问题 I'm trying to estimate depth from a stereo system with two cameras. The simple equation that I use is: Baseline*Focal Depth = ---------------------- Disparity The field of view of the two cameras doesn't change the maximum depth allowed? It changes only the minimum depth measurable? 回答1: At the top end the measurable depth is limited by the resolution of the cameras you use, which is reflected in the disparity. As depth becomes greater disparity tends to zero. With a greater field of view it

It changes only the minimum depth measurable? At the top end the measurable depth is limited by the resolution of the cameras you use, which is reflected in the disparity. As depth becomes greater disparity tends to zero. With a greater field of view it will effectively be zero at a lower depth. Thus a greater field of view lowers the maximum depth measurable,

NV_STEREO_IMAGE_SIGNATURE and DirectX 10/11 (nVidia 3D Vision)

I'm trying to use SlimDX and DirectX10 or 11 to control the stereoization process on the nVidia 3D Vision Kit. Thanks to this question I've been able to make it work in DirectX 9. However, due to some missing methods I've been unable to make it work under DirectX 10 or 11. The algorithm goes like this: Render left eye image Render right eye image Create a texture able to contain them both PLUS an extra row (so the texture size would be 2 * width, height + 1) Write this NV_STEREO_IMAGE_SIGNATURE value Render this texture on the screen My test code skips the first two steps, as I already have a

Unity- Photosphere Photo Viewer for Google Cardboard

I am trying to build a Photosphere-like application with Unity3D and use it along with Google cardboard. I need to load different panoramic view photos and be able to view them stereoscopically, by using the Cardboard goggles. I am having problem to use the pano images and render it into stereoscopic view in Unity. Any suggestions will be gratefully received. felixwcf Simplest solution that I can give to you: A. Install your Unity Pro with Android Pro plugins, setup Cardboard SDK For Unity , install Android Build tools and SDK. B Setup Skybox Get a stereoscopic panorama image (Might take a

3d reconstruction from 2 images without info about the camera

I'm new in this field and I'm trying to model a simple scene in 3d out of 2d images and I dont have any info about cameras. I know that there are 3 options : I have two images and I know the model of my camera (intrisics) that I loaded from a XML for instance loadXMLFromFile() => stereoRectify() => reprojectImageTo3D() I don't have them but I can calibrate my camera => stereoCalibrate() => stereoRectify() => reprojectImageTo3D() I can't calibrate the camera (it is my case, because I don't have the camera that has taken the 2 images, then I need to find pair keypoints on both images with SURF,
