Abstract
The invention discloses an intelligent base of an Android mobile phone for video chat. The intelligent base comprises a video information acquisition module, a face detection module and a face tracking module. The base of the mobile phone disclosed by the invention can automatically identify a face image of a user and track the face image of the user in real time so that the user can use a video chat function more conveniently.
Description
Technical field
The present invention relates to a kind of Android mobile video intelligent base of chatting, belong to the mobile phone technique field.
Background technology
At present, along with the development of mobile communication technology, the cellphone subscriber increases sharply, and the Video chat function more and more comes into one's own.But because the cellphone subscriber is on the move when using mobile phone to carry out Video chat even in mobile, uses this function.If a kind of practical technique can be arranged, make mobile phone can discern user's face-image automatically, and face-image that can the real-time tracing user, will make the user feel convenient.
Summary of the invention
Technical problem to be solved by this invention is that the deficiency to prior art provides a kind of Android mobile video intelligent base of chatting.
A kind of Android mobile video intelligent base of chatting comprises: video information acquisition module, face detection module and facial tracking module;
Face detection module is used for the video information according to the acquisition of video information acquisition module, obtains Video chat person face-image through analyzing and processing;
Facial tracking module is used for according to this chat person's face-image sequence; Facial image sequence is analyzed; Calculate the two-dimensional position coordinate of face-image on every two field picture; And according to the different character value, same moving target in the different frame in the image sequence is associated, obtain the complete movement locus of each moving target; The step motor drive module is according to the tracking results of facial tracking module, and drive stepping motor is rotated, and stepping motor drives said video information acquisition module and rotates, and real-time tracking Video chat person is facial.
The described Android mobile video intelligent base of chatting, the track algorithm that said facial tracking module adopts is the Camshift algorithm.
Mobile phone base of the present invention can be discerned user's face-image automatically, and face-image that can the real-time tracing user, and the user uses the Video chat function convenient.

Fig. 1 is the Android mobile video of the present invention intelligent base theory diagram of chatting;
Fig. 2 is the workflow diagram of face detection module of the present invention.
Embodiment
Below in conjunction with specific embodiment, the present invention is elaborated.
With reference to figure 1, the Android mobile video intelligent base of chatting comprises: video information acquisition module, face detection module and facial tracking module;
Face detection module is used for the video information according to the acquisition of video information acquisition module, obtains Video chat person face-image through analyzing and processing;
Facial tracking module is according to this chat person's face-image sequence; Facial image sequence is analyzed; Calculate the two-dimensional position coordinate of face-image on every two field picture, and, same moving target in the different frame in the image sequence is associated according to the different character value; Obtain the complete movement locus of each moving target, promptly in the continuous video sequence, set up the corresponding relation of moving target.The track algorithm that adopts is Camshift algorithm (being that opencv carries target tracking algorism).The CamShift algorithm, promptly " Continuously Apative Mean-Shift " algorithm is a kind of motion tracking algorithm.It mainly reaches the purpose of tracking through the colouring information of moving object in the video image.This algorithm can resolve into three parts: Back Projection calculates, Mean Shift algorithm, CamShift algorithm.
The step motor drive module is according to the tracking results of facial tracking module, and drive stepping motor is rotated, and stepping motor drives said video information acquisition module and rotates, and real-time tracking Video chat person is facial.
With reference to figure 2; Face detection module is used at input picture face being extracted from numerous and jumbled background; And return information such as facial position, size in image; Concrete, the present invention adopts the histogram distribution situation based on gray level image to judge whether to be facial and definite facial scope.The coloured image that at first camera is returned converts gray level image into, then image is carried out histogram equalization, utilizes whether grader is that face is discerned to a certain zone in the image.(carry facial detection function among the opencv, be based on the adaboost face detection algorithm of Haar characteristic)
Should be understood that, concerning those of ordinary skills, can improve or conversion, and all these improvement and conversion all should belong to the protection range of accompanying claims of the present invention according to above-mentioned explanation.
Claims (2)
1. an Android mobile video intelligent base of chatting is characterized in that, comprising: video information acquisition module, face detection module and facial tracking module;
