if the X1 and the X2 are not equal, the judgment is unqualified, the controller (160) sends a control model to the linear displacement mechanism (500), the first motion assembly (502) provides power to the linear position mechanism up-and-down motion module (501), the stereoscopic projection device (100) is made to move up and down, and finally the X1 and the X2 are equal, and the image of the light path in the middle is judged to be located in the middle of the screen.
Preferably, the method further comprises adjusting the front and back inclination angle of the stereoscopic projection device (100) in the horizontal direction, and the adjusting process is as follows:
firstly, image light of a middle light path is closed, a shading device (102) of a liquid crystal box of the middle light path is closed, and meanwhile, an upper reflected light beam and a lower reflected light beam are projected on a screen, wherein the image light of the upper reflected light beam is the upper half part of a Chinese character 'tian', the upper edge line is marked as 305, the image light of the lower reflected light beam is the lower half part of the Chinese character 'tian', and the lower edge line is marked as 306;
the controller (160) calculates 301 the distance between the upper edge line and 305 of the screen to be X3, and the distance between the lower edge line and 306 of the screen to be X4, if the distance between the X3 and the X4 is not equal, the controller judges that the screen is not qualified, and sends a control model to the angle adjusting mechanism (600), and the controller provides power to the angle adjusting sliding table (601) by the second motion assembly until the distance is adjusted to be equal to X3 and X4.
Preferably, the projector needs to project a field image to the screen, and simultaneously lets the upper and lower reflected light beams not project on the screen, only shows middle projected light beam, specifically includes:
and closing the upper light path liquid crystal box shading device (101) and the lower light path liquid crystal box shading device (103) to ensure that the upper and lower reflected light beams cannot be projected out through the stereoscopic projection device (100).
Preferably, the camera needs to project a field image to the screen, and simultaneously lets the upper and lower reflected beams not project on the screen, only displays the middle projected beam, and specifically includes:
adjusting the tilt angles of the upper optical path reflector (131) and the lower optical path reflector (132) to cause the upper optical path reflector (131) to rotate upwards to an extreme position, so that the reflected image of the upper optical path moves horizontally upwards to the uppermost position and moves to a position where no part is overlapped with the image of the middle optical path;
simultaneously the lower optical path reflector (132) is rotated downwardly to an extreme position such that the reflected image of the lower optical path moves downwardly to a lowermost position at which no portion of the reflected image of the lower optical path coincides with the middle optical path.
Example four:
the implementation process specifically comprises the following steps:
the stereoscopic projection device (100) is placed in front of the projector (200), and light projected by the projector (200) is projected on the screen.
The method comprises the steps of firstly determining the position of a screen, selecting an upper edge line and a lower edge line of the screen as reference bases, projecting pure white light by a projector to illuminate the screen, shooting the screen by the projector after the screen is illuminated, and calibrating the upper edge line and the lower edge line of the screen as the reference bases in a shot screen image. The upper edge line of the screen is labeled 301 and the lower edge line is labeled 302 in fig. 3.
The camera then needs to project a field image onto the screen while leaving the upper and lower reflected beams not projected onto the screen, showing only the middle projected beam, the upper edge of the field of the middle projected beam being marked 303 and the lower edge being marked 304, see fig. 4. The reason why the upper and lower reflected light beams are not projected on the screen is that in the initial state of the stereo projection device (100), the middle light path displays an integral image projected by the projector, the upper reflected light beam is the upper half part of a projection picture of the projector, the lower reflected light beam is the lower half part of the projection picture of the projector, the upper reflected light beam is not necessarily coincided with the upper half part of the middle light path, the lower reflected light beam is not necessarily coincided with the lower half part of the middle light path, the image has double images, judgment is affected, and therefore the upper and lower reflected light beams are required to be not projected on the screen. Two methods are introduced in this patent to prevent the upper and lower reflected beams from being projected on the screen. The first kind of device closes the upper light path liquid crystal box light shading device (101) and the lower light path liquid crystal box light shading device (103), so that the upper and lower reflected light beams cannot be projected through the stereo projection device (100). The second method is as follows: the upper and lower tilt angles of the upper optical path reflector (131) and the lower optical path reflector (132) are adjusted so that the upper optical path reflector (131) is rotated upward to an extreme position so that the reflected image of the upper optical path will be horizontally moved upward to an uppermost position and moved so that no portion coincides with the image of the middle optical path. Simultaneously the lower optical path reflector (132) is rotated downwardly to an extreme position such that the reflected image of the lower optical path moves downwardly to a lowermost position where no portion of the reflected image of the lower optical path coincides with the middle optical path, see fig. 5.
The camera (112) shoots an image on the screen, the image information is sent to the controller (160), and the controller (160) judges whether the field character cursor is positioned at the center position of the screen through an image recognition algorithm so as to judge whether the projection position is qualified. The method for judging the position of the image on the screen comprises the following steps:
in the foregoing adjustment process, an upper edge line 301 and a lower edge line 302 of the screen, and an upper edge line 303 and a lower edge line 304 of the image shaped like a Chinese character 'tian' are recorded, a distance between the upper edge line of the image recognition algorithm 301 and the upper edge line 303 is X1, and a distance between the lower edge line 302 and the lower edge line 304 is X2. If the X1 and the X2 are not equal, the judgment is unqualified, the controller (160) sends a control model to the linear displacement mechanism (500), the first motion assembly (502) provides power to the linear position mechanism up-and-down motion module (501), the stereoscopic projection device (100) is made to move up and down, and finally the X1 and the X2 are equal, and the image of the light path in the middle is judged to be located in the middle of the screen.
The image projected by the projector may not be uniformly projected onto the upper optical path reflector (131) and the lower optical path reflector (132) due to the phenomenon that the image of the upper half part and the image of the lower half part of the projector are not uniformly projected onto the upper optical path reflector (131) and the lower optical path reflector (132), which may cause the image of the lower half part of the projector to be projected onto the upper optical path reflector (131) (or the image of the upper half part of the projector to be projected onto the lower optical path reflector (132)) to be disordered. At this time, the front and back inclination angles of the stereoscopic projection device (100) in the horizontal direction need to be adjusted, and the adjusting process is as follows: the image light of the middle light path is firstly closed, the shading device (102) of the liquid crystal box of the middle light path is closed, and meanwhile, the upper reflected light beam and the lower reflected light beam are projected on a screen, the image light of the upper reflected light beam is the upper half part of the shape of the Chinese character tian, the upper edge line is marked as 305, the image light of the lower reflected light beam is the lower half part of the shape of the Chinese character tian, and the lower edge line is marked. The controller (160) calculates 301 the distance between the upper edge line and 305 of the screen to be X3, and the distance between the lower edge line and 306 of the screen to be X4, if the distance between the X3 and the X4 is not equal, the controller judges that the screen is not qualified, and sends a control model to the angle adjusting mechanism (600), and the controller provides power to the angle adjusting sliding table (601) by the second motion assembly until the distance is adjusted to be equal to X3 and X4. See FIG. 6
