High dynamic range image registration using motion sensor data

摘要

Motion sensor data may be used to register a sequence of standard dynamic range images for producing a high dynamic range (HDR) image, reducing use of computational resources over software visual feature mapping techniques. A rotational motion sensor may produce information about orientation changes in the imaging device between images in the sequence of images sufficient to allow registration of the images, instead of using registration based on analysis of visual features of the images. If the imaging device has been moved laterally, then the motion sensor data may not be useful and visual feature mapping techniques may be employed to produce the HDR image.

主权项

1. A non-transitory program storage device, readable by a programmable imaging device, comprising instructions stored thereon to cause the programmable imaging device to:
capture a sequence of images with a programmable imaging device; obtain rotational orientation data associated with images of the sequence of images from an orientation sensor of the programmable imaging device; determine whether translational motion of the programmable imaging device occurred during capture of the sequence of images; calculate registration parameters for the sequence of images responsive to the rotational orientation data when translational motion of the programmable imaging device was determined not to have occured during capture of the sequence of images; and calculate the registration parameters for the sequence of images ignoring the rotational orientation data when translational motion of the programmable imaging device was determined to have occured during capture of the sequence of images.
