The invention discloses an automatic laser focus and definition compensation method, device, projection equipment and computer storage medium. The automatic laser focus and clarity compensation method determines the automatic laser focus distance according to the projection picture currently output by the projection device; determines the projection lens distance of the projection device according to the automatic laser focus distance and the preset picture clarity compensation data Adjustment parameters, wherein the image clarity compensation data is obtained through training and calculation based on a preset user portrait model; according to the adjustment parameters, the position of the projection lens is adjusted so that the projection image can be accurately focused. Compared with the traditional trapezoidal correction method, the present invention not only realizes the automatic adjustment of the focus of the projection screen, which is convenient for users to use the projection equipment, but also flexibly adjusts the parameters used for the focus of the projection screen based on the user's personal usage habits, and improves the projection quality. The accuracy and intelligence of picture focusing.
Description
technical field [0001] The present invention relates to the field of projection technology, in particular to an automatic laser focusing and clarity compensation method, device, projection equipment and computer-readable storage medium. Background technique [0002] With the development of computer technology, projection equipment has become more and more widely used in people's daily work or life. In order to ensure the clarity of the projected picture, it is necessary to make the projection lens on the projector that outputs the projected picture be in a position that can accurately focus the projected picture so as to maintain high definition. [0003] Since the projection device will inevitably change its position during daily use, it is usually necessary to repeatedly adjust the position of the projection lens on the projector in order to focus the projected image to obtain a higher definition. However, the existing adjustments for the projector lens are mostly based o...
