Embodiment 1

[0047] figure 1 It is a flow chart of a light film adjustment method provided in Embodiment 1 of the present invention. The technical solution of this embodiment can be applied to the situation of adjusting the light film. The method can be performed by a light film adjusting device provided in an embodiment of the present invention, which can be implemented in the form of software and / or hardware, and configured for application in a projection touch device, such as a desktop projection touch device or any space Projection equipment. The method specifically includes the following operations:

[0048] S110. Set a reference object at at least one preset position on the projection plane.

[0049] Taking laser as an example, in the projection touch, the laser is emitted to the projection plane through the laser. The laser is connected to the infrared camera for power supply. The light film emitted by the laser is hit on the projection plane to form a light band, which is captu...

Embodiment 2

[0064] figure 2 It is a flow chart of a light film adjustment method provided by Embodiment 2 of the present invention. On the basis of the foregoing embodiments, the embodiment of the present invention further optimizes the operation after at least one preset location is determined in the preset area.

[0065] Correspondingly, the method of this embodiment includes:

[0066] S210. Determine a preset area on the projection plane.

[0067] S220. Determine at least one preset location in the preset area.

[0068] S230. Determine preset boundaries at the at least one preset location respectively.

[0069] The preset position covers the projection area of ​​each reference object. For example, it can be a rectangular frame including the reference object projection area. A rectangular frame of any size can be drawn in the preset area. The rectangular frame is the preset boundary of the preset position, and the rectangle Boxes cover the projected area of ​​each reference object....

Embodiment 3

[0076] image 3 It is a structural block diagram of a light film adjusting device provided in Embodiment 3 of the present invention. The device is used to implement a light film adjustment method provided in any of the above embodiments. The unit includes:

[0077] A reference object setting module 310, configured to set reference objects at least one preset position on the projection plane;

[0078] The light film direction adjustment module 320 is configured to adjust the light film direction until the reflected light of the reference object satisfies a preset condition.

[0079] In the embodiment of the present invention, reference objects are respectively set at at least one preset position of the projection plane; the direction of the light film is adjusted until the reflected light of the reference objects meets the preset conditions. Automation simplifies the adjustment process, improves adjustment efficiency, avoids interference after the projection film is placed, ...

Abstract

The embodiment of the invention discloses an optical film adjusting method, a device, a terminal and a storage medium. The method comprises the following steps: a reference object is respectively arranged atleast one preset position of a projection plane; The direction of the light film is adjusted until the reflected light of the reference satisfies a preset condition. The embodiment of the invention realizes the automation of the light film adjustment, improves the adjustment efficiency and improves the reliability of the light film.

Description

technical field [0001] Embodiments of the present invention relate to projection touch technology, and in particular to a method, device, terminal and storage medium for adjusting an optical film. Background technique [0002] Projection touch mainly uses laser imaging technology. Laser imaging technology uses lasers to emit laser light. The emitted laser light is planar to form a light film. The light film is 1-3mm higher than the projection plane and has a thickness of about 1mm. When a finger or any opaque object touches the projection plane, the light is reflected to an image sensor set above the projector. Through precise calculation of the photoelectric position, the touch coordinates are obtained to realize the operation of the projection plane icon. [0003] Different placement positions of the laser produce different angles of the light film, and the light film has different angles with the projection plane. The projection plane has two edges along the emission dir...
