Abstract
The invention discloses a gesture recognition device and a gesture recognition method applicable to early childhood education. The gesture recognition device comprises a PC (personal computer), a camera, a tailor-made touch panel and a height-adjustable support. The tailor-made touch panel can be a transparent hard plastic plate, is arranged on the support not far away from the camera, is not connected with the camera and the PC, and is not arranged too high (for children use). A multidirectional coordinate system used in the gesture recognition method is engraved on the touch panel, and palm shapes are engraved at joints of an original point, a circle drawn by a center length of radius and direction axes. The coordinate system is usually built as an eight-directional coordinate system, and the upper, the upper right, the right, the lower right, the lower, the lower left, the left and the lower left directions are marked as 1, 2, 3, 4, 5, 6, 7 and 8 respectively. Compared with the prior art, the gesture recognition device has the advantages of simple structure and high applicability; the gesture recognition method matched with the device is quick in operational speed, high in recognition efficiency, standard in operation to some extent and high in speed.
Description
Technical field
The present invention relates to computer realm, specifically relates to a kind of apparatus and method of the gesture identification for preschool education.
Background technology
At present, computing machine is in the rapid expansion of modern society's impact, input mode becomes more and more succinctly, more hommization, people constantly propose new requirement and challenge to the level of man-machine interaction and quality, a lot of local all mouses before replacement gradually and keyboard input, the modes such as employing such as phonetic entry, online handwriting input, gesture input, this meets the target of multi-mode human-machine interface technology research, makes user can facilitate, naturally use the known mode of subclass to use computing machine.
Because gesture has intuitive, naturality, gesture has become a kind of important means of man-machine information interaction.Than the data glove proposing before, mark gesture, natural hand etc., dynamic gesture recognition system based on vision is one of focus of current scientific development, a lot of scholar both domestic and external drops into the research that great enthusiasm is carried out relevant direction, meanwhile, the dynamic gesture recognition system based on vision is also the Main Trends of The Development of current and following gesture recognition system.A kind of dynamically isolated Gesture Recognition based on vision that for example Tsing-Hua University provides, proposed again the regular algorithm of dynamic space-time afterwards for gesture identification, and to 12 kinds of gestures, average recognition rate is up to 97%.
Gesture identification be and speech recognition after a large study hotspot of field of human-computer interaction, in man-machine interaction, application prospect is extensive, still also has some shortcomings.For example to identify cursor of mouse action, conventionally can adopt the mode of dot matrix identification.This mode discrimination is higher, but owing to relating to a large amount of recognizers, process is complicated, and institute's recognition reaction is blunt.And for gesture identification, less demanding to track accuracy of identification, but higher to rate request, therefore with regard to a kind of simply and fast recognition method of needs.Particularly, in preschool education field, not only will accomplish simple high speed, also need gesture identifying device safety, method to design original, applicable child operates.
Summary of the invention
The object of the invention is to have overcome deficiency of the prior art, a kind of apparatus and method of the gesture identification for preschool education are provided, this device is simple and compact, be well suited for child's operation, the method fast operation, recognition efficiency are high, can select as the input method of many preschool education softwares.
In order to solve the problems of the technologies described above, the present invention is achieved through the following technical solutions:
The device of this gesture identification for preschool education is comprised of PC, camera and special touch pad and height adjustable support thereof.The touch pad that this piece is special can make a transparent rigid plastic sheet, be placed in before camera above support nearby, be not connected with camera, PC, do not arrange too high (child's use), on touch pad, be carved with the multi-direction coordinate system using in the method, in initial point and the shape of palm on the intersection point place class of certain length drawn circle and axis of orientation as radius of take.
The direction of the gesture identification for preschool education of this and described matched with devices, comprises the following steps:
(1) select the suitable touch pad of a block size to be placed in before camera, over against camera, suitable by highly arranging, half path length recorded thereon and change in coordinate axis direction;
(2) on screen, take current cursor position as initial point, set up multi-direction coordinate system, this coordinate axis is identical with touch pad change in coordinate axis direction, and length is according to processing in proportion;
(3) in conjunction with radius and the direction of touch pad, in gesture computing module, preset the error angular range between each coordinate direction axle, and the minor increment between terminal point coordinate and the starting point left side;
(4) hand is placed on to touch pad initial point, camera photographic images, processes through Hand Gesture Segmentation and gray scale, obtains current hand gesture location, and and screen on initial point overlap; Then along a direction axle, move hand to circumferential position, the terminal hand gesture location after record move;
(5) whether the distance that judges point-to-point transmission is less than minor increment, if be less than minor increment, this exercise void, stops identification; If be greater than or equal to minor increment, whether error in judgement angle within the scope of the angular error of setting, if not, be null result again, stops judging;
(6) if there is result,, from the photo of taking, judge the direction that gesture moves, calculate distance mobile in coordinate axis, obtain direction and coordinate figure that cursor need to move, and export corresponding actions;
(7) one-off has been identified.Then hand leaves touch pad, is put into initial point, starts action recognition next time, so constantly circulation.
Compared with prior art, the invention has the beneficial effects as follows:
The invention provides a kind of apparatus and method of the input of the gesture for preschool education of simple and fast, compared with prior art, its device is simple, applicability is high, the adjustable height touch pad being equipped with for child especially, it is a kind of device of simulated touch plate, and the uncontrollability of gesture identification is become to controlled.And as supporting method with it, fast operation, recognition efficiency are high, operation has certain method for normalizing, and speed is fast.

Embodiment
Below in conjunction with accompanying drawing and embodiment, the present invention is described in further detail:
The device of this gesture identification for preschool education is comprised of PC, camera and special touch pad and height adjustable support thereof.The touch pad that this piece is special can make a transparent rigid plastic sheet, be placed in before camera above support nearby, be not connected with camera, PC, do not arrange too high (child's use), on touch pad, be carved with the multi-direction coordinate system using in the method, in initial point and the shape of palm on the intersection point place class of certain length drawn circle and axis of orientation as radius of take.We generally build up 8 direction coordinate systems coordinate system, upper, upper right, the right side, bottom right, under, lower-left, a left side, upper left submeter label be 1,2,3,4,5,6,7,8.
