Description
Technical field
The utility model relates to optical imaging field, particularly after a kind of light source of portable self-adapted 3-dimensional reconstruction instrument, focuses on drive mechanism.
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.
Utility model content
Technical problem to be solved in the utility model focuses on drive mechanism after being to provide the light source of the low and portable self-adapted 3-dimensional reconstruction instrument that mechanism is compact of a kind of cost, solves existing equipment complex structure, assembles difficult problem.
Technical scheme
After the light source of portable self-adapted 3-dimensional reconstruction instrument, focus on a drive mechanism, comprise fixed pedestal, trapezoidal screw, with trapezoidal screw periphery be spirally connected the guiding nut of transmission, be fixedly connected with guiding nut and can be along the axially movable light source sliding seat of trapezoidal screw by the promotion of guiding nut; Described trapezoidal screw is rotatably supported on described fixed pedestal by the first transverse bearing in the end in left side, end on right side is connected with a motor by a shaft coupling, is rotatably supported on described fixed pedestal between the two above-mentioned near right end place by the second transverse bearing; On described fixed pedestal, be also fixedly installed two line slideways, two line slideways are all parallel to the axis direction of described trapezoidal screw, and are the both sides that are distributed in symmetrically described trapezoidal screw; Described light source sliding seat is bearing on described line slideway movably, and when work, described light source sliding seat slides along line slideway direction under the promotion of described guiding nut; On the side of described light source sliding seat, be provided with a magnetic railings ruler read head, on the relevant position of described fixed pedestal, be provided with matchingly a magnetic railings ruler.
Further, described motor is servomotor.
Beneficial effect
The utility model drives by servomotor trapezoidal screw and the guiding nut transmission that transmission accuracy is high, and accurately controls the position of light source sliding seat of carrying light source by magnetic railings ruler read head and magnetic railings ruler, makes the measuring accuracy of the method that More interferes higher.Compact conformation, takes up room little simultaneously, makes the volume compact and reasonable more of complete machine.
