Specific embodiment

In the following, the utility model is specifically described by illustrative embodiment.It should be appreciated, however, that not having In the case where being further discussed below, element, structure and features in an embodiment can also be advantageously incorporated into other implementations In mode.

In the description of the present invention, it should be noted that term "inner", "outside", "upper", "lower", "front", "rear" etc. The orientation or positional relationship of instruction is positional relationship based on the figure, is merely for convenience of description the utility model and simplification Description, rather than the device or element of indication or suggestion meaning must have a particular orientation, constructed and grasped with specific orientation Make, therefore should not be understood as limiting the present invention.In addition, term " first ", " second ", " third " are only used for description mesh , it is not understood to indicate or imply relative importance.

The utility model proposes a kind of 3D scanning means, multiple to be set to including the first turntable 2 for placing scanning object The second turntable 7 around first turntable 2, second turntable 7 is equipped with camera unit 1, between multiple second turntables 7 Every setting.

With reference to Fig. 1,3D scanning means described in the utility model by multiple spaced second turntables 7 and is taken the photograph As the setting of unit 1, it is only necessary to single rotary scanning, and be not easy to block in scanning process.

First turntable 2 for placing scanning object, place wait sweep by settable slip-proof element on first turntable 2 It retouches and is slided between object and first turntable 2, first turntable 2 is connected with the first driving unit (not shown), First driving unit is preferably motor, the slowly rotation of the first turntable 2 is controlled, so that scanning object be driven slowly to revolve Turn.

Second turntable 7 is set to around first turntable 2, can be rotated around first turntable 2, described second turn Platform 7 is connected with the second driving unit 3, and second driving unit 3 is preferably motor, to control second turntable 3 slowly It can be operated synchronously when rotating, adjustable angle between multiple second turntables 7, but scanning, keep relative position constant, So as to the Model Fusion in later period.

The camera unit 1 is set on second turntable 7, can be followed the rotation of second turntable 7 and be rotated, each The camera unit 1 is equipped on second turntable 7, as shown in fig. 1, the present embodiment is preferably two, is taken the photograph described in two It, can be according to the needs of shooting, two institutes as form an angle setting of the unit 1 on the rotational plane of first turntable 2 It states in the angle setting between 1~180 ° between camera unit 1, but in scanning, can control the individually rotation of the first turntable 2 Turn, or multiple second turntables 7 of control move synchronously, and keep the relative position between multiple second turntables 7 constant, So as to the Model Fusion in later period, the camera unit 1 can be used with camera function mobile phone or other with camera function Digital product replaces, and use is more flexible, and cost is lower.
