** Equirectangular Projection**. An equirectangular projection is a cylindrical equidistant projection, also called a rectangular projection, plane chart, plate carre, or unprojected map, in which the horizontal coordinate is the longitude and the vertical coordinate is the latitude, so the standard parallel is taken as The equirectangular projection was used in map creation since it was invented around 100 A.D. by Marinus of Tyre. See Mathworld's page for more detailed information on the mathematics of this projection. In an equirectangular panoramic image all verticals remain vertical, and the horizon becomes a straight line across the middle of the image. Coordinates in the image relate linearly to pan and tilt angles in the real world.

Spherical/Equirectangular Projection. This projection is used to project the whole sphere on a flat surface. The result of that is an equirectangular image, with a 2:1 ratio. The width is exactly twice the height. This is logical, since it covers 360 degrees horizontally and 180° vertically. You will see that in this projection, the top and bottom of the image appear very distorted and this. This simple cylindrical projection converts the globe into a Cartesian grid. Each rectangular grid cell has the same size, shape, and area. All the graticular intersections are 90 degrees. The central parallel may be any line, but the traditional Plate Carrée projection uses the equator. When the equator is used, the grid cells are perfect squares, but if any other parallel is used, the grids.

This group is for equirectangular projected photos that have the full 360° x 180° view (2:1 ratio). Also, photos that have covers for the zenith or nadir and meet the same 2:1 size ratio as full 180° x 360° panos will be accepted if they give the same appearance as the full spherical projection The resulting equirectangular projection is as follows. A blend region of 10 degrees is used, for this example the command line might be dualfish2sphere -w 3000 -b 10 -a 2 outdoor.txt Note the poor alignment in the red ellipse regions. 2.

The first is an equirectangular projection in 2D, sometimes called a lat-long. This is the format for uploading to youtube. It's a little weird looking and it can take up a second to wrap your head around, but imagine taking a globe and stretching it out flat into a map. Now it starts to make a lot more sense. CUBEMAPs is another way to visualize spherical videos. A cubemap is a collection of six squires that represent a 360 environment. You can visualize it as six squares forming the faces. Equirectangular projection Equirectangular Projection h360° v180° Also called the non-projection, this is a representation of the sphere which maps longitude directly to the horizontal coordinate, and latitude to the vertical coordinate. This projection is often used for the source images in panoramic viewers like PTViewer Spherical/Equirectangular Projection This projection is used to project the whole sphere on a flat surface. The result of that is an equirectangular image, with a 2:1 ratio. The width is exactly twice the height Direct Polar, known as Spherical or Equirectangular Projection. While not strictly a projection, a common way of representing spherical surfaces in a rectangular form is to simply use the polar angles directly as the horizontal and vertical coordinates. Since longitude varies over 2 pi and latitude only over pi, such polar maps are normally presented in a 2:1 ratio of width to height. The most noticeable distortion in these maps is the horizontal stretching that occurs as one approaches the. Equirectangular image presents a sphere, it's distorted so that meridians and parallels on the sphere are shown as straight vertical and horizontal lines. An example from Wikipedia: In the left there's a spherical map and in the right there's the equivalent plane map, the equirectangular projection from sphere to a rectangle

My base data set is a world map 8192x4096 pixels big using a equirectangular projection. I picked this as I can find lots of data with this projection that I can line up, the latitude and longitude lines are square, and the projection looks pleasing to me.

- Ever want to convert from a cubemap (6 textures of a cube) to a spherical/equirectangular map? I randomly decided to fiddle around with generating simple planet textures and thought it might come in handy since planets are often just sphere meshes with a spherical texture mapped on em. Sure, they compress at the top and bottom, but they're easy to apply and look decent most of the time.
- The equirectangular projection is one of the many types of transformations that can be used to map the coordinates from a curved surface, such as that of the celestial sphere, onto a flat surface, for example, that of a sheet of paper. Due to the different characteristics of flat and curved surfaces, some properties of the original coordinate system - distances, areas, angles, and others.

So as 360 cameras and live streams become more popular I have more clients wanting to add in PIPS and Titles in their streams. Right now to do so I have to create the content and apply the. In particular, equirectangular projection incorporates a complete field-of-view but introduces distortion, whereas cubemap projection avoids distortion but introduces discontinuity at the boundary of the cube. Thus we propose a bi-projection fusion scheme along with learnable masks to balance the feature map from the two projections. Moreover, for the cubemap projection, we propose a spherical.

There are no poles as in equirectangular projection, which contains redundant information. Cube maps are easier to project. Each face is mapped only on the corresponding face of the cube. Cube maps have been used in computer graphics for a long time, mostly to create skyboxes and reflections, and we wanted to bring the same capability to anyone who wants to stream high-quality video. Today, we. IMPORTANT! Original image must be equirectangular projection. Click here for more info

- Using (lon, lat) as (x,y) Cartesian coordinates to make the map is tantamount to the Equirectangular projection and so is suitable for texture-mapping onto the sphere or for applying an Orthographic projection. Note that Tissot indicatrices are not suitable as a solution: they only represent local distortions of infinitesimal circles

- The equirectangular projection was used in map creation since it was invented around 100 A.D. by Marinus of Tyre. See Mathworld's page for more detailed information on the mathematics of this projection. In an equirectangular panoramic image all verticals remain vertical, and the horizon becomes a straight line across the middle of the image. Coordinates in the image relate linearly to pan and.
- Equirectangular projection simply unwraps the sphere, mapping the longitude to the X coordinate, and the latitude to the Y. Here is a familiar example, the globe laid flat: Notice that the image widens and it progresses toward the poles. The reasoning is that the spatial distance between longitude positions decreases the closer you get to the pole. The smaller circumference of a line of.
