摘要： A reality capture device configured to perform a measuring process for generating a digital representation of an environment comprising a body defining a first axis, and an imaging unit with one or more 2D cameras configured to provide 2D image data of the environment. The device comprises a ToF camera arrangement configured for capturing 3D point-cloud data of the environment and comprising at least two time-of-flight cameras, wherein each time-of-flight camera comprises a sensor array and one or more laser emitters, the sensor array of each of the time-of-flight cameras having an optical axis and being configured to receive reflections of light pulses emitted by the one or more laser emitters of the respective time-of-flight camera, the time-of-flight cameras being arranged around the first axis so that each sensor array has one or two other sensor arrays as a neighbouring sensor array.
