Summary of the invention
Inventor finds realizing in process of the present invention: in order to gather the operation of user in projection plane, need mobile terminal to possess image capture module, described image capture module is pointed the operation on projection plane for gathering user simultaneously.Inventor finds, in the time that described image capture module is common camera, and in obtaining user's finger-image, the image of the content of also having obtained projection module projection on finger, this can cause very large interference to correctly identifying user's finger.Interference for fear of projection content to finger identification, can adopt infrared camera to gather user's finger-image as image capture module, and an infrared light supply projection Infrared is additionally set on infrared camera side simultaneously.Because the light of projection module projection is visible ray, and infrared camera is only to infrared light sensitization, therefore only can identify the image of the finger that has reflected infrared light, and can not be subject to the impact of project content.But in this method, due to the position that infrared camera only can obtain finger manipulation, can not obtain project content, therefore cannot determine that user points corresponding project content, also cannot on terminal interface, make response.In addition,, because there is spacing projection module and infrared camera, the position of infrared light supply in terminal, can cause the center of view field of projection module and the center in the gesture identification region of infrared camera not to overlap.Like this, just can bring a complicated problem,, on the projection plane of different distance, the position in view field and gesture identification region relatively moves, and cannot obtain the view field that user's gesture operation is corresponding by static position calculation.
In order to address this problem, a kind of possible implementation is: in the time of each use projection module projection, need user to carry out manual calibration one time.Projecting a picture by projection module guides user to click successively four summits of view field, make infrared camera can locate the position at current view field place, and then the relative position relation in definite view field and gesture identification region, calculate the finger that can obtain user in the position of view field corresponding to the position in gesture identification region by respective function like this, obtained user's Cao Zuoquyu object.
But inventor's discovery, also there is defect in said method: on the one hand, when each projection, need user to carry out manual calibration, complex operation, user experiences poor; On the other hand, after user's calibration, if change has occurred projector distance, respective function also can lose efficacy, thereby causes accuracy of identification to decline, and need to recalibrate.
In sum, because the relative position in the projected area of projection module and the gesture identification region of image capture module is fixing, therefore cannot determine the position of view field easily and cause gesture identification precision not high.
