thetaexif is a Python library for RICOH THETA image. It provides a EXIF reader class and a rectification tool.

Requirements

• Python 3.6 or later
• Pillow
• Scipy

Setup

::

$ pip install thetaexif

Usage

In Python

::

>>> from thetaexif import ExifReader, tag
>>> reader = ExifReader('image.jpg')
>>> reader.makernote[tag.FIRMWARE_VERSION]
b'Rev0102'
>>> reader.theta[tag.ZENITH_ES]
(Fraction(20, 1), Fraction(-24, 1))

Rectification

rectify command reads gyroscope and compass data and rotate images to rectify camera pose.

Rectify image.jpg and save to image_rectified.jpg::

$ theta-tool rectify image.jpg

Rectify image.jpg using compass data (rotate image to face the north)::

$ theta-tool rectify -c image.jpg

Keep EXIF and rectify::

$ theta-tool rectify -e image.jpg
