The article is devoted to the development of a scanning device for prompt and accurate determination of the shape of small-sized objects of cultural heritage, for example, found during archaeological excavations. The structured lighting device includes: a data processing server, a Raspberry PI microcomputer, two servos, a television camera and a line laser. Data packets are formed on the microcontroller, which are sent to a remote server via the http protocol. The server processes the received data packets in the David-laserscanner environment and their further combination in the Meshlab environment. The result of processing is a 3D model of the scanned object in obj format. On the basis of analytical calculations, the optimal values of the parameters of the scanning device have been determined, at which both high speed and acceptable quality of the resulting model are achieved, taking into account its design and selected components. A mockup of a scanning device has been developed and manufactured, which makes it possible to quickly obtain 3D-models of objects with dimensions up to 100Г—100Г—140 mm, and the results of its experimental study are presented.
