## Abstract

A stereo image scanning device includes a surround slide rail, an extending arm, at least one image capturing unit and an image processing unit. The surround slide rail is used to surround an object that is located at a geometric center of the surround slide rail. Two ends of the extending arm are connected to the surround slide rail and slid among multiple different scanning positions on the surround slide rail. The at least one image capturing unit is disposed at the extending arm, and the at least one image capturing unit is used to capture multiple images of the object at different multiple angle positions on the extending arm. The image processing unit is electrically connected to the at least one image capturing unit, and the image processing unit is used to receive and process the multiple images, so as to produce a stereo image of the object.

## Claims

### Claim 1

A stereo image scanning device comprising:
a surround slide rail to surround an object that is located at a geometric center of the surround slide rail;
an extending arm having two ends that are connected to the surround slide rail and slid among multiple different scanning positions on the surround slide rail;
at least one image capturing unit disposed at the extending arm to capture multiple images of the object at different multiple angle positions on the extending arm; and
an image processing unit electrically connected to the at least one image capturing unit to receive and process the multiple images, so as to produce a stereo image of the object.

### Claim 2 (depends on 1)
