Mobile handheld instruments and methods

Abstract

A mobile handheld instrument having a camera, display, user interface, spatial sensors and inertial measurement unit. Upon user selection of an image region within a captured image a processor may determine an orientation of a surface within the image and the region is forced into alignment with the determined orientation of the surface. The processor may also overlay a plurality of markers on a displayed camera feed, each marker being overlaid at a target position for which spatial sensors have already captured data. A user may also select target categories and captured data sets obtained by spatial sensors and associated with the selected target categories. Measurements captured for target points may be overlaid on the displayed camera feed. The determined measurement data may be updated based on a user instruction to alter the set of target points. Spatial data sets may be corrected for detected movement of the instrument and to stitch the captured images to form an image file having a larger coverage than the camera field of view. The spatial data sets may be corrected for the detected movement of the instrument and to determine one or more of a distance between two target points or relative positions of two target points. A back-facing camera directed towards a user may be used to detect movement of the instrument.
