Embodiment Construction

[0033] In order to make the purpose, technical solution and advantages of the present disclosure clearer, the implementation manners of the present disclosure will be further described in detail below in conjunction with the accompanying drawings.

[0034] figure 1 is a schematic structural diagram of a laser projection device provided by an embodiment of the present disclosure, such as figure 1 As shown, the laser projection device may include a host 00 , a first pyroelectric sensing module 10 and a second pyroelectric sensing module 20 . The first pyroelectric sensor module 10 is located on the side of the upper surface of the host 00 away from the projection screen 001, and the second pyroelectric sensor module 20 is located on the side of the upper surface close to the projection screen 001. The upper surface is the side of the host 00 away from the bearing surface of the host 00 . The detection range of the first pyroelectric sensing module 10 does not overlap with the ...

Abstract

The invention discloses laser projection equipment and a control method thereof, and belongs to the field of projection display. And after the laser projection equipment receives the second infrared signal detected by the second pyroelectric sensing module, the display of the projection picture can be changed, so that the functions of the laser projection equipment are enriched. Moreover, after the laser projection equipment receives the first infrared signal detected by the first pyroelectric sensing module, the display of the projection picture is kept, so that the situation that the display of the projection picture is changed because the target object is not in the projection range of the laser projection equipment is avoided, and the watching effect of the target object is ensured.

Description

technical field [0001] The present disclosure relates to the field of electronic technology, in particular to a laser projection device and a control 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, the function of the laser projection device is relatively single. Contents of the invention [0003] Embodiments of the present disclosure provide a laser projection device and a control method thereof, which can solve the problem in the related art that the functions of the laser projection device are relatively single. Described technical scheme is as follows: [0004] In one aspect, a control method of a laser projection device is provided, the laser projection device includes a host, a first pyroelectric sensing module and a second pyroelectric sensing module; the first pyroelectric sensing...
