As shown in Figure 1, an embodiment of the present invention provides a method for controlling a projection device, including the following steps:

Step S101 , framing a user-preset projection area to obtain a framing image.

In this step, the user downloads the automatic matching application program released by the projection equipment manufacturer, and installs the above-mentioned automatic matching application program on the user terminal. In this embodiment, the above-mentioned user terminal is preferably a mobile phone, and the above-mentioned mobile phone and projection equipment can be Connect via Bluetooth or Wi-Fi. Start the automatic matching application, the application automatically calls and turns on the camera, and displays the matching area on the screen. The user holds the mobile phone to view the projection background through the mobile phone camera. When the matching area displayed on the above screen is the area that the user expects to project, the viewfinder image is obtained while keeping the handheld position unchanged.

Wherein, when framing the user-preset projection area, the above-mentioned application program can provide a horizontal indicator and a prompt box of the framing area, so that the user can project the user-preset projection area, such as a suitable area such as a wall or a projection screen. .

Step S102, judging whether the viewfinder image includes a projected picture of the projection device.

In this step, it is determined whether the projection image of the projection device is included in the viewfinder image according to whether part of the projection image of the projection device falls into the viewfinder image. If the judgment result is yes, execute step S103.

Step S103. Obtain calibration parameters according to the position of the projection screen of the projection device in the viewfinder image.

In this step, the terminal application program detects the position, angle, and shape deviation between the projection screen of the projection device and the viewfinder image, and calculates and obtains the calibration parameters.

Step S104, sending the calibration parameters to the projection device, where the calibration parameters are used to calibrate projection parameters of the projection device.

In this step, the terminal sends the above-mentioned calibration parameters to the above-mentioned projection device through Bluetooth or wireless local area network, wherein the above-mentioned calibration parameters are used to calibrate the projection parameters of the projection device. In this embodiment, the above-mentioned projection parameters include the focal length of the projection device , lens rotation and automatic keystone calibration and other parameters.

For example, the projection screen is displayed in the lower right corner of the viewfinder image of the terminal, and when other areas are out of bounds, the terminal sends calibration parameters including right adjustment and downward adjustment to the projection device. According to the received calibration parameters, the projection device performs displacement and zoom processing of the projection lens, and performs right adjustment processing until the terminal application matches the right boundary of the projection screen and the right boundary of the viewfinder image, and feedbacks that the right boundary matches successfully. After the right adjustment process is completed, the projection device continues to perform the downward adjustment process until the terminal application matches the lower boundary of the projection screen and the lower boundary of the viewfinder image, and feedbacks that the lower boundary matching is successful, and then stops the adjustment. In the process of right adjustment and down adjustment of the above-mentioned projection equipment, it can be gradually adjusted in place through the method of micro-level, or it can be adjusted through a larger level of span adjustment and then crossed the boundary, and then adjusted by halving and shrinking.

In this embodiment, according to the calibration parameters sent by the terminal, the projection device performs a first-round automatic adjustment by gradually adjusting its position and size respectively. After the first round of adjustment is completed, the adjustment end signal is transmitted to the terminal through the wireless local area network or Bluetooth. The terminal program performs matching again, calculates and adjusts and sends the calibration parameters to the projection device for the second time. The projection device is adjusted again according to the calibration parameters sent for the second time. The above steps are repeated several times until the terminal program confirms that the projection screen is consistent with the projection area preset by the user, that is, the automatic matching of the projection screen and the projection area preset by the user is completed.

Preferably, in this embodiment, the above calibration parameters may also include anti-shake parameters. During the actual operation, the handheld terminal device will have some non-technical slight jitter, which will cause jitter deviation in the projection area preset by the user. In order to eliminate this non-technical jitter deviation, you can add anti- shake parameters. In this way, the user only needs to maintain the basic static balance when maintaining the framing image.

In this embodiment, when the user wants to move the position or adjust the size of the projection area, the user can hold the terminal and observe the content of the viewfinder to adjust the direction of the viewfinder screen after performing framing matching on the projected area preset by the user. Move to change the viewfinder image to a new round of preset projection area. The projection device re-adjusts the position of the projection screen according to the effect of the user's viewfinder screen movement, and the terminal program cooperates to complete the following matching process and complete the user's free setting of the projection area position.

In this embodiment, the projection area can also be reduced and enlarged, and the viewfinder image can be zoomed in and out on the terminal screen after framing matching is performed on the projection area by starting the terminal application program. The projection device re-adjusts the size of the projection screen according to the zoomed effect of the user's framing screen, and the terminal program cooperates to complete the matching process and complete the user's free setting of the projection area size.
