloud model of the object ( 2 ) according to a matching result of the matching action and the sets of global coordinates of each of the images.
