Problems solved by technology

At present, the above-mentioned indoor space is mainly projected using a front projection device, that is, the image is projected on the projection surface from the front of the screen and other projection surfaces. The traditional front projection device cannot be freely operated, for example, its projection area is preset. Therefore, the traditional front projection device is not flexible enough, which often limits the performance of the lecturer or the host.

Embodiment Construction

[0040] Below in conjunction with accompanying drawing and preferred embodiment the present invention is described in further detail:

[0041] Please refer to figure 1 A preferred embodiment of the front projection control system 1 of the present invention includes a camera device 80 , a projector 90 and a control system 100 .

[0042] The photographing device 80 has multiple lenses, and the first lens of the photographing device 80 is used to photograph a target object. The projector 90 receives the image of the target object through the control system 100 and projects the received image of the target object on a projection area. The second lens of the photographing device 80 is used to photograph the projection area and transmit the obtained image of the projection area to the control system 100 . The control system 100 detects the image of the projection area to detect a specific gesture for operating the projection area. When the specific gesture is detected, the control ...

Abstract

The invention discloses a front protection control method, comprising the following steps: transmitting an image of a target object shot by a first projection device to a projector for projection to form a projection area; detecting the operation of a specific gesture on the projection area according to the image of a projection area shot by a second projection device, when the projection area is operated by the specific gesture, generating a first detection signal; retrieving a plurality of symbols to the projector for projection so as to form a plurality of control panels of the control symbols in the projection area according to the first detection signal; detecting the operation of the control symbols according to the image of the control panel shot by a third projection device; and when the control symbols are operated, generating a second detection signal corresponding to the operated control symbol; and carrying out corresponding control movement on the first projection device, the second projection device, the third projection device or the projector according to the second detection signal. The invention also provides a front projection control system; and by utilizing the front projection control system and method thereof, the projection of the target object can be flexibly controlled.

Description

technical field [0001] The invention relates to a front projection control system and method. Background technique [0002] Indoor spaces such as classrooms, venues, lecture halls, and auditoriums are important places for people to carry out collective activities. With the increase of indoor space, projection devices have gradually become an indispensable tool to provide students, participants, and audiences with another A "blackboard" makes up for the defects caused by the large space to some extent. At present, the above-mentioned indoor space is mainly projected using a front projection device, that is, the image is projected on the projection surface from the front of the screen and other projection surfaces. The traditional front projection device cannot be freely operated, for example, its projection area is preset. Therefore, the traditional front projection device is not flexible enough, which often limits the performance of the lecturer or the host. Contents of t...
