I made a little script to make a 360 spherical panorama photo, using a remote controlled IP cam,
Looking at the API CGI, i only needed to control the movement of the camera and getting a snapshot.
- Point camera down
- Point camera maximal left
- Take picture
- Point a little to the right
- Take picture, loop until max right
- Point a little more up and go max left
- Doing same loop as above, until pointing maximal up
After getting all those pictures, i only needed to stitch them using Hugin.
When viewing the image with VR Glasses, i could look around my room, without image distortion, like below flattend example.
The ipcam generates a token, which you have to use in your curl commands.
