For the first projection touch module 13, the following four situations are generally available:

The first case:

The first projection touch module 13 can include: a visible light camera, an infrared light camera, an infrared light source, and a first processing chip. Wherein, the infrared light source emits infrared light to cover the area where the projection image is located; the infrared camera determines the distance between the touch object and the projected image by the size of the reflected light spot of the infrared light; the visible light camera can capture the projected image to obtain a visible light image; The processing chip can obtain the three-dimensional image through the image processing algorithm according to the touch data (the distance between the touch object and the projected image and the visible light image), thereby obtaining the touch position of the touch object, and sending the touch position to the first The main processing module 11 can determine the operation instruction of the user according to the touch position, such as clicking, double-clicking, sliding or invalid operation instruction, etc., and then performing operation processing on the projection screen according to the operation instruction.

Wherein, the infrared laser diode projects the infrared laser grid to the area where the projection image is located, and the reflective infrared laser receiver receives the reflected laser light of the infrared laser grid to determine the intensity of the reflected laser; that is, the touch data, and the fourth processing chip according to the reflected laser The intensity determines the touch position of the touch object on the projected image.

The ultrasonic signal transmitter transmits an ultrasonic signal to an area where the projection picture is located; the ultrasonic signal receiver receives the reflected ultrasonic signal; and the processing chip in the first projection touch module 13 can receive the reflected ultrasonic signal according to the time of transmitting the ultrasonic signal. The time sequence determines the propagation time of the ultrasonic signal, thereby determining the distance Z between the touch object and the projected picture and transmitting it to the first main processing module 11.

The first projection touch module 13 may also include a TOF (Time of Flight) sensor. The TOF sensor emits modulated near-infrared light and is reflected by the touch object. The first projection touch module 13 The processing chip calculates the distance Z between the touch object and the projected picture by calculating the near-infrared light emission and reflection time difference or phase difference, and sends the distance Z to the first main processing module 11.

As an implementation manner of the embodiment of the present invention, the first main processing module 101 is further configured to: before the projection module 102 performs projection, detect whether the bracket device 200 is connected, and then perform a series of function settings.

Specifically, when the bracket device 200 is not detected, the form of the projection screen is set to a first preset form, and the power consumption of the projection device 100 is controlled within a preset range, and the brightness and the working frequency of the projection screen are controlled to be less than a preset value. . Since the bracket device 200 is not connected, the projection device 100 is generally used as a wearable projection device, for example, on a wrist of a human body, and projected onto the back of the hand, and the user himself or herself views the general projection distance and viewing distance. At this time, the first main processing module 101 can set the form of the projected picture to a first preset form more suitable for close-range projection and viewing, and at the same time, in order to save power as much as possible because the bracket device 200 does not supply power to the projection device 100. The brightness and working frequency of the projected picture can be appropriately limited to be smaller than the preset value.

When the cradle device 200 is detected, the form of the projection screen is set to a second preset form. At this time, the projection device 100 is generally placed on the bracket device 200 to project to a wall surface, a desktop, a ceiling, etc., and the projection distance is relatively far. It may be that many people view the projection image together, then the first main processing module 101 at this time The form of the projected picture can be set to a second preset form more suitable for long-distance projection and viewing. Meanwhile, since the stand device 200 can supply power to the projection device 100, the power is sufficient, so the brightness and operating frequency of the projected picture can be not limited. .

The specific determination manner may be any existing manner, for example, a time-of-flight algorithm may be used, and no specific description is provided herein.

Correspondingly, the first main processing module 101 is further configured to: determine whether the projection distance determined by the second projection touch module 202 is less than a preset distance.

Specifically, when the projection distance is less than the preset distance, it indicates that the projection distance is relatively close at this time, and it is likely that the user wears the projection device 100 to a predetermined part of the body for projection, for example, the projection device 100 is worn on the wrist. Projection on the back of the hand, at this time, the back of the hand will be slightly raised for convenient viewing. The angle between the projection direction and the plane of the back of the hand is generally about 45 degrees, then the first preset keystone angle is The number can be a trapezoidal correction angle parameter corresponding to the angle. The first preset trapezoidal correction angle parameter can be set by a person skilled in the art according to the position that the projection device 100 can actually be worn on the human body, which is not specifically limited herein.

When the projection distance is not less than the preset distance, it indicates that the projection distance is relatively close at this time, and it is likely that the user places the projection device 100 at a certain position to project to a distant wall or the like. In this case, the horizontal projection is generally performed. The angle between the projection direction and the plane of the projection screen is generally 90 degrees, and then the second preset trapezoidal correction angle parameter may be a trapezoidal correction angle parameter corresponding to the angle, and the second preset trapezoidal correction angle parameter may be determined by the prior art. The person is set according to the actual possible projection direction of the projection device 100, and is not specifically limited herein.

After the first main processing module 101 sets the current trapezoidal correction angle parameter to the first preset trapezoidal correction angle parameter or the second preset trapezoidal correction angle parameter, the first preset trapezoidal correction angle parameter or the second pre-preparation The trapezoidal correction angle parameter is sent to the projection module 102, and the projection module 102 can perform projection according to the received first preset trapezoidal correction angle parameter or the second preset trapezoidal correction angle parameter to ensure the quality of the projected image and minimize Small picture distortion.

As an implementation manner of the embodiment of the present invention, the first main processing module 101 is further configured to: when the rack device 200 is detected, determine a rotation angle of the projection device 100, thereby determining a current trapezoidal correction angle parameter.

The device 100 is rotated downward by 45 degrees to a position such as a table top, a floor, or the like (such as the table throw mode shown in FIG. 6), and the projection apparatus 100 is rotated upward by 60 degrees to a position such as a ceiling (such as the head-up mode shown in FIG. 7). For convenience of operation, three different trapezoidal correction angle parameters, that is, a third preset trapezoidal correction angle parameter, a fourth preset trapezoidal correction angle parameter, and a fifth preset trapezoidal correction angle parameter may be preset in advance corresponding to the three projection modes. . The correspondence between the reference numerals and the components in FIG. 5 to FIG. 7 is: the projection device 100, the projection module 102, the cradle device 200, the second projection touch module 202, and the plane 300 on which the projection screen is located.

Among them, in the projection mode projection process shown in FIG. 7, since the position of the projection screen is generally high, it is inconvenient for the user to directly touch the projection screen. At this time, the projection device 100 can establish a connection with the smart phone through the bracket device connection module 103, and further, the user can control the projection screen through the special software installed on the smart phone, which is very convenient.

In a practical application, the first main processing module 101 can determine the rotation angle of the projection device 100 by using an internal acceleration sensor or the like. When the rotation angle is determined to be 0 degrees, the current trapezoidal correction angle parameter can be set to the third preset trapezoidal correction angle. parameter. When it is determined that the rotation angle is 45 degrees, the current trapezoidal correction angle parameter is set as the fourth preset trapezoidal correction angle parameter. When it is determined that the rotation angle is 60 degrees, the current trapezoidal correction angle parameter is set as the fifth preset trapezoidal correction angle parameter. After the current trapezoidal correction angle parameter is set, the set trapezoidal correction angle parameter is sent to the projection module 102, and the projection module 102 can perform projection according to the set trapezoidal correction angle parameter to ensure the quality of the projected picture and minimize the picture. distortion.

The angle of the plane is set, the current trapezoidal correction angle parameter is set according to the angle, and the current trapezoidal correction angle parameter is sent to the projection module 102, so that the projection module 102 performs projection according to the current trapezoidal correction angle parameter.

Specifically, the first main processing module 101 can obtain an angle between the projection direction and the plane of the projection screen in any existing manner, for example, can be projected by the camera mounted on the projection device 100 or the rack device 200 and the projection module 102.
