Abstract
Example methods and systems for camera calibration using structure from motion techniques are described herein. Within examples, an autonomous vehicle may receive images from a vehicle camera system and may determine an image-based pose based on the images. To determine an image-bases pose, an autonomous vehicle may perform various processes related to structure from motion, such as image matching and bundle adjustment. In addition, the vehicle may determine a sensor-based pose indicative of a position and orientation of the vehicle through using information provided by vehicle sensors. The vehicle may align the image-based pose with the sensor-based pose to determine any adjustments to the position or orientation that may calibrate the cameras. In an example, a computing device of the vehicle may align the different poses using transforms, rotations, and/or scaling.
