Method of determining a digital 3D representation of a person by means of a 3D scanning device, wherein the method comprises the following steps: - provision of a 3D scanning device in which a recording space is surrounded by wall elements (201, 202); - recording of digital 2D images of a person to be scanned in the recording space from different recording directions using camera modules which are arranged distributed over the wall elements (201, 202); - projecting a projection pattern onto the person to be scanned in the recording space by way of one or more projectors which are arranged on the wall elements (201, 202); - recording of further 2D images of the person to be scanned with the hereon projected projection pattern in the recording room from the different recording directions with the aid of camera modules; and - determining a 3D representation of the person to the scanned by way of an evaluation device (24; 28) which is connected to the camera modules and set up using digital image analysis to evaluate the digital 2D images and the further 2D images and to determine the digital 3D representation of the person to be scanned, wherein determining the digital 3D representation comprises the following steps: - determining a digital initial representation of the person to be scanned; - recording a selection for a sample phenotype; - provision of a digital 3D representation for the selected sample phenotype; and - determining the digital 3D representation of the person to be scanned in that the digital 3D representation of the selected sample phenotype is iteratively adapted taking into account the digital initial representation. - provision of a 3D scanning device in which a recording space is surrounded by wall elements (201, 202); - recording of digital 2D images of a person to be scanned in the recording space from different recording directions using camera modules which are arranged distributed over the wall elements (201, 202); - projecting a projection pattern onto the person to be scanned in the recording space by way of one or more projectors which are arranged on the wall elements (201, 202); - recording of further 2D images of the person to be scanned with the hereon projected projection pattern in the recording room from the different recording directions with the aid of camera modules; and - determining a 3D representation of the person to the scanned by way of an evaluation device (24; 28) which is connected to the camera modules and set up using digital image analysis to evaluate the digital 2D images and the further 2D images and to determine the digital 3D representation of the person to be scanned, wherein determining the digital 3D representation comprises the following steps: - determining a digital initial representation of the person to be scanned; - recording a selection for a sample phenotype; - provision of a digital 3D representation for the selected sample phenotype; and - determining the digital 3D representation of the person to be scanned in that the digital 3D representation of the selected sample phenotype is iteratively adapted taking into account the digital initial representation. - determining a digital initial representation of the person to be scanned; - recording a selection for a sample phenotype; - provision of a digital 3D representation for the selected sample phenotype; and - determining the digital 3D representation of the person to be scanned in that the digital 3D representation of the selected sample phenotype is iteratively adapted taking into account the digital initial representation.
