Wherein changing the secondary projection image projected toward the secondary projection region includes switching the secondary projection image, inserting the primary projection image in the secondary projection region, displaying the primary projection image in a localized area of the secondary projection image, and the like.
For example: the plurality of options may be configured to include a first option, and when the first option is clicked, the control system controls the optical-mechanical system to project a sub-projection image to the sub-projection area, where the sub-projection image is identical to the main projection image, and the sub-projection image is located in a local area of the sub-projection image, so as to achieve a "picture-in-picture" effect.
The plurality of options can be set to comprise a second option, and when the second option is clicked, the control system controls the optical-mechanical system to switch the image projected by the secondary projection area to be a main projection image, so that the inter cut is realized.
Of course, changing the sub-projection image projected onto the sub-projection area is not limited to the above-described forms, and is not listed here.
In the practical application process, the main projection area is a close-range projection area, and the distance from the teacher or the instructor is close, so that the teacher or the instructor can change the secondary projection image of the secondary projection area through the main projection area. The secondary projection area is a remote projection area facing the student or listener so that the student or listener can view the secondary projection image.
Further, in order to improve the flexibility of the apparatus, the projector is configured to include two main projection areas located in the same plane, and main projection images of the two main projection areas are identical. The projector comprises a projector body 100, wherein the two main projection areas are respectively positioned on two opposite sides of the projector body 100, namely, two close-range projection areas are arranged on two opposite sides of the projector, so that a user can flexibly select the projector according to actual conditions.
The optical-mechanical system includes two main lenses 12, the two main lenses 12 are respectively disposed on the two opposite sides of the projector body, and the main lenses 12 are used for projecting a main projection image to a main projection area located on the same side of the projector body.
The simultaneous provision of the same image to the two primary lenses 12 may be achieved in particular by a spectroscopic system or two optical-mechanical systems, the particular implementation principle of which will be described below.
In this embodiment, in order to achieve the purpose that a teacher or an interpreter can flexibly control the projected image, the setting of the projector further includes:
two laser scanning arrays 7 respectively provided on the opposite sides of the projector body 100;
two first cameras 8 respectively provided on the opposite sides of the projector body 100;
the laser scanning array 7 is used for emitting a plurality of laser lines covering the surface of the main projection area positioned on the same side of the projector body 100; the first camera 8 is configured to obtain laser reflected when a user touches a surface of a main projection area located on the same side of the projector body 100;
the control system is connected with the first camera 8, and is further configured to determine a position touched by a user according to the laser acquired by the first camera 8, and control the optical-mechanical system to project a main projection image corresponding to the touched position to the main projection area.
Specifically, the laser scanning array 7 may be disposed at the bottom of the projector body 100 of the projector, which is close to the plane in which the main projection area is located.
According to the technical scheme, the laser scanning array 7 is utilized, so that the accuracy of touch position detection can be improved, meanwhile, under the condition that a plurality of laser heads (such as 3-5) irradiate a main projection area at multiple angles, the detection of the multi-point touch position can be realized, teachers or explanation persons can respond timely, and corresponding operations are executed.
The laser scanning array 7 usually adopts an infrared line of 850nm or 808nm, and a sector which cannot be seen by naked eyes is formed, so that the whole main projection area is covered. The thickness of the laser infrared sector is approximately between 1 and 2mm, and objects such as fingers or special stylus pen are close to the main projection area, the infrared rays on the laser infrared sector are reflected to form reflection points, and the tip of the fingers or the stylus pen can be displayed as an infrared point. The first camera 8 captures the infrared reflection point, and transmits the main projection image of the main projection area to the control system 1, the control system 1 processes and analyzes the main projection image, recognizes the touch event and the coordinate position of the infrared reflection point, realizes the control of various application icons in the main projection image, and then invokes corresponding control instructions to execute corresponding operations, such as: a new main projection image is formed and then projected to the main projection area through the main lens 12.

The control system 1 is connected with the second camera 10, and is used for determining the position of the laser, controlling and realizing the control of various application icons in the main projection graph, and executing corresponding operations.

The laser point hitting the main projection area is captured by the second camera 10, and the main projection image of the main projection area is transmitted to the control system 1, the control system 1 processes and analyzes the main projection image, recognizes the touch event and the coordinate position of the laser point, and then invokes corresponding control instructions to realize the control of various application icons in the main projection image, including multi-point touch control, so as to achieve the projection control effect of 'what is hit'.
The second camera 10 and the first camera 8 can be the same camera, and under the condition that the laser scanning array 7 does not work, the second camera 10 captures laser points emitted by the laser pen, so that the flexibility of the device is improved.
The laser spot or the laser reflection point captured by the camera can be fixed in position, or can be in actions such as single click, double click or scribing. When the distance or inclination of the main projection area where the laser spot or the laser reflection point is located is changed, trapezoidal correction is necessary, otherwise, coordinate calculation may be inaccurate. Coordinate calculation compensation is sometimes required in real time according to the change of the projection area: the first step, performing trapezoidal correction on the length and width directions of a projection area where a laser spot or a laser reflection spot is located respectively; secondly, recognizing and calculating coordinates of the laser point or the laser reflection point; and thirdly, performing association calculation on the coordinates of the laser point or the laser reflection point and the trapezoid correction parameters to obtain a real-time compensation value.

At this time, only the focusing of the lens is required to be ensured.
