摘要
An apparatus and method for measuring the location of points in a defined reference frame. The apparatus includes a plurality of linear and angular accelerometers that facilitate kinematic navigation as the device moves about in space. Thus, measurements may be taken from any orientation and location. In a first embodiment of the apparatus, a distance measuring device measures the distance to the point along a measuring axis and then calculates the location of the point in the defined reference frame based upon the distance to the point and the location and orientation of the device. In a second embodiment of the apparatus, a user touches the measured point with a touching member that aligns with the measuring axis. A computing device then calculates the location of the point based upon the location of the touching member and the location and orientation of the device. Data transfer port facilitates the transfer of data acquired by the device to other systems for immediate further use or display. Also included with the invention are features for aligning the axes of the defined reference frame with the earth's local gravitational and north directions. The establishment of these references along with further associated steps facilitates the correction of positional errors.
