Virtual image display device and stereoscopic image establishing method
A virtual image display device and a stereoscopic image establishing method are provided. The virtual image display device includes a head-mounted display and an accessory. The head-mounted display performs an image capturing operation on a first region of an object to obtain first image information. The accessory has a first image capturing device for performing an image capturing operation on a second region of the object to obtain second image information. The head-mounted display establishes stereoscopic image information of the object based on the first image information and the second image information.
1 . A virtual image display device, comprising:
a head-mounted display, configured to perform an image capturing operation on a first region of an object to obtain first image information; an accessory, having a first image capturing device, and configured to perform an image capturing operation on a second region of the object to obtain second image information, wherein the first image information is a first image, the second image information is point cloud information,
wherein the head-mounted display establishes stereoscopic image information of the object based on the first image information and the second image information and combines the first image and the point cloud information to generate the stereoscopic image information, and
respectively matches a plurality of first feature points on the first image and a plurality of second feature points on the point cloud information based on an overlapping portion of the first image information and the second image information to combine the first image and the point cloud information.
2 . The virtual image display device as claimed in claim 1 , wherein the head-mounted display is connected to the accessory through wireless signals, and receives the second image information from the accessory.
3 . The virtual image display device as claimed in claim 1 , wherein the first region of the object and the second region of the object are partially overlapped with each other but are not completely overlapped.
4 . The virtual image display device as claimed in claim 1 , wherein the head-mounted display has a first inertial measurement unit configured to measure first posture information of the head-mounted display, and the accessory has a second inertial measurement unit configured to measure second posture information of the accessory.
5 . The virtual image display device as claimed in claim 4 , wherein the head-mounted display performs a posture synchronization operation between the head-mounted display and the accessory through a wireless transmission interface based on the first posture information and the second posture information.
6 . The virtual image display device as claimed in claim 1 , wherein the head-mounted display generates a polygon picture based on the point cloud information, and combines a texture picture, the polygon picture, and the first image information to generate the stereoscopic image information.
7 . The virtual image display device as claimed in claim 1 , wherein the head-mounted display is configured to display a stereoscopic image of the object based on the stereoscopic image information.
8 . The virtual image display device as claimed in claim 1 , wherein the first image capturing device is a depth-of-field information capturing device.
9 . A stereoscopic image establishing method, comprising:
enabling a head-mounted display to perform an image capturing operation on a first region of an object to obtain first image information;
enabling a first image capturing device of an accessory to perform an image capturing operation on a second region of the object to obtain second image information, wherein the first image information is a first image, the second image information is point cloud information; establishing stereoscopic image information of the object based on the first image information and the second image information;
respectively matching a plurality of first feature points on the first image and a plurality of second feature points on the point cloud information based on an overlapping portion of the first image information and the second image information to combine the first image and the point cloud information; and
combining the first image and the point cloud information to generate the stereoscopic image information.
10 . The stereoscopic image establishing method as claimed in claim 9 , further comprising:
enabling the head-mounted display and the accessory to be connected through wireless signals, and enabling the head-mounted display to receive the second image information from the accessory.
11 . The stereoscopic image establishing method as claimed in claim 9 , wherein the first region of the object and the second region of the object are partially overlapped with each other but are not completely overlapped.
12 . The stereoscopic image establishing method as claimed in claim 9 , further comprising:
measuring first posture information of the head-mounted display;
measuring second posture information of the accessory; and
enabling the head-mounted display to perform a posture synchronization operation between the head-mounted display and the accessory through a wireless transmission interface based on the first posture information and the second posture information.
13 . The stereoscopic image establishing method as claimed in claim 9 , further comprising:
combining the first image and the point cloud information to generate a polygon picture; and
projecting a texture picture onto the polygon picture to generate the stereoscopic image information.
14 . The stereoscopic image establishing method as claimed in claim 9 , further comprising:
enabling the head-mounted display to display a stereoscopic image of the object based on the stereoscopic image information.
