Abstract
The invention relates to an interface control method based on regional movement detection. The interface control method comprises the following steps of: acquiring video information of a user by a camera; showing an icon of a control command on the interface of a current video window after the movement intensity in the video information is detected to reach a set first threshold value, pre-processing the icon and calculating a three-frame-difference image; judging the movement information in the icon region according to the number of pixels in the three-frame-difference image; and judging whether to operate the control command corresponding to the icon according to the condition whether the accumulation intensity of the movement information reaches a second threshold value. The interface control method based on regional movement detection disclosed by the invention is adopted, so that various application interfaces can be operated through gestures; moreover, the internal algorithm is simple and feasible without complex hardware, so that man-machine interaction convenience and easiness are effectively improved.
Description
Technical field
The present invention relates to the method for electronic product interface control, be based on concretely the interface control method that regional movement detects.
Background technology
Man-machine interaction refers between people and computing machine or other terminal device to use certain conversational language, take certain interactive mode as finishing the people that sets the tasks and the information exchanging process between the terminal.
The human-computer interaction function of terminal system is a key factor of decision systems " friendliness ".But human-computer interaction function is mainly realized by external unit and the corresponding software of input and output.Can mainly contain for the equipment of man-machine interaction keyboard demonstration, mouse, telepilot, various pattern recognition apparatus etc.With the corresponding software of these equipment be exactly the part that operating system provides human-computer interaction function.The Main Function of man-machine interaction part is operation and the understanding of control relevant devices, and carries out relevant various command and the requirement of transmitting by the human-computer interaction device.Mostly early stage man-machine interaction facility is keyboard display.The operator is by the keyboard input command, and operating system is received and carried out after the order and the result is shown by display.The order of input can have different modes, but the explanation of each bar order is clear, unique.
Along with the development of computer technology, operational order is also more and more, and function is also more and more stronger.Along with pattern-recognition, such as the development of the input equipments such as speech recognition, Chinese Character Recognition, action recognition, gesture identification, user and device end are by becoming alternately possibility on similar natural language or this one-level of restricted natural language.In addition, carry out the direction that man-machine interaction also is research by figure.These man-machine interactions can be described as intelligentized man-machine interaction.
Summary of the invention
The invention provides a kind of interface control method that detects based on regional movement, be used for operating using the interface by gesture, the method simple possible does not need complicated hardware, improves the conveniency of man-machine interaction.
The present invention is based on the interface control method that regional movement detects, obtain user's video information by camera, after exercise intensity in detecting video information reaches the first threshold of setting, express the icon of steering order at the interface of current video window, described icon is carried out pre-service and calculates three frame difference images; Judge movable information in the described icon area by calculating number of pixels in three frame difference images, whether reach Second Threshold according to the intensity of described movable information accumulation and judge whether to move the corresponding steering order of icon.In Application Program Interface the icon of expression steering order can be upwards, downwards, left, to the right, cancellation, determine etc.; The icon of expression steering order can be in player interface: broadcast, time-out, F.F., rewind down, upper one, next etc.Wherein choosing of first threshold and Second Threshold is in the actual moving process of program, in real time the strength information of image gathered, and in conjunction with best image information intensity, the Measurement and Computation that carries out is repeatedly chosen, this threshold value of choosing mode and finally obtaining can either be user-friendly, can get rid of again the interference of maloperation.
Wherein said three frame difference images are a kind of method for testing motion commonly used during image is processed, and its concrete calculation procedure comprises:
A. described icon area is obtained three continuous two field pictures;
Three two field pictures that b. will obtain are converted into gray level image;
C. with two adjacent width of cloth image subtractions, obtain error image;
D. get the larger point of pixel value that the c step obtains pixel in two width of cloth error images and form three frame difference images.
Preferably, described camera is the 2D camera, uses common 2D camera can effectively reduce cost.
After tested, the interface control method that detects based on regional movement of the present invention can operate various application interfaces by gesture, and inner algorithm simple possible, does not need complicated hardware, effectively raises the conveniency of man-machine interaction.
Below in conjunction with the embodiment of embodiment, foregoing of the present invention is described in further detail again.But this should be interpreted as that the scope of the above-mentioned theme of the present invention only limits to following example.Do not breaking away from the above-mentioned technological thought situation of the present invention, various replacements or change according to ordinary skill knowledge and customary means are made all should comprise within the scope of the invention.
Embodiment
The present invention is based on the interface control method that regional movement detects, obtain user's video information by common 2D camera, after exercise intensity in detecting video information reaches the first threshold of setting, express the icon of steering order at the interface of current video window, described icon is carried out pre-service and calculates three frame difference images; Such as the icon of expression steering order in Application Program Interface can be upwards, downwards, left, to the right, cancellation, determine etc.; The icon of expression steering order can be in player interface: broadcast, time-out, F.F., rewind down, upper one, next etc.Judge movable information in the described icon area by calculating number of pixels in three frame difference images, whether reach Second Threshold according to the intensity of described movable information accumulation and judge whether to move the corresponding steering order of icon.Choosing of first threshold and Second Threshold is in the actual moving process of program, in real time the strength information of image gathered, and in conjunction with best image information intensity, the Measurement and Computation that carries out repeatedly chosen.
Wherein said three frame difference images are a kind of method for testing motion commonly used during image is processed, and its concrete calculation procedure comprises:
A. described icon area is obtained three continuous two field pictures;
Three two field pictures that b. will obtain are converted into gray level image;
C. with two adjacent width of cloth image subtractions, obtain error image;
D. get the larger point of pixel value that the c step obtains pixel in two width of cloth error images and form three frame difference images.
By the interface control method that detects based on regional movement of the present invention, can operate various application interfaces by gesture, and inner algorithm simple possible, do not need complicated hardware, effectively raise the conveniency of man-machine interaction.
