Abstract

The invention discloses laser projection equipment and a prompting method thereof, and belongs to the field of projection display. If the laser projection equipment detects that the target position of the target object is in any threshold detection range, a prompt picture can be generated according to the target position, and the prompt picture is displayed on the main picture of the projection screen. The prompt picture comprises the text information used for indicating the target position of the target object and / or the image information used for identifying the relative position of the target object and the laser projection equipment, so the target object can visually see the relative position between the target object and the laser projection equipment, and the prompt flexibility of the target object is improved. Meanwhile, the user can get away from the projection screen in time under the prompt of the prompt picture so as to protect the eyes of the user.

Description

technical field [0001] The present disclosure relates to the field of projection display, in particular to a laser projection device and a prompting method thereof. Background technique [0002] At present, after the laser light emitted by the laser projection device is projected onto the projection screen, the projected image can be projected onto the projection screen. However, since the laser light emitted by the laser projection device has relatively high brightness, when the user is close to the projection screen, the laser light may cause damage to human eyes. Contents of the invention [0003] Embodiments of the present disclosure provide a laser projection device and a prompting method thereof, which can solve the problem in the related art that laser light may cause damage to human eyes. Described technical scheme is as follows: [0004] In one aspect, a prompting method for a laser projection device is provided, the method comprising: [0005] receiving the de...
