The top of described guy cable rounds two stands and two ends are fixed on the base plate of the two stands outside by elastic device respectively.
A plurality of and drag-line pulley is one to one installed at the top of described support, and each pulley is provided with race, and drag-line snaps in the corresponding race.
Described pulley is installed on the support of place by an axle.
The camera lens of described photographic means makes progress and deflection the place ahead or rear, the optical axial of its camera lens or vertical interlaced vertical with drag-line.
Described photographic means can be with respect to tested pin motion.
The two ends of described drag-line directly are fixed on the top of two supports, and drag-line adopts resilient material to make.
Described each top of the trellis is provided with clip slot, and the two ends of drag-line are fixed in the clip slot.
The camera lens of described photographic means makes progress and deflection the place ahead or rear, the optical axial of its camera lens or vertical interlaced vertical with drag-line.
Between described two supports an intermediate support can be set, the centre position of drag-line is fixed by this intermediate support.
Described measurement of curved surface device can be used for measuring the curved surface of sole curved surface, other part curved surfaces of the human body except that the sole curved surface or human body other objects in addition.
Compared with prior art, advantage of the present utility model is: owing to adopted above-mentioned structure, measurement of curved surface measurement device efficient of the present utility model and measuring accuracy height, with low cost.

[embodiment]
See also Fig. 1 and Fig. 2, first kind of embodiment of the utility model institute measurement of curved surface device comprises base plate 10, be vertically mounted on two on the base plate 10 tabular supports 7 that are parallel to each other, walk around the top of two stands 7 and two ends and be fixed on a plurality of compact arranged drag-line 1 on two stands 7 outside base plates 1 by elastic devices such as springs 8 respectively, be installed in the photographic means 3 of drag-line 1 below, a plurality of and above-mentioned drag-line 1 pulley 6 is one to one installed at the top of its medium-height trestle 7, described drag-line 1 snaps in the race of corresponding pulley 6 at support 7 tip positions, and spring 8 also can be other elastic device.Above-mentioned pulley 6 can guarantee the direction of drag-line 1, and reduces its motion wearing and tearing, and above-mentioned a plurality of pulley 6 can be installed on the support 7 by an axle 5.
When not measuring use, each drag-line 1 is tight state under the pulling force effect of two ends spring.When tested pin 2 is stepped on the drag-line 1 between two stands 7, human body weight is by the bottom of tested pin, be distributed on the drag-line 1 of some, make these drag-lines 1 be tightened in the bottom surface of tested pin, the contour curve of every drag-line 1 and tested pin corresponding site matches, and reflects the contour curve in the cross section of tested foot plate surface respective amount.At this moment, start photographic means 3, the curve shape of these drag-lines 1 is converted to photo by photographic means, and the input computing machine obtains the bottom curved surface data of tested pin by the further analysis of corresponding software do.
It should be noted that, in above-mentioned measuring process, the fore-and-aft direction of tested pin should be vertical substantially with drag-line 1, the camera lens of photographic means 3 makes progress and deflection the place ahead or rear, make the optical axial and drag-line 1 vertical or vertical interlaced of its camera lens, certainly, also can be by optical device, for example reflective mirror achieves the above object.Simultaneously, in order to improve the precision of measurement, photographic means is moved with respect to tested pin.
As shown in Figure 3, the distance between two parallel brackets 7 is widened, and an intermediate support 4 is set between two stands 7, this intermediate support 4 is provided with clip slot 9, and the middle part of the drag-line 1 that can be fixed and clamped can be measured the sole curved surface of left and right sides bipod so simultaneously.Its measuring principle is identical with the principle of measuring a pin, does not repeat them here.
Second embodiment of the utility model measurement of curved surface device please refer to Fig. 4 and Fig. 5, it also comprises base plate 10, be vertically mounted on two on the base plate 10 tabular supports 7 that are parallel to each other, a plurality of compact arranged drag-line 1, be installed in the photographic means 3 of drag-line 1 below, wherein drag-line 1 adopts resilient material to make, the top of each support 7 is provided with a plurality of clip slots 9, in order to fixing corresponding drag-line 1 two ends.
When not measuring use, each drag-line 1 is tight state under the pulling force effect of two ends spring.When on the tested drag-line of riding between two stands 71, obtain the curve shape of corresponding drag-line equally by photographic means 3, finally by obtaining the bottom curved surface data of tested pin after handling.
As shown in Figure 6, the distance between two parallel brackets 7 is widened, and an intermediate support 4 is set between two stands 7, its clip slot 9 compresses the middle part of drag-line 1 equally, then can measure the sole curved surface of left and right sides bipod simultaneously.
Listed above is two embodiments measuring the curved surface of telling somebody what one's real intentions are, and the utility model can also be measured other part curved surfaces of human body except that the sole curved surface or the curved surface of human body other objects in addition.
