Abstract:
1. A manual distance measuring apparatus comprising: a portable housing configured to be gripped by a user during use; an image acquisition means positioned within the housing and configured to record images of a measurement object and generate output characteristic variables representative of the recorded images; a laser measuring device positioned within the housing and configured to determine a distance of a measurement point on the measurement object in a measurement direction during a measuring process; and at least one computing unit positioned within the housing and configured to control, at least by open-loop control, the measurement direction depending at least on the output characteristic variables of the image acquisition means, wherein the at least one computing unit is configured to identify at least one structural element of the measurement object from the output characteristic variables of a plurality of different images and to compare the plurality of images to detect changes in orientation of the at least one structural element resulting from movement of the housing, and wherein the at least one computing unit is configured to adjust the measurement direction in response to detecting a change in orientation of the structural element resulting from movement of the housing from the comparison of the plurality of images to maintain the measurement direction directed at the measurement point.
