Example one
Fig. 1 is a flow chart of a light film adjusting method according to a first embodiment of the present invention. The technical scheme of the embodiment can be suitable for the condition of adjusting the optical film. The method can be executed by the light film adjusting device provided by the embodiment of the invention, and the device can be realized in a software and/or hardware manner and is configured to be applied to a projection touch device, such as a desktop projection touch device or any space projection device. The method specifically comprises the following operations:
and S110, respectively arranging a reference object at least one preset position of the projection plane.
Taking laser as an example, in the projection touch control, laser is emitted to a projection plane through a laser, the laser is connected with an infrared camera for power supply, the laser can adopt a linear laser, and the emitted laser is planar light to form an optical film. A light film emitted by the linear laser is irradiated on a projection plane to form a light band which is shot by the infrared camera, and the projection plane is a software interface formed in a projection mode. In the embodiment of the present invention, the type of light is not specifically limited, and may be any light that can realize projection touch, such as laser, infrared ray, or ultrasonic wave, and may be selected according to needs.
The method includes the steps that a reference object is arranged at least one preset position of a projection plane, namely the reference object is arranged at each preset position, the preset position can be arranged at any position of the projection plane, the preset position is located in a preset area of the projection plane, the preset area can be the projection plane between a center line and a lower edge or the projection plane between the center line and an upper edge, the center line is located between the upper edge and the lower edge of the projection plane, the distance between the center line and the upper edge and the distance between the center line and the lower edge are equal, and the center line and the upper edge or the lower edge are parallel. Preferably, the preset area is a projection plane between the center line and the lower edge, that is, a middle-lower area of the projection plane, and the middle-lower area is configured to ensure that light in the projection plane between the upper edge and the reference object meets a touch condition, where the light meets the touch condition, that is, the light is higher than the projection plane by a certain height, and for example, the certain height may be 1-3 mm. Specifically, before the reference object is respectively arranged at least one preset position of the projection plane, the method further comprises the following steps: determining a preset area in the projection plane, and determining at least one preset position in the preset area.
For example, the preset positions may be two end positions of the lower edge of the projection plane and a middle position between the two end positions, and respectively setting the reference object at least one preset position of the projection plane includes: determining two end positions of the lower edge of the projection plane and the middle positions of the two end positions as three preset positions, and respectively arranging reference objects at the three preset positions. The heights of the reference objects arranged at the two end positions of the lower edge of the projection plane are the same, and the heights of the reference objects arranged at the two end positions are greater than the height of the reference object arranged at the middle position of the two end positions. Preferably, the height range of the reference objects arranged at the two end positions of the lower edge of the projection plane is 2-5mm, and the height range of the reference objects arranged at the middle position of the two end positions of the lower edge of the projection plane is 1-3 mm.
And S120, adjusting the direction of the light film until the reflected light of the reference meets a preset condition.

In the condition that the optical film is already horizontal or has an acceptable inclination angle, only the vertical direction of the optical film needs to be adjusted, and for example, the vertical direction adjusting screw can be controlled to be in a loose state by adjusting the vertical direction adjusting screw. The vertical direction of adjusting the light film, namely the angle of emergent light of the laser, is adjusted upwards, the vertical direction of the light film is increased, the light film and the projection plane are adjusted to be not provided with an intersection point with the projection plane by the existence of the intersection point, namely the light film is adjusted to not be irradiated on the projection plane by being irradiated on the projection plane. The touch operation is affected by the fact that the vertical direction of the optical film is too high, therefore, the vertical direction of the optical film cannot be adjusted to be high without limit.

The horizontal direction of the optical film can be adjusted, for example, by adjusting a horizontal direction adjusting screw, until the oblique optical tape is adjusted to the horizontal direction optical tape, by controlling the horizontal direction adjusting screw to be in a loose state.
Further, adjusting the direction of the optical film until the reflected light of the reference meets a preset condition, comprising:
and adjusting the direction of the light film until the intensity of the reflected light of the reference object with the height higher than the preset height in the reference object is higher than a first preset intensity threshold value, and/or the intensity of the reference object with the height lower than the preset height in the reference object is lower than a second preset intensity threshold value. The first preset intensity threshold may be greater than or equal to the second preset intensity threshold. The height of the reference object is set within a preset height range, within which the height of the reference object is set. The preset height can ensure that the use of a user is not influenced under the condition that the projection plane is covered with the projection film to enable the projection plane to be thickened.

S240, setting different colors of the preset boundary according to the light intensity of the reflected light of the reference object.
For example, when the intensity of the reflected light of the reference object is less than the second preset intensity threshold, the color of the boundary covering the preset position of the projection area of the reference object is set to be blue, the intensity of the reflected light of the reference object is greater than the first preset intensity threshold, and the color of the boundary covering the preset position of the projection area of the reference object is set to be green, and the specific set color is not limited herein.
And S250, adjusting the direction of the light film until the color of the preset boundary meets the preset color.
