Using accelerometer information for determining orientation of pictures and video images

摘要

A computing device, such as a mobile device, can capture pictures or video images using a digital camera and obtain associated orientation information using an accelerometer. The orientation information can be used to adjust one or more of the captured pictures or video images to compensate for rotation in one or more planes of rotation. The orientation information can be saved along with the captured pictures or video images. The orientation information can also be transmitted or streamed along with the captured pictures or video images. Image matching operations can be performed using pictures or video images that have been adjusted using orientation information.

主权项

1. A method, implemented at least in part by a computing device, for capturing and processing video data, the method comprising:
for each of a plurality of video images:
obtaining, by the computing device, orientation information of the computing device at a time of capturing the video image, wherein the computing device comprises a three-axis accelerometer, and wherein the orientation information is obtained from the three-axis accelerometer;adjusting, by the computing device, the captured video image based on the orientation information, wherein the adjusting the captured video image based on the orientation information comprises:
obtaining a reference orientation that is an orientation of an initial video image of the video data; andadjusting the video image in real-time to return the video image to the reference orientation; andoutputting, by the computing device, for display the adjusted captured video image;wherein the obtaining, adjusting, and outputting are performed in real-time during recording of the plurality of video images by the computing device.
