It surveys between device with an angle, image to Image detection to reflect multiple and different visual angles of curved surface determinand SP fills
It puts.The advantages of being detected using plane mirror is that plane mirror does not have curvature, therefore reflects the shadow obtained
Situation as not having deformation, therefore the image in each position of curved surface determinand SP can reach rationally detection accurately
Degree.
In a wherein embodiment, Fig. 5 to Fig. 8 is please referred to, the side of the first embodiment of mirror is expanded for image in the present invention
Face schematic diagram (one), front schematic view (one), side schematic view (two), front schematic view (two).
As shown in Fig. 5 and Fig. 6, in the present embodiment, on the first detection platform A2, plane mirror W11, W12,
W13, W14 are averagely set to respectively on the four direction of an opening side, the first grabbing device 22 by the curved surface determinand SP by
The opening is placed in, and the image at tetra- visual angles of curved surface determinand SP is reflected by the plane mirror W11, W12, W13, W14.Such as
Shown in Fig. 5 and Fig. 6, plane mirror W11, W12, W13, W14 are set to the four direction of curved surface determinand SP, in addition to facing
Other than the block A of first image detection device 23, block C on plane mirror W11 by obtaining, block G is by plane mirror
Obtained on W12, block E by being obtained on plane mirror W13, block I is on plane mirror W14 then by being obtained.Therefore,
Five blocks of curved surface determinand SP sides can obtain in primary shooting.
It continues, transferring load to the second detection platform B2 in the curved surface determinand SP that the first detection platform A2 shootings are completed carries out separately
The shooting of side.When carrying out opposite side shooting, as shown in Figures 7 and 8, since the second grabbing device 32 is bent by opposite side crawl
Face determinand SP, therefore the image of curved surface determinand SP blocks B can be taken acquirement.It is equally logical in the second detection platform B2
The amplification image that four plane mirrors W21, W22, W23, W24 obtain curved surface determinand SP is crossed, and to be measured for the curved surface
Object SP and the amplification image are shot, and the image of curved surface determinand SP obtained is in addition to facing the second image detection device 33
Block B other than, block D on plane mirror W21 by obtaining, block F by being obtained on plane mirror W22, block H by
Obtained on plane mirror W23, block J on plane mirror W24 then by being obtained, this can be obtained by secondary shooting
Still none obtained image on another hemisphere of curved surface determinand SP.Thereby, curved surface determinand SP wholes are obtained in shooting twice
Image.
In the embodiment that four sides plane mirror W11-W14, plane mirror W21-W24 are set, it is preferred that emphasis is obtain
Image on front side of curved surface determinand SP, for the center of visual zone distance of the image detection device is made to fall within detected curved surface
On centre position, curved surface determinand SP centers have to pass through the aperture position suitable distance, the plane mirror and the image
Angle [alpha] 1 between the shooting direction of detection device should level off to 27 degree of angles, and reasonable value can be 17 degree of angles between 37 degree of angles,
The distance between palpus view plane speculum W11-W14, plane mirror W21-W24 and curved surface determinand SP and the curved surface are treated
Object SP is surveyed to pass through the distance of opening and determine.
In another embodiment, Fig. 9 to Figure 12 is please referred to, the second embodiment signal of mirror is expanded for image in the present invention
Figure.
In the present embodiment, by changing plane mirror E11, E12, E21, E22 and the image detection device shooting side
Angle between changes capture angle of the image detection device to curved surface determinand SP.In Fig. 9 and Figure 10, due to
Opening of first grabbing device 22 by the whole curved surface determinand SP across the plane mirror E11, E12, therefore can be with
See the image of curved surface determinand SP more rear sides, and obtain in primary shooting hemisphere and rear quarter before curved surface determinand SP
Image.Since image detection device can obtain the image of two blocks in single side plane mirror, the present embodiment must only be set
The image of five blocks can be obtained by putting two plane mirrors.As shown in FIG. 9 and 10, other than block A, Image detection
