Description
Technical field
The utility model 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 laser from the time of the relevant every point reflection of object, and it need to have expensive laser scanning transmitter and receiver.
The assisted focused drive mechanism of coherent source of the prior art is complicated, or needs expensive equipment, or need to reach object by the assembling of more complicated.
Utility model content
Technical problem to be solved in the utility model is to provide the camera lens prefocusing drive mechanism of the portable self-adapted 3-dimensional reconstruction instrument of a kind of cost Di Qie mechanism compactness, 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 by pair of bearings, be fixedly connected on the downside of described strip dovetail chute; 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 and length strip helical rack just in time mesh; 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 utility model meshes transmission adjustable lens to focus on by cylindric spiral gear and the length strip helical rack of mutual coupling, and compact conformation, takes up room little, and the volume that makes complete machine is compact and reasonable more.By the strip dovetail slide block of mutual coupling and the slip between strip dovetail chute, adjust lens focus, improved transmission accuracy, simplified assembling.
