Abstract
The invention relates to a front lens focusing transmission structure of a portable self-adaptation image three-dimensional reestablishing instrument. The transmission structure comprises a square sliding plate, a lens installing plate and a fixing base. The left end and the right end of the square sliding plate are fixedly connected with two parallel long-strip-shaped swallow tail sliding blocks respectively, and the fixing base is provided with two parallel long-strip-shaped swallow tail sliding grooves in a matched mode. A rotating shaft is connected with at least one cylindrical bevel gear, the lower end of the square sliding plate is provided with at least one linear long-strip-shaped screw rack, and the cylindrical bevel gear is right meshed with the linear long-strip-shaped screw rack. A lens is transmitted and adjusted to carry out focusing through meshing of the cylindrical bevel gear and the linear long-strip-shaped screw rack matched with each other, the structure is compact, the occupied space is small, and the size of the whole machine is more compact and reasonable. Focusing of the lens is adjusted through sliding between the long-strip-shaped swallow tail sliding block and the long-strip-shaped swallow tail sliding groove matched with each other, the transmission precision is improved, and assembling is simplified.
Description
Technical field
The present invention relates to optical imaging field, particularly a kind of camera lens prefocusing drive mechanism of portable self-adapted 3-dimensional reconstruction instrument.
Background technology
Three-dimensional imaging and measuring system are known, general in order to obtain the 3D shape of object, are the 3D shape of its physical size ideally.Such imaging and measuring system are divided into two classes substantially: 1) surface-contact system: 2) optical system.Optical system is further divided into again laser triangulation, structured lighting, and More interferes, the different systems such as three-dimensional imaging and travel-time measurement.
The method that More interferes is accurate, but expensive and consuming time: the method for three-dimensional imaging need to two cameras or the image of obtaining that carries out taking pictures for twice compare, obtain the three-dimensional surface of object; Travel-time mensuration is measured the time of laser from the relevant every point reflection of object, and it need to have expensive laser scanning transmitter and receiver.
The assisted focused drive mechanism complexity of coherent source of the prior art, or need expensive equipment, or need to reach object by the assembling of more complicated.
Summary of the invention
Technical matters to be solved by this invention is to provide the camera lens prefocusing drive mechanism of the portable self-adapted 3-dimensional reconstruction instrument that a kind of cost is low and mechanism is compact, solves existing equipment complex structure, assembles difficult problem.
Technical scheme
A kind of camera lens prefocusing drive mechanism of portable self-adapted 3-dimensional reconstruction instrument, comprise square slide plate, be fixedly connected on camera lens installing plate and the fixed pedestal of square nose, two ends, square slide plate left and right are fixedly connected with respectively two strip dovetail slide blocks that are parallel distribution, on fixed pedestal, be provided with matchingly two strip dovetail chutes that are parallel distribution, thereby square slide plate slides before and after sliding in fixed pedestal by strip dovetail slide block in strip dovetail chute;
On described fixed pedestal, be also provided with a turning axle, this turning axle be arranged on described square slide plate under, and be fixedly connected on the downside of described strip dovetail chute by pair of bearings; On described turning axle, be connected with at least one cylindric spiral gear, in the lower end of described square slide plate, match and be provided with at least one length strip helical rack directly over cylindric spiral gear, cylindric spiral gear just in time engages with length strip helical rack; One end at described turning axle is also provided with a knob.
Further, on described knob, be provided with a stop knob.
Beneficial effect
The present invention engages transmission adjustable lens by the cylindric spiral gear of mutual coupling with length strip helical rack and focuses on, and compact conformation, takes up room little, makes the volume compact and reasonable more of complete machine.Adjust lens focus by the slip between strip dovetail slide block and the strip dovetail chute of mutual coupling, improved transmission accuracy, simplified assembling.
