Spherical Video PTZ: User Guide - Quick Start Guide
Minimal Application
After Building and Installation, follow these steps:
1. Download the sample images, if you haven't already.
cd samples ./download_samples.sh cd ..
2. This example demonstrates the use of the Spherical Video PTZ engine to convert equirectangular images into rectilinear format. This command processes example_image.jpg, converting it from an equirectangular format to a rectilinear view. But you can use any other reference image as long as it is equirectangular. Run the example as:
./builddir/examples/equirectangular_to_rectilinear_npp examples/example_image.jpg
3. For this example you can use the interactive controls with the Spherical Video PTZ (Pan-Tilt-Zoom) for dynamic exploration of panoramic images. Hit the specified keys when the example is running:
