Some embodiments of the invention relate to a surveying apparatus in the form of a scanner comprising a beam deflection unit, such a beam deflection unit and a measuring method to be carried out with said surveying apparatus. The surveying apparatus comprises a radiation source for generating measurement radiation and a detector for receiving reflected measurement radiation, called reflection radiation for short, which was reflected at an object of interest, wherein measurement radiation and reflection radiation have substantially the same optical path. Situated in said optical path there is a beam deflection unit mounted rotatably about a rotation axis and serving for adjustably aligning the measurement radiation and for capturing the reflected radiation.

A system including a pointing rod 4 positioned on a measurement point X, a prism 3 fixed at a position deviated by a first fixed length L1 from the measurement point X in an axial direction PP of the pointing rod 4, an inclination casing 5 for fixing an analysis pattern 41 located at a position deviated by a second fixed length L2 from the prism 3 in an axial direction of the pointing rod 4 and is perpendicular to a surface with respect to the axial direction of the pointing rod 4, and a survey machine 2 having an image-taking section 22, a section of measuring a distance to the prism, and a section of measuring an angle 11,12. The position of the measurement point is measured from a position of the prism 3, an inclination direction A of the pointing rod 4, and the first fixed length L1.

The inclination sensor includes a gimbal mechanism rotatably supported around a first shaft and a second shaft, a first motor, a second motor, an acceleration sensor disposed in the gimbal mechanism with an origin point of coordinate axes being coincident with a point of intersection of a shaft center of the first shaft and a shaft center of the second shaft, and a control unit that simultaneously rotates the first shaft and the second shaft to continuously rotate the acceleration sensor around the first shaft and the second shaft and applies frequency analysis to the output values from the acceleration sensor to arithmetically determine the inclination angle with respect to the horizontal direction.

Systems and methods for determining elevation based on structural modeling and light detection and ranging (LIDAR) data are disclosure. LIDAR bare earth data corresponding to an area within a parcel boundary is obtained as preliminary elevation data. A basis of structure boundary is determined for a structure within the parcel boundary based on an absence of the LIDAR bare earth data within a region in the area. Three-dimensional models are generated based on photographic data, to represent portions of the structure that affect LIDAR signals. A structure boundary for the structure is determined based on the basis of structure boundary in combination with supplemental elevation data generated using the three-dimensional models. Adjacent grade values are determined based on a portion of the preliminary elevation data and supplemental elevation data corresponding to an area between the structure boundary and a buffer boundary.

The present invention is bubble level and laser level multi-tool. The projection arm with a laser pointer is mounted on a sliding track system of the body section and can be pointed at various angles using a angle degree dial. The projection arm can be folded inside the track system of the body section for storage and transportation.

A measurement and installation data indicating apparatus including a distance image sensor that obtains distance image data in a predetermined range, a projector that projects an image on a projection plane in a predetermined range, an inclination data obtaining part that obtains inclination data on a detection optical axis and a projection optical axis relative to a vertical direction, a positional data obtaining part that obtains coordinate data on a present position and a target position, and a terminal controller that generates, based on the coordinate data, a target information image related to the target position and seen from the present position. The terminal controller corrects the target information image to fit to a shape of the projection plane based on the distance image data and the inclination data, and projects the corrected target information image by the projector.

A laser level containing a housing, an electronic tilt sensor located in the housing; a controller to which the electronic tilt sensor is connected, and a laser module. The controller is communicable with a first display device and a second display device. The laser line is adapted to project a straight ground laser line on a flat surface. The electronic tilt sensor is adapted to detect a tilt of the laser level and provide a measurement signal to the controller. The controller is adapted to provide a display signal to the first and second display devices to display information about the tilt. By using an electronic tilt sensor, the laser level can provide accurate indicate of the tilt of the device and also allows such tilt information to be processed further.

A Robotic Total Station (RTS) system includes an RTS disposed for at least two-axis rotation on a tripod, and a rover including a pole mounted prism and GNSS receiver with inclination sensors. The RTS rotates on the tripod to point towards the rover and generate an RTS-position measurement using an optical signal reflected by the prism. The RTS is communicably coupled to the data collector and/or the GNSS receiver, and receives and uses the GNSS-derived position measurements and the inclination data for the range pole in real-time, to automatically track and point the RTS towards the prism.

A protection apparatus for an appliance supported by a tripod, the protection apparatus including: a tilt sensor, for alerting upon tilting of the tripod; and an airbag inflated upon the alerting for protecting the appliance. The airbag is shaped to comprise at least one of three protrusions, projected outward upon airbag inflation, each protrusion being directed in one of the common tilting directions perpendicular to and towards an imaginary line between feet of two tripod legs.
