<p>A hand-held or tool integrated measurement device (10) is provided for quickly and accurately performing non-contact measurements of dimensions and/or angles associated with various objects in a home or commercial work area. The measurement device (10) generally includes at least one user input element (18), a non-contact sensor (22), an image processor (24), a gravity reference device (30), and a display element (26) packaged in a portable housing assembly (12). In operation, a user initiates the measurement by activating the user input element (18) associated with the measurement device (10). The non-contact sensor (22) receives a trigger signal from the user input element (18) and is operative to collect image data representative of at least a portion of the surface of a measured object. Likewise, the gravity reference device (30) receives the trigger signal from the user input element (18) and is operative to determine a local gravity vector. The image processor (24) in turn receives the image data, from the non-contact sensor (22) and the local gravity vector from the gravity reference device (30). The image data is then converted into angular measurement data for the surface of the measured object in relation to the local gravity vector. The display element (26) is operable to visually display the angular measurement data to the user.</p> |
