Abstract
The invention relates to an optical scanning device of an integrated structure, belongs to the field of reverse engineering and relates to visual three-dimensional measuring systems. The optical scanning device of the integrated structure is characterized in that the optical scanning device of the integrated structure comprises a central processing module, a projecting module, a left side image collecting module, a right side image collecting module and a data transmission module. The central processing module controls the projecting module to project structural light to a detected object, synchronous collection is carried out on the detected object through the two side image collecting modules, and the central processing module transmits image information to a computer through the data transmission module after acquiring the image information, so that the computer can carry out processing. According to the optical scanning device of the integrated structure, only one central processing module is used for controlling scanning, and thus scanning speed is improved; the data transmission module is adopted, data transmission with the computer is carried out only through one data line, and thus complexity of mounting the system is reduced.
