Converting Cylindrical Pano X And Y Pixel Position To Polygon Hotspot I want to know how to calculate the pixel position of my image to ath, atv of a polygon hotspot.for example, i know that if x = 125,000, and y = 25,000 then i should get ath = 0 and atv = 0. Pano2vr is an application to convert spherical or cylindrical panoramic images into html5 vr tours with features such as customizable skins, tour building, multiresolution, hotspots and directional sound.
Converting Cylindrical Pano X And Y Pixel Position To Polygon Hotspot We tested 3 methods for image mosaicing: using a simple overlap, a linear blend, and a sigmoid blend. output images are shown for all 3 methods, but the sigmoid blend gave the best results. I'm following the calculations exposed at krpano forum wbb inde…&threadid=11338, generally calculations are correct, but on some cases looks like there's an offset in calculations, like krpano renders an area of the image, so coordinates of the images get shfited vertically. I'm having an issue related to converting my hotspots' cylindrical coordinates to width height coordinates. context: i have thousands of hotspots defined throughout hundreds of my cylindrical panoramas. now i need to get their width height pixel location equivalents on the original images. I want to define a polygonal hotspot and embed an image into it (image overlay). taking an example from the krpano download, in the demotour weingut virtual tour, there are a couple paintings on the wall which are polygonal hotspots, when clicked, a 2d image will popup.

To figure out the right offsets to move the image, simply figure out the centroid of the polygon, translate the polygon so that centroid is at the origin, and then retranslate it so that it's at the centre of the image. Just sharing a code snippet to warp images to cylindrical coordinates, in case you’re stitching panoramas in python opencv… this is an improved version from what i had in class some time ago…. Double click in the viewer to draw the hotspot. this adds the first anchor point. now move the mouse and then click to add the next anchor, and finally double click to add a last point or right click to finish the shape. once you do this the properties panel will open. It can be envisioned by imagining wrapping a flat piece of paper around the circumference of a sphere, such that it is tangent to the sphere at its equator. shining a light from the center of the sphere then projects the spherical surface onto the flat paper.
