I use GPUImage to get texture from movie and use above custom shader to convert that to equirectangular format. First, I oriented my research to imagemagick. I would use. Convert dual fisheye image to equirectangular images for mp4 video files. In order to do above, what sort of transformation operations are required to be performed on input video (equirectangular format), so that I can get the cropped normal field of I recently found a couple of GitHub tools that convert cubemap faces into equirectangular panoramas and vice versa: Panorama to Cubemap by jaxry; Cubemap to Panorama by danilw ; I've been using the Panorama to Cubemap tool to port SpaceEngine skyboxes into CS:GO. Is there a way to do this calculation on the GPU, preferably using Python? I have read that it should be possible using OpenGL or I used a mp4 dual-fisheye movie as input. Tested: Raspberry Pi 3/4. 1 specification (plus some hacks to make it work). I've used some SO posts in order to create equirectangular image from a cubeMap and vice versa. Here's what you can assume: The center of the image is always facing south; the image is always level looking straight at the equator. to do it. Here's what I know: The image size is 5760x2880 which means the equator is at 1440px vertically. To deal with white-outs, etc. com, wikipedia How can I orient the virtual camera in that sphere with code (python preferred) given input as equirectangular video format, so that I can get the image of that particular angle in that sphere. . 10 from the OpenGL 4. PNG files) of the transformation process to visualize the distortion that is occurring during the transformation. On the other hand, equirectangular images are 360-degree panoramic images that can be easily displayed on the web, as they are a rectangular projection of a spherical convert your image+2D coordinates to 3D normalized vector. jpg format. Open up either terminal, or command prompt and then run the following command replacing the file path with a path to the folder containing the six cube map images on your computer:. 6 ( c++ is WIP). This Medium article, while in Python might offer some further reading on the topic. norm(orientation) if cp. A cubemap will be generated from your image. In order to calculate the best estimate of the color at each pixel in the equirectangular image given a cubemap with 6 faces: Firstly, calculate polar coordinates that correspond to each pixel in the spherical image. The left fisheye above mapped into equirectangular space is shown below, it fills more than half the equirectangular image because the lens is 210 degrees. I have found py360convert, which allows convert from equirectangular to cubemap, from which it should be easier to obtain an azimuthal projection. plot3d once you have your planet, so I'm going to concentrate on texture mapping a planet to a sphere using mayavi. wolfram.

If I use a Python script and do the calculations on the CPU, it takes several seconds to perform the conversion. There is a new filter in I think the problem comes from the edge variable. Once installed, copy the createEquiFromSquareFiles. It seems to indicate that once you have obtained the K and D values from fisheye::calibrate you can then use fisheye::initUndistortRectifyMap (note that D can be empty, as it seems to be in your case) to generate two Maps, which can then be used with remap to transform the warped input Description: This Python code demonstrates how to convert a normal image to equirectangular format using the Pillow library. Then I can use google photos and the photosphere javascript from photo-sphere-viewer. References: mathworld. mlab. So if you press the Screenshot button with that view you can save a equirectangular image/screenshot. Method: Our approach still consists of two steps. Here, we assume that there is an overlap in the edge regions of the two images, and we need to find the alignment transformation that allows them to perfectly overlap in this overlap area. ffmpeg -y -i in. I did it with Pano2VR. w: Output equirectangular width. Question is how to prepare the cubeMap from flat panorama at first place ? I want to create a C++ code with the OpenCV4 library that convert a fisheye image to an equirectangular image. 8. The option --invert does equirectangular to mercator.

It’s all about defining the correct transformation maps for OpenCV. I want to know the mathematical equations with which such or similar transformation can be achieved. How do I convert longitude and latitude into X and Y on the canvas so I can change the DIVS left and top style attributes so the label renders in 3D space and appears fixed to its coordinates? UPDATE: For clarity, how does one take planet earth longitude and latitude, and convert it into X Y pixels inside a mesh? my assumption is that the natural wrapping of an image around a sphere acts as a sort of mercator-to-equirectangular conversion (because an unwrapped sphere texture is 2x wide while being 1x tall and when wrapped the image appears scrunched together at the poles) – I am trying to transform an equirectangular projection to an azimuthal projection with python. Check it out on on GitHub! Using the moderngl python library, the converter runs the input image through a remapping shader. 🌐 Plugin for rendering 6DOF equirectangular 360 images and videos Command line Python script that 1) takes logo file, 2) converts to equirectangular image, 3) transforms to desired size, and 4) overlays on-top of an equirectangular photo as a nadir.

Uploading your files is easy. For those not familiar with OpenCV, think of Mat as an image. Does anyone know how to convert a normal picture into a portrait mode picture? I want to take a background image that I created in photoshop and convert it to equirectangular so that when I bring it into Premiere, it will function as a 360 background. org to view them in a way compatible with all my other photospheres. You only need a function that turns (x,y) from your fisheye image into (latitude, longitude), and then a function that turns this latitude, longitude into a pixel on your equirectangular output image (which is how geo_w_px was calculated It should therefore be possible to merge the two fisheye images together to form a complete equirectangular projection, which defines the whole visible world. I have a few objects of known size on a surface. This a command line utility and as such straightforward to script to convert sequences of frames that make up a movie. mp4 -vf v360=dfisheye:e:yaw=-90 -c:v libx265 -b:v 40000k -bufsize 5000k -preset ultrafast -c: Unable to convert dual fisheye image to I am trying to visualize the map distortion that occurs when reprojecting from Mercator to equirectangular coordinate systems.
