Embodiment Construction

[0052] In order to make the objectives, technical solutions and advantages of the present disclosure clearer, the embodiments of the present disclosure will be further described in detail below with reference to the accompanying drawings.

[0053] figure 1 It is a flowchart of a method for correcting a projected image provided by an embodiment of the present disclosure. The correction method can be applied to laser projection equipment. like figure 1As shown, the method can include:

[0054] Step 101, in response to the correction instruction, project and display the corrected image on the projection screen.

[0055] refer to figure 2 , the laser projection device 10 can project and display the corrected image on the projection screen 20 . Wherein, the corrected image may be an image pre-stored in the laser projection device, and the corrected image may include a plurality of mark graphics. Both the corrected image and the projection screen may be polygons, eg, rectangl...

Abstract

The invention discloses a projected image correction method and laser projection equipment, and belongs to the field of projection display. The laser projection device can determine the target projection position of the marked graph on the projection screen according to the perspective transformation matrix and the first shooting position of each marked graph in the shot image. Afterwards, the laser projection device can correct the projection position of the projection image according to the target projection position of the marked graph and the initial projection position of the marked graph, thereby ensuring that the projection image displayed on the deformed projection screen does not deform, and ensuring that the display effect of the projection image is relatively good.

Description

technical field [0001] The present disclosure relates to the field of projection display, and in particular, to a correction method of a projected image and a laser projection device. Background technique [0002] At present, laser projection equipment can project and display projected images on a projection screen. However, if the projection screen is deformed, the projected image projected and displayed by the laser projection device on the projection screen will be deformed, resulting in poor display effect of the displayed projected image. SUMMARY OF THE INVENTION [0003] Embodiments of the present disclosure provide a method for calibrating a projected image and a laser projection device, which can solve the problem of poor display effect of the projected image displayed in the related art. The technical solution is as follows: [0004] In one aspect, a method for correcting a projected image is provided, applied to a laser projection device, the method comprising:...
