The method for optical three-dimensional surveying using an intraoral camera, wherein the intraoral camera provides that a 3D image is created from at least one of the 2D recorded images or from at least one of the sequences, and wherein a plurality of all the 2D recorded images andor sequences created in a first operating mode are used to create at least one overall 3D image. When the determination module determines that a reply result corresponding to one of the transmission packets matches a corresponding expected reply result, the controller continues to transmit another one of the transmission packets to the network and to detect a reply result corresponding to said another one of the transmission packets. A user input interface is operable to select list items for activation, and a control unit is configured to present only the first subset responsive to a command on the user input interface to present the item list. The video is enhanced using the best matching patch in the related image for each identified patch in the video. In the third position, the module can be inserted into the computer and when the lever and cam assembly is moved back to the second position, the second lobe locks the module in the computer.
