Referring to Fig.1, it is first embodiment of the invention, provides a kind of intelligent picture mosaic calculation of fusion shape feature and color
The overall structure diagram of method, such as Fig. 1, it is a kind of fusion shape feature and color intelligent picture mosaic algorithm include extraction chip edges
Characteristic point I；Utilize Edge Feature Points I curve constructions R1；According to similar between curve R1 and different chip edges curve R2
Degree F and color characteristic X is spliced；Restore original image.
Specifically, inventive algorithm is that the Edge Feature Points I of each fragment is configured to curve R1, R2, R3 successively first
Deng curve R1, R2, R3 etc. are built into geometry S according to similarity, and geometry S is that similarity F is appointed as along clockwise
The edge dislocation sequence vector M of direction arrangement, and be segmented according to certain rule, as shown in Figure 2, different colours
Different sections is represented, each edge dislocation vector constitutes the part in a block boundary section, and uses every rotation angle
Come specify each fragment how from it is a kind of layout be moved to another layout, as shown in Figure 3, the home position direction of fragment K
With the direction after rotation θ degree, as previously mentioned, each chip edges are designated as an edge dislocation vector in the direction of the clock
Sequence, if a pair of of edge M1 and M2 are adjacent, M2 is bound to fully be bonded M1, and there are a marginal vectors certainly for it
Sequence is equal to reversed M1 or as M1, so when calculating edge matching, segmentation calculates similarity, finds out most similar
Adjacent block；In the case of there are similar in polylith similarity, color characteristic X is recycled to be compared, as two in Fig. 3 punctuate it
Between shape punctuate respectively in Fig. 4 and Fig. 5 two between shape can match, but the apparent colors of Fig. 4 and Fig. 5 differ
Sample, therefore select Fig. 4, finally goes back original image, completes picture mosaic, i.e., is carried out between different fragments using fragment contour and color characteristic
Measuring similarity improves image restoring precision.
Wherein, similarity F is calculated using following formula：
Wherein, d is the metric function on S, and A and B are two continuous boundary curves on S, and R is junction curve, and t is to become
Amount, A and B are corresponding with curve R1 and curve R2 respectively, i.e. A:[0,1] → S, B:[0,1] → S, α and β are the two of unit interval
A heavy parameterized function, i.e. α:[0,1] → [0,1], β:[0,1] → [0,1].
Wherein, color characteristic X is calculated using following formula：
D=sqrt { (x1-x2)2+(y1-y2)2}
Wherein, a (x1, y1) and b (x2, y2) is 2 points in plane, and a and b are fragment color measurements point, and d is a and b two
Actual range between point.

604b, and axle bed 303 further includes magnetic force block slot 303a and magnetic force block axis hole 303b, while magnetic force clamping block 605 further includes magnetic
Power block shaft 605a and damper lock-out protrusion 605b.Specifically, when wear ring 604 is embedded in axle bed 303, it is set to wear-resisting
It the damping projection 604a of 604 outer surface of ring and is set to relatively rotate between the intensive damping compact district of 303 inner surface of axle bed and produces
Raw damping cooperation, magnetic force clamping block 605 is set in magnetic force block slot 303a, and magnetic force block axis hole 303b and magnetic force block shaft 605a
Between shaft be arranged, therefore magnetic force clamping block 605 is located in magnetic force block slot 303a that pivoting, i.e. magnetic force clamping block can occur
605 one end can tilt upward or downward；Under normal condition, the damper lock-out for being set to 605 inner surface of magnetic force clamping block is convex
605b and the inconsistent cooperations of damping projection 604a are played, therefore cannot be relatively rotated (i.e. between wear ring 604 and axle bed 303
Lock-out state), and when 605 one end of magnetic force clamping block is upturned, between damper lock-out protrusion 605b and damping projection 604a
It is detached from, there is no mutually conflict active forces, therefore can relatively rotate between wear ring 604 and axle bed 303 and (unlock shape
State).
With reference to Figure 20, pivot pin 304 further includes quill 304a, the outer limiting slot 304b of pivot pin, limits in pivot pin in the present embodiment
Position slot 304c and pivot pin screw thread 304d.Specifically, quill 304a is with hollow sleeve structure, the outer limiting slot of pivot pin
304b is respectively arranged at outside and the inner surface of quill 304a with limiting slot 304c in pivot pin, and pivot pin screw thread 304d is set to
The outermost sides quill 304a.Based on above-mentioned, also there is following matching relationship herein：Wear ring 604 is sheathed on quill 304a
On, the two is locked by coordinating between limiting slot 304b outside limit protrusion 604b and pivot pin, cannot be relatively rotated, next is led
Be embedded in quill 304a to sleeve 603, therebetween by limiting slot 304c in guide and limit protrusion 603b and pivot pin it
Between realize locking, can not relatively rotate；After completing all assembly, briquetting 602a is limited by block 601, passes through gear
The screw thread that 601 inside of block is arranged is realized with the 304d cooperations of pivot pin screw thread.
It show the schematic cross-sectional view of magnetic force lock set 600 in this implementation with reference to Figure 21, realizes locking and unlock
Process substantially：Above-mentioned matching relationship is pressed when completing 600 component of magnetic force lock set, and after being left and right symmetrically arranged, magnetic force locking
Block 605 is located at the top of magnetic force switch block component 602, herein it should be noted that magnetic force clamping block 605 and magnetic force switch block component 602
Magnetic force is carried, and is sequentially distributed opposite with 605 magnetic force of magnetic force clamping block and identical polar magnetic on magnetic force switch block component 602
Power, by the way that the range of polarity magnetic force distribution on magnetic force switch block component 602, the range of control locking and unlock is arranged.Lock-out state
When lower, spring 602d is in normal condition (being not compressed), at this time magnetic force clamping block 605 and about 602 magnetic force switch block component point
Cloth is out-phase magnetic pole, and the two has attraction, therefore damper lock-out protrusion 605b and damping projection 604a phases under magneticaction
It mutually contradicts and realizes locking.Under unlocked state, by the above-mentioned briquetting 602a of Manual press, i.e. compressed spring 602d, magnetic force at this time
Swivel becket 602b is gradually embedded in pilot sleeve 603, and guide pad 602c enters in directive slide track 603a, to magnetic rotation ring
602b, which is directed to, to rotate, due to being sequentially distributed and phase opposite with 605 magnetic force of magnetic force clamping block on magnetic force switch block component 602
The magnetic force of same polarity, when having same pole both to turn to, under repulsion effect, shaft rotation occurs for magnetic force clamping block 605
Dynamic one end is upturned, and damper lock-out protrusion 605b is detached from damping projection 604a, completes unlock.Herein it should be noted that
The symmetrically arranged purpose in the present embodiment both ends is need to press above-mentioned briquetting simultaneously by both ends to realize that unilateral side can not unlock
When 602a, the compression to spring 602d could be realized, can unlock.Therefore between briquetting 602a and magnetic rotation ring 602b
The elastic force for being also provided with screens spring 602e, and meeting spring 602d is more than the elastic force of screens spring 602e, when unilateral side presses,
Screens spring 602e can be compressed, and spring 602d is not compressed, but when both sides simultaneously press when, screens spring 602e not by
Power at this time after the symmetrical spring 602d forced compressions in both ends, realizes unlock.
