In a method for collecting via a video camera three-dimensional surface information in dental applications, a tape strip is applied to a tooth surface to provide a distance reference or standard for use by a computer in analyzing the video data to determine actual distances. The tape strips are additionally provided with identification markings identifying the type of surfaces and the teeth to which the tape strips are attached. Slots are provided for facilitating observation and digitization of tooth surface data, the side walls of the slots also serving as shoulders for guiding a contour tracing instrument. Various devices are disclosed for facilitating the attachment of the tape strips to the tooth surfaces.
