[0039] Example
[0040] Such as figure 1 As shown, this embodiment provides a method for automatically adjusting a projection image, including:
[0041] Step S1: Turn on the camera to obtain the captured projection surface area;
[0042] Step S2: Obtain the largest connected area in the projection surface area;
[0043] Step S3: Obtain the largest inscribed rectangular area within the largest connected area;
[0044] Step S4: Adjust the projection image according to the acquired largest inscribed rectangular area.
[0045] Specifically, the step of obtaining the largest connected area in the projection surface area, namely step S2, specifically includes:
[0046] Step S211: Mark the image areas of the projection surface with similar gray values as the same area according to the gray information similarity algorithm;
[0047] Step S212: Obtain all connected areas in the same area;
[0048] Step S213: Obtain the number of pixels in each connected area respectively, and determine the area wi...
