3 Tips for Building Your Own Dual-Fisheye Plug-in for RICOH THETA

Avoid common pitfalls when creating your first plugin for the RICOH THETA

One-time calibration of THETA lenses for an awesome stitching experience

Changing the stitching of the RICOH THETA camera from equirectangular to dual-fisheye is an easy and fun plug-in to create.

Here are three tips to modify the Ricoh sample code and get your own custom plug-in working in minutes.

1. Set Image Size to 5792 x 2896

The default equirectangular image size is 5376 x 2688. You need to change this 5792 x 2896 or your image will get cropped and not stitch properly.

2. Enable Plug-in Permissions

When you first compile and install your plug-in into your camera with adb, it may not work and exit with a high-pitched beep-beep-beep sound and a red flashing LED. Make sure that your plug-in permissions are enabled in Vysor.

3. Download File with adb pull

Depending on where you saved the dual-fisheye image on your THETA, you may not see it with your Windows / Mac applications. Log into your camera with adb shell, then change directory into/sdcard/DCIM. Use ls to see your files. In a separate window, use adb pull /sdcard/DCIM/filename.jpg to download the file.
