Convert a equirectangular panorama image into a normal perspective view.

Equirectangular2Perspective

This repository is a set of codes to convert a equirectangular panorama image into a normal perspective view.

Requirement

• OpenCV 3.4

How to use

1. Put a input equirectangler image on the data directory

2. Enter the following commands:

   $ mkdir build && cd build
   $ cmake ..
   $ make
   $ ./Equirectangular2Perspective
   

3. Parameters:

   // Output image dimension
   const int height = 720;
   const int width = 1080;
   
   // z-axis angle (0: forward, 180: backword)
   float theta = 180.0f;
   
   // y-axis angle (>0: upper, <0: lower)
   float phi = 0.0f;
   
   // FOV of the output perspective image
   float FOV = 120.0f;
   
   Equirec2Perspec equiParser;
   equiParser.setParams(inputImage, FOV, height, width);
   
   equiParser.equirectangular2perspective(inputImage, outputImage, theta, phi);

Result

Input: panorama image

Output: perspective image
