Abstract
An accelerometer captures multiple frames of image information and uses the image information to generate acceleration data related to an object. In particular, multiple image frames are used to determine relative movement between a target and an image collection system. The relative movement between the target and the image collection system is tracked over time to generate acceleration data related to the object.
Claims26
An accelerometer comprising:
- a target;
- an image collection system configured to capture image information related to the target;
- a tracking engine configured to process the image information to track movement of the target relative to the image collection system and to output movement information;
- and
- conversion logic configured to generate acceleration data related to an object in response to the movement information.
2 more elements
A method for obtaining acceleration data related to an object, the method comprising:
- capturing image information from a target using an image collection system;
- processing the image information to track movement of the target relative to the image collection system, wherein the movement is indicated by movement information;
- and
- converting the movement information to acceleration data related to the object.
1 more element
An accelerometer comprising:
- a target;
- an image collection system configured to capture image information related to the target;
- wherein one of the target element and the image collection system is connected to an object by a rigid connection and wherein the other one of the target element and image collection system is connected to the object by an inertial connection and wherein the target includes a feature, which when moved relative to the image collection system, produces image information that is distinguishable in at least one direction;
- a tracking engine configured to process the image information to track movement of the target relative to the image collection system and to output movement information;
- and
- conversion logic configured to generate acceleration data related to an object in response to the movement information.
