Abstract

The invention discloses an image correction method and shooting equipment, and belongs to the field of projection display. According to the method, after a shot image obtained by shooting a projection screen is obtained, the shot image can be sent to laser projection equipment. Therefore, the laser projection equipment corrects the projection position of the projection image to be displayed based on the shot image, thereby ensuring the display effect of the projection image. Moreover, if the shooting equipment detects that the frame of the projection screen in the preview picture is located outside the target area of the preview picture, the adjustment prompt information can be displayed. In this way, a user can adjust the shooting parameters of the camera in time, it is ensured that the shot image collected by the camera meets the requirement, the reliability of the collected shot image is ensured, and then the reliability of correcting the projection position of the projection image to be displayed based on the shot image is improved.

Description

technical field [0001] The present disclosure relates to the field of projection display, in particular to an image correction method and a shooting device. Background technique [0002] Ultra-short-throw laser projection equipment can project and display projected images on a projection screen. For ultra-short-focus laser projection equipment, due to the principle of projection imaging, the light is emitted obliquely upwards, so the position between the laser beam emitted by the optical engine in the ultra-short-focus laser projection equipment and the projection screen must be strictly aligned. A slight shift of the focal laser projection equipment can also cause distortion or distortion of the picture. If the user accidentally moves the ultra-short-focus laser projection device, the projected image projected and displayed by the ultra-short-focus laser projection device may exceed the projection screen, resulting in a poor display effect of the displayed projected image....
