Systems and methods for angular offset calibration for composite image generation

A method comprising:

• causing, by one or more processors, an image capture device to rotate about an axis of rotation of the image capture device to capture, for a plurality of range of angles, a plurality of first constituent images, each first constituent image of the plurality of first constituent images corresponding to a respective range of angles about the axis;
• determining, by the one or more processors, during a calibration process, for each respective range of angles of the plurality of range of angles, a respective offset caused by a difference between the axis of rotation and a reference axis using the respective first constituent image;
• during a composite image generation process subsequent to the calibration process,
• identifying, by the one or more processors, a plurality of second constituent images captured by the image capture device rotated about the axis of rotation of the image capture device, each second constituent image of the plurality of second constituent images corresponding to a respective range of angles about the axis;
• aligning, by the one or more processors, using the respective offset for each identify a plurality of second constituent images captured by the image capture device rotated about the axis of rotation of the image capture device, each second constituent image of the plurality of second constituent images corresponding to a respective range of angles about the axis;
• and
• storing, by the one or more processors, in one or more data structures, the composite image.

A non-transitory computer readable medium storing instructions, which when executed by one or more processors, cause the one or more processors to:

• cause an image capture device to rotate about an axis of rotation of the image capture device to capture, for a plurality of range of angles, a plurality of first constituent images, each first constituent image of the plurality of first constituent images corresponding to a respective range of angles about the axis;
• determine, during a calibration process, for each respective range of angles of the plurality of range of angles, a respective offset caused by a difference between the axis of rotation and a reference axis using the respective first constituent image;
• during a composite image generation process subsequent to the calibration process,
• identify a plurality of second constituent images captured by the image capture device rotated about the axis of rotation of the image capture device, each second constituent image of the plurality of second constituent images corresponding to a respective range of angles about the axis;
• align, using the respective offset for each respective range of angles of the plurality of range of angles determined using the plurality of first constituent images, the plurality of second constituent images to generate a composite image;
• and
• store, in one or more data structures, the composite image.
