全立体全景由一对全景图像组成，其中一个全景用于左眼，另一个全景用于右眼。一对全立体声可提供高达 360 度的立体感觉。 OmniStereo 全景图可以通过拼接旋转摄像机或专门设计的摄像机的图像来创建。立体感是左右图像之间的差异的函数。这种视差是相机之间的距离（基线）与到物体的距离之比的函数：基线越长且物体越近，视差越大。由于我们的眼睛相距固定距离，因此我们对远处物体失去了立体感。可以控制通过旋转摄像机的马赛克图像生成的全立体全景图中的视差。对于较远的场景，基线可以变大，对于较近的场景，基线可以变小。描述了一种用于构造全立体全景图的方法，该全立体全景图对于远处的场景具有较大的基线，对于较近的场景具有较小的基线。基线可以在全景图中从具有较近对象的方向改变为具有较远对象的方向。
An omnistereo panorama consists of a pair of panoramic images, where one panorama is for the left eye, and another panorama is for the right eye. An omnistereo pair provides a stereo sensation up to a full 360 degrees. OmniStereo panoramas can be created by mosaicing images from a rotating video camera, or by specially designed cameras. The stereo sensation is a function of the disparity between the left and right images. This disparity is a function of the ratio of the distance between the cameras (the baseline) and the distance to the object: disparity is larger with longer baseline and close objects. Since our eyes are a fixed distance apart, we loose stereo sensation for far away objects. It is possible to control the disparity in omnistereo panoramas which are generated by mosaicing images from a rotating camera. The baseline can be made larger for far away scenes, and smaller for nearer scenes. A method is described for the construction of omnistereo panoramas having larger baselines for far away scenes, and smaller baseline for closer scenes. The baseline can change within the panorama from directions with closer objects to directions with further objects.
