Detailed description of the invention
Fig. 1 has been the block chart of the input system of the three-dimensional hand-written inputting method of the present invention.Fig. 2 to Fig. 8 is the schematic diagram of the three-dimensional hand-written inputting method of the present invention.Fig. 9 A, 9B are the flow chart of the three-dimensional hand-written inputting method of the present invention.
As it is shown in figure 1, the three-dimensional hand-written inputting method of the present invention is at least to realize by image acquisition unit 10, display unit 20, arithmetic element 30 and a storage element 40.Image acquisition unit 10 is connected to arithmetic element 30, and display unit 20 is also connected to arithmetic element 30.The image that image acquisition unit 10 captures is transferred into arithmetic element 30 and is analyzed, and display unit 20 can show that arithmetic element 30 is intended to the content of display, for instance the content of input.Storage element 40 stores a lteral data storehouse.The present invention does handwriting input with the gesture of personnel, and the motion track that gesture produces can compare with the lteral data storehouse in storage element 40, and the content being intended to input can be shown by display unit 20.
As shown in Fig. 2 to Fig. 8, one personnel 100 stand within the image capture scope 15 of image acquisition unit 10, image acquisition unit 10 can capture the image of personnel 100 continuously, and the image captured is transferred into arithmetic element 30 and is analyzed, and the result of analysis is shown in display unit 20.
As shown in Figure 2, when personnel 100 stand in image capture scope 15, image acquisition unit 10 captures the image of personnel 100, and it is sent to arithmetic element 30, arithmetic element 30 judges that the hands 102 of personnel 100 (is for the right hand in the present embodiment, but be not limited to the right hand, left hand can also) whether lift.
As shown in Figure 3, when the hands 102 of personnel 100 lifts, arithmetic element 30 judges that personnel 100 are intended to carry out word input, the now coordinate of the hands 102 of arithmetic element 30 record keeping personnel 100, and this setting coordinate is become a reference coordinate, arithmetic element 30 judges the moving direction of the hands 102 of personnel 100 according to reference coordinate.
As shown in Figure 4, when the hands 102 of personnel 100 starts mobile, arithmetic element 30 judges the moving direction of the hands 102 of personnel 100 by the image that image acquisition unit 10 transmits.When the hands 102 (direction towards close to image acquisition unit 10) forward of personnel 100 is mobile, arithmetic element 30 judges into personnel 100 and is intended to start to write.
As it is shown in figure 5, when arithmetic element 30 judges that personnel 100 are intended to start to write, image acquisition unit 10 captures the motion track of the hands 102 of personnel 100, and is sent to arithmetic element 30, and this motion track can synchronously be shown on display unit 20.
As shown in Figure 6, when the hands 102 of personnel 100 is backward (away from image acquisition unit 10), arithmetic element judges that personnel stop writing.Now this motion track and the lteral data storehouse being stored in storage element 40 are carried out right by arithmetic element 30, and will be closest to the text importing of this motion track on display unit 20.Another kind of kenel be by the several text importing close with this motion track on display unit 20, select for personnel 100.When arithmetic element 30 judges that personnel 100 stop writing, even if personnel 100 move hands 102, arithmetic element 30 is only considered as simple movement for its motion track, without doing the judgement write, without capturing its motion track.When the hands 102 of personnel 100 forwards moves once again, arithmetic element 30 just can judge into personnel 100 once again and be intended to start to write.
As shown in Figure 7, Figure 8, when hands 102 is put down by personnel 100, arithmetic element 30 judges that personnel 100 are intended to terminate word input.
Fig. 9 A and 9B represents the three-dimensional hand-written inputting method of the present invention, after personnel enter image capture scope, the image of acquisition personnel, then judge whether the hands of the personnel in image lifts, if the hands of personnel lifts, then enter text input mode, in text input mode, if the hands of personnel moves forward, expression personnel start to write, now capture the motion track of the hands of personnel, when the hands of personnel is moved rearwards by, expression personnel stop writing, so, the motion track captured is compared with the word in literal pool, then by text importing in display unit.When handing down of personnel, terminate text input mode.When personnel leave image capture scope, stop image capture.
Image acquisition unit 10 can be the sensor of two dimension photography, such as general network camera, industrial photography machine etc., arithmetic element 30 judges that by the change of the size of the image of the hands 102 of personnel 100 hands 102 of personnel 100 is close to or away from image acquisition unit 10.
Image acquisition unit 10 can also be the sensor of 3-D photography, such as camera adds infrared ray sensor, stereoscopic camera etc., the three-dimensional coordinate of fechtable hands 102, arithmetic element 30 judges that by the change of the three-dimensional coordinate of the hands 102 of personnel 100 hands 102 of personnel 100 is close to or away from image acquisition unit 10.
Although in the above-described embodiment, it is to raise one's hand as the feature starting or terminating text input mode, but the present invention is not limited to this, using other gesture as starting text input mode or terminating also may be used.
In the handwriting sckeme of the present invention, moving forward with hands is judged as starting writing writes, and the hands stopping that being moved rearwards by being judged as starting writing is write, meet intuition and custom that the mankind write, easy to spread with use, and owing to meeting the custom that the mankind use, it is easier to ground is used in device and the game of body-sensing.
