Image processing device, image processing method, and image processing system
View Patent ↗An image acquisition unit acquires an image captured by a first imaging device provided in a HMD for presenting an image observed when a three-dimensional image in a virtual three-dimensional space is projected onto a real-world setting, the first imaging device being configured to visualize an area including a field of view of a user wearing the HMD. A marker detection unit detects a marker included in the image captured by the first imaging device and acquired by the image acquisition unit. The image acquisition unit acquires an image captured by a second imaging device having an angle of view that at least partially overlaps an angle of view of the first imaging device. If the marker is not captured in the image captured by the first imaging device, the marker detection unit detects the marker in an image captured by the second imaging device.
1. An image processing device comprising:
circuitry configured to:
acquire an image captured by a first imaging device provided in an optical head-mounted display (HMD) for presenting an augmented real-world image,
wherein a three-dimensional image in a virtual three-dimensional space is projected onto a real-world setting in the augmented real-world image,
wherein the image captured by the first imaging device includes an area including a field of view of a user wearing the HMD;
acquire an image captured by a second imaging device configured at a predetermined stationary angle of view in a general direction towards the user and the HMD;
detect a feature of the image captured by the first imaging device; and
detect a feature of the image captured by the second imaging device when the feature of the image captured by the first imaging device is not detected,
wherein the predetermined stationary angle of view at least partially overlaps an angle of view of the first imaging device.
2. The image processing device of claim 1 , wherein the circuitry is configured to generate an augmented real-world image based on the detected feature.
3. A method for presenting an augmented real-world image comprising:
acquiring an image captured by a first imaging device provided in an optical head-mounted display (HMD) for presenting the augmented real-world image,
wherein a three-dimensional image in a virtual three-dimensional space is projected onto a real-world setting in the augmented real-world image,
wherein the image captured by the first imaging device includes an area including a field of view of a user wearing the HMD;
acquiring an image captured by a second imaging device configured at a predetermined stationary angle of view in a general direction towards (or “for capturing an image including”) the user and the HMD;
detecting a feature of the image captured by the first imaging device; and
detecting a feature of the image captured by the second imaging device when the feature of the image captured by the first imaging device is not detected,
wherein the predetermined stationary angle of view at least partially overlaps an angle of view of the first imaging device.
4. The method of claim 3 , further comprising:
generating an augmented real-world image based on the detected feature.
5. The method of claim 3 , wherein the augmented real-world image is not generated when the feature of the image captured by the first imaging device and the feature of the image captured by the second imaging device are not detected.
