The coordinateĪxis has z pointing up, y pointing forward and x to the right, a right handed Rotations in the order roll (-y), followed by a pan (-x), and lastly tilting (-x). Sphere2sphere -x 20 -z 30 -y 40 imagename.jpg Performed in reverse (output to input) the rotations are applied in reverse order. When specifying the rotation on the command line, because the image mapping is This will becomeĬlear later in the example using a Ricoh 360 camera. Results than if the rotations were performed in a different sequence. Performed, transforming in the order of roll-tilt-pan will not in general give the same f s output file name, default: derived from input file nameĬritical in any such process is the order in which the rotation operations are eiv create the Eckert IV projection, default = off wag create the Wagner projection, default = off ait create the Aitoff projection, default = off wer create the Werner projection, default = off bon create the Bonne projection, default = off sin create the Sinusoidal projection, default = off bot create the Bottomley projection, default = off tob create the Tobler projection, default = off mol create the Mollweide projection, default = off ham create the Hammer projection, default = off eqi create the Equirectangular projection, default = on l2 pa1 pa2 pb1 pb2 straighten to specified pair of lines, default: disabled cp x y center on specified pixel, default: disabled h n output image height, default = half image width w n output image width, default = input image width Output image and supersampling level, it does not depend on the size of the input As such the performance is related to the size of the (and subpixels) in the output image and finding the best estimate of the new pixel It functions internally by considering each pixel It employsĪ straightforward super-sampling antialiasing to avoid the usual effects that canĪrise from discrete sampling. The usage string for the utility, called sphere2sphere, is given below. The case of the Ricoh 360 camera that conveniently stores the camera orientation Of one click hand held 360x180 degree cameras. Would pay particular attention to levelling the tripod, today there are any number Photographers capturing images that will be stitched/blended into an equirectangular #MAKE TINY PLANET FROM JPEG EQUIRECTANGULAR MANUAL#There are manual methods for both the above, but more difficult is levelling anĮquirectangular image captured with the camera not perfectly level. Panning the camera, also known as changing the camera heading. Image to be located in a particular location. Presenting the equirectangular as a flat image that one wants subject matter in the While equirectangular images have no natural "forward", there are occasions when The image or when the equirectangular is reprocessed to create other outputs (for While these may not be noticed when viewing theĮquirectangular image flat, they can be obvious when interactively navigating within #MAKE TINY PLANET FROM JPEG EQUIRECTANGULAR SOFTWARE#Scaling in image editing software that does not know about the wrap-around can result in hair-lineĭefects on the left and right edge. One needs to be careful that the wrap-around seam is handled correctly. Such as cylindrical panoramas or equirectangular projections (spherical panoramas), When scaling images that wrap around horizontally (the 0 to 360 degree transition), Why you might ask would one want to do that? There are at The following describes a utility to convert an equirectangular image into anotherĮquirectangular image. #MAKE TINY PLANET FROM JPEG EQUIRECTANGULAR CODE#It includes a demo application and an invitation toĬonvert an image of your choice to verify the code does what you seek.įor more information please contact the author.
