Embodiment
Below in conjunction with accompanying drawing principle of the present invention and characteristic are described, institute gives an actual example and only is used to explain the present invention, is not to be used to limit scope of the present invention.
The present invention provides a kind of easy clock clock hand position detecting device and utilizes this device to carry out the method for clock pin position probing.
As one side of the present invention, clock clock hand position detecting device comprises hour hands index dial 100, minute hand index dial 200, identification plate 300 and at least one pair of camera 400.With Fig. 1 is example, on the end that the movement 101 that a pair of camera 400 is positioned at clock and the hour hand axle 102 of clock join, is symmetrically distributed in the both sides of hour hand axle 102; Identification plate 300 is assemblied on the end that movement 101 and hour hand axle 102 join, and identification plate 300 is provided with the hole 600 that all is complementary with camera quantity and position; Hour hands index dial 100 is assemblied on the hour hand axle 102, and minute hand index dial 200 is assemblied on the minute hand shaft 103; Hour hands index dial 100 is corresponding with two holes 600 of identification plate 300 respectively with minute hand index dial 200.Also dividing respectively on hour hands index dial 100 and the minute hand index dial 200 has the zone that is used to represent the clock scale at least more than two, and identifying respectively in the different zone of identical graduation dish has the various colors sequence.
Technical scheme of the present invention has promptly realized a kind of grandfather clock clock needle detecting device simple in structure, low-cost, easy-to-install.As shown in Figure 3; Two holes 600 on a pair of camera 400, the identification plate 300 and hour hands/minute hand index dial relative set; Camera 400 is taken image on hour hands/minute hand index dials detecting clock pin position through the hole on the identification plate 300 600, and then judges clock punctual timing property.
As shown in Figure 1; When occurring hour hands 104 in the shooting process and hinder the top cameras to the shooting of minute hand 105; Can obtain the temporal information that minute hand is represented through another camera picture shot that is positioned at the below; Therefore in order to improve the accuracy of this clock needle detecting device judged result, can be at hour hand axle 102 a plurality of cameras circumferentially are set.
Hour hands of the present invention/minute hand index dial is that a kind of method of color showing numeral of utilizing realizes; Concrete implementation can be referring to Fig. 2: if hour hands index dial and minute hand index dial are circular design; Then can minute hand index dial 200 be divided into 60 parts of sector regions, hour hands index dial 100 is divided into 12 parts of sector regions; And each sector region is all distinguished with the various colors sequence; Simultaneously, for further simplified image processing procedure, be convenient to image recognition, technical scheme of the present invention also is provided with spacing identification line 106 between each sector region.
As shown in Figure 4, the hole of identification plate 300 also comprises the attribute block 301 that is used to locate, and attribute block 301 places hole 600 central authorities of identification plate 300, and is positioned at the outward flange of hour hands index dial 100.In addition, in the horizontal direction, the length of attribute block 301 is less than the width of minute hand index dial 200 each sector region.Thereby guarantee the definite pending image-region that computing machine can be correct.
As another aspect of the present invention, great bell and its outer computer that above-mentioned clock hand position detecting device is installed cooperatively interact, and accomplish clock pin position probing according to step as shown in Figure 7, and be specific as follows:
Step 1: camera 400 is taken the image of hour hands index dial 100 and minute hand index dial 200;
Step 2: computing machine reads image;
Step 3: remove the background color on the image;
Step 4: confirm pending image-region;
Step 5: the colour sequential that reads pending image-region;
Step 6: convert colour sequential into the time scale value.
At first; The image that utilizes the interior camera of pick-up unit 400 shooting hour hands index dials 100 and minute hand index dial 200 at a time to go up, the relative position that can adjust identification plate 300 and hour hands/minute hand index dial before this in advance guarantees the integrality of photographic images.Secondly, the image that photographs is sent to the outside computing machine of pick-up unit and carries out Flame Image Process; For the ease of image recognition, computing machine receives behind the image then the passing threshold means and removes the picture background color.At last, confirm image-region pending in the picture, and convert colour sequential into the time scale value behind the colour sequential in obtaining above-mentioned zone.
Above-mentioned steps 4 is confirmed pending image-region through scanning flag piece 301.In addition, after scanning attribute block 301, also can further confirm pending image-region through sweep spacing tag line 106.
With minute hand index dial shown in Figure 5 200 is example; If represent a certain minute hand scale with the dark red colour sequential of Huang; Represent the edge line 107 of index dial with black, then can realize the minute hand position probing in such a way: computer scanning attribute block 301 promptly begins to detect scanning from bottom to top after confirming good pending image-regions; Behind the edge line 107 that detects the black line representative, promptly finish scanning, so far obtained to take the colour sequential of representing this minute hand scale constantly.
Likewise, after scanning attribute block 301, the pending image-region of scan clock index dial 100 obtains the colour sequential that hour hands scale is constantly taken in representative from top to bottom.According to the corresponding relation between predefined colour sequential and the time scale value, convert above-mentioned two groups of colour sequentials into the time scale value respectively at last, to judge punctual timing property.
If image taking constantly, attribute block 301 is positioned at the centre position of minute hand scale sector region, and is as shown in Figure 6.After then can scanning the position of confirming the spacing identification line, obtain colour sequential through scanning tag line left/right image again.
The above is merely preferred embodiment of the present invention, and is in order to restriction the present invention, not all within spirit of the present invention and principle, any modification of being done, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
