A method is provided that involves mounting a transmit block and a receive block in a LIDAR device to provide a relative position between the transmit block and the receive block. The method also involves locating a camera at a given position at which the camera can image light beams emitted by the transmit block and can image the receive block. The method also involves obtaining, using the camera, a first image indicative of light source positions of one or more light sources in the transmit block and a second image indicative of detector positions of one or more detectors in the receive block. The method also involves determining at least one offset based on the first image and the second image. The method also involves adjusting the relative position between the transmit block and the receive block based at least in part on the at least one offset.

The following relates generally to light detection and ranging (LIDAR) and artificial intelligence (AI). In some embodiments, a system: receives LIDAR data generated from a LIDAR camera; measures a plurality of dimensions of a room of the home based upon processor analysis of the LIDAR data; builds a 3D model of the room based upon the measured plurality of dimensions; receives an indication of a proposed change to the room; modifies the 3D model to include the proposed change to the room; and displays a representation of the modified 3D model.

A reality capture device for generating a digital three-dimensional representation of an environment enables an object within an infrastructure to be surveyed or detected. The reality capture device is compact and easy to use, allowing for fast and reliable capture. The reality capture device can be carried and moved by a mobile carrier, particularly a person, robot or vehicle, and can be moved during a measuring process for generating a digital representation of an environment. The mobile reality capture device includes a localization unit for providing a simultaneous localization and mapping functionality, a laser scanner, and a camera unit. The mobile reality capture device is configured to be carried by a user through the room. The room is surveyed during the movement of the mobile reality capture device. The data from the laser scanner and the camera unit are referenced to each other by means of the localization unit.

A Slope Stability Lidar that directs a beam of optical radiation into an area on a point by point basis, each point having an elevation and azimuth and a processor that acquires data and processes the data to compile direction data, range data and amplitude data for each point, segments the acquired data into blocks of data defining a voxel, averaging the acquired range data within the voxel to produce a precise voxel range value for each voxel, comparing voxel range values over time to identify movement and generating an alert if movement exceeds a threshold.

An erecting system and a binocular telescope for laser ranging. The erecting system includes a roof half penta prism, a beam splitting prism and an isosceles prism. The beam splitting prism is positioned between the roof half penta prism and the isosceles prism. The beam splitting prism is formed by bonding two right-angle prisms. A beam splitting film is arranged on a bonding surface of the two right-angle prisms. The erecting system not only has simple structure and small occupation volume, but also is convenient in use, can realize the binocular observation and targeting at a measured object, and can display the distance of the measured object in real time in the field of view while observing the object.
