摘要： 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.
