Abstract
Described are systems and methods for measuring objects using stereoscopic imaging. After determining keypoints within a set of stereoscopic images, a user may select a desired object within an imaged scene to be measured. Using depth map information and information about the boundary of the selected object, the desired measurement may be calculated and displayed to the user on a display device. Tracking of the object in three dimensions and continuous updating of the measurement of a selected object may also be performed as the object or the imaging device is moved.
Claims20
A system for measuring a dimension of an object, comprising:
- a pair of stereoscopic image sensors;
- and
- a control module configured to:
- capture a stereoscopic image of the object;
- determine one or more keypoints of the object;
- determine a boundary of the object from the one or more keypoints;
- and
- calculate a dimension of the object based on a length of the determined boundary of the object;
- and
- a display configured to display the object and the calculated dimension.
A method for measuring a dimension of an object, comprising:
- capturing a stereoscopic image of the object;
- determining one or more keypoints of the object;
- determining a boundary of the object from the one or more keypoints;
- and
- calculating a dimension of the object based on a length of the determined boundary of the object.
An imaging apparatus, comprising:
- a pair of stereoscopic image sensors;
- a sensor control module configured to capture a stereoscopic image of an object;
- a keypoint module configured to determine one or more keypoints of the object;
- a boundary calculation module configured to determine a boundary of the object from the one or more keypoints;
- a user interface module configured to accept a user-selected boundary of the object;
- a dimension calculation module configured to calculate a dimension of the object based on a length of the determined boundary of the object;
- and
- a display configured to display the object and the calculated dimension.
A stereoscopic imaging device, comprising:
- a pair of stereoscopic image sensors;
- means for determining one or more keypoints of an object;
- means for determining a boundary of the object from the one or more keypoints;
- means for calculating a dimension of the object based on a length of the determined boundary of the object;
- and
- a display configured to display the object and the calculated dimension.
A non-transitory computer readable medium, storing instructions that when executed by a processor, cause the processor to perform the method of:
- capturing a stereoscopic image of an object;
- determining one or more keypoints of the object;
- determining a boundary of the object from the one or more keypoints;
- calculating a dimension of the object based on a length of the determined boundary of the object;
- and
- tracking the one or more keypoints of the object in three dimensions.
