Problems solved by technology
[0003] However, in actual use, due to the short-focus or ultra-short-focus projection equipment at a short distance and a large elevation angle, it is difficult for users to adjust the projection screen projected by the projection equipment on the projection screen to align with the frame of the projection screen , which affects the projection effect of the projection device
At the same time, it is complicated to adjust the projection screen to align with the frame of the projection screen by manual adjustment, and it is often impossible to obtain the projection effect that meets the user's requirements.

The present disclosure relates to a projection correction method, device, storage medium, and projection equipment. The method includes: acquiring a target image captured by an image acquisition device, determining a partial boundary of the imaging medium area according to the target image, and determining a partial boundary of the imaging medium according to the partial boundary of the imaging medium. The coordinates of each vertex of the imaging medium determine the target transformation relationship according to the display area of the projection screen, determine the target projection area according to the coordinates of each vertex of the imaging medium and the target transformation relationship, and correct the projection screen display area according to the target projection area, so that the projection screen displays area coincides with the imaging medium area. The disclosure can determine the target projection area according to the part of the boundary corresponding to the imaging medium, combined with the target transformation relationship, and use the target projection area to correct the display area of the projection screen to ensure that the projection of the projection device is aligned with the imaging medium. The operation is simple and does not require manual adjustment by the user. , the projection effect that meets the user's requirements can be obtained.
Description
technical field [0001] The present disclosure relates to the field of projection technologies, and in particular, to a projection correction method, device, storage medium, and projection equipment. Background technique [0002] With the continuous development of projection technology, short-throw or ultra-short-throw projection equipment is becoming more and more popular, and will soon become the mainstream category of home projection equipment. When using a short-focus or ultra-short-focus projection device, in order to obtain a better projection effect, the short-focus or ultra-short-focus projection device is usually used in conjunction with a projection screen, so that the projection device can project a clear image on the projection screen. image. [0003] However, in actual use, due to the short-focus or ultra-short-focus projection equipment at a short distance and a large elevation angle, it is difficult for users to adjust the projection screen projected by the pr...
