Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, technical scheme is further elaborated.
As it is shown in figure 1, the embodiment of the present invention provides a kind of projector equipment 100 to include:
Collection portion 10, for gathering human body image according to the induced signal obtained；
Test section 20, for the projection orientation of detection of projection devices 100；
Process portion 30, if for described projection orientation be vertical direction, then described human body image is carried out recognition of face and obtains person body orientation, according to described person body orientation rotate prestore image to be projected；
Projection Division 40, for image to be projected projecting to the screen specified by postrotational.
The present invention is by gathering the projection orientation of human body image and detection of projection devices 100, if described projection orientation is vertical direction, described human body image is carried out recognition of face and obtains person body orientation, according to described person body orientation revolved projection picture, thus make the projected picture can automatically according to the use orientation adjustment of user, property greatly convenient for users to use.
As preferably, also including: induction part 50, for when human body is with projector equipment 100 predeterminable range scope apart, producing an induced signal.
As a kind of optimal way of described induction part 50, described induction part 50 has for sending ultrared thermal infrared human inductor at induction region internal induction human body.When human body is near projector equipment, human inductor utilizes thermal infrared principle to detect that human body is close, projector equipment detected human body near time export projected picture again, time human body leaves close projected picture, play save electricity and extend projection bulb service life.
As a kind of optimal way in described collection portion 10, described collection portion 10 has for obtaining the picture pick-up device of human body image information in described induction region；Preferably, described picture pick-up device captures human body image data with the speed of 25 frames per second.
As preferably, described test section 20 has the two axle gravity sensors that the acceleration of gravity of the projection lens using projector equipment 100 detects as described projection orientation.
As it is preferred that, when the x-axis gravity acceleration value of described two axle gravity sensors detections is normal acceleration of gravity and y-axis gravity acceleration value is 0, described projection orientation is horizontal direction；When the x-axis gravity acceleration value of described two axle gravity sensor detections is 0 and y-axis gravity acceleration value is normal acceleration of gravity, described projection orientation is vertical direction, wherein, with level orientation for y-axis, to be perpendicular to y-axis for x-axis.May determine that projection orientation is level or vertical orientations accordingly.When projection orientation is in level orientation, projected picture does not need to rotate, and when projection orientation is in vertical orientations, projected picture needs to rotate, and the picture that otherwise user sees is to stand upside down.
Described human body image is carried out recognition of face and obtains a kind of optimal way of person body orientation by described process portion 30, picture pick-up device is captured human body image data with the speed of 25 frames per second, carry out recognition of face detection calculations, by image convergent-divergent successively in proportion, the subwindow of the 20*20 of picture after scaling compares with human-face detector successively, differentiation is face or non-face, then the extraction of face local features is carried out, judge through grader, detect that face is front face or side face, front face represents user at projector equipment 100 dead ahead, left side face represents the user right side side at projector equipment 100, right side face represents the user left side side at projector equipment 100.After judging that user is made in the dead ahead of projector equipment 100 or left side side or right side side, carry out the rotation of picture further according to the person body orientation of user.
As it is preferred that, as in figure 2 it is shown, when described process portion 30 is dead ahead according to described person body orientation, to described rotation turnback image to be projected.
As it is preferred that, as it is shown on figure 3, when described process portion 30 is left side side according to described person body orientation, to described image to be projected according to being rotated clockwise 90 degree.
As it is preferred that, as shown in Figure 4, when described process portion 30 is right side side according to described person body orientation, to image to be projected according to being rotated clockwise 270 degree.
As further preferred, if as it is shown in figure 5, it is horizontal direction that described process portion 30 is additionally operable to described projection orientation, then not revolving described image to be projected；When being horizontal direction due to projection orientation, it is front projection relative to user, so need not rotate image to be projected.
The projection lens of projector equipment of the present invention is made can freely movable and stretchable out and bending 90 degree; it is achieved thereby that projected picture can not only be able to be projected to above wall or curtain; can also be without needing to project to above desktop by external force; can allow user that this projector equipment is used as panel computer; projector equipment is reflection light, compares general panel computer and can relatively protect the vision of user.Time above projector equipment stretching also 90 degree of projected pictures of bending to desktop, it is possible to achieve automatically adjust projected picture direction automatically according to the actually used device of user.
In sum, the present invention is by gathering the projection orientation of human body image and detection of projection devices, if described projection orientation is vertical direction, described human body image is carried out recognition of face and obtains person body orientation, according to described person body orientation revolved projection picture, thus make the projected picture can automatically according to the use orientation adjustment of user, property greatly convenient for users to use.It addition, adopt thermal infrared human inductor, at human body sensing to just projecting afterwards, it does not have do not project during user, save electricity, and protect the service life of projector equipment.
Last it is noted that above example is only in order to illustrate technical scheme, it is not intended to limit；Although the present invention being described in detail with reference to previous embodiment, it will be understood by those within the art that: the technical scheme described in foregoing embodiments still can be modified by it, or wherein portion of techniques feature is carried out equivalent replacement；And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of various embodiments of the present invention technical scheme.
