Problems solved by technology

[0004] However, in the current process of realizing the touch interaction function of the projection screen, both the infrared light source and the infrared camera are indispensable, which increases the production cost of the projection touch device to a certain extent.
Moreover, the volume of the infrared light source and the infrared camera is relatively large, occupying the internal space of the projection touch device, and increasing the difficulty of hardware integration of the projection touch device

Abstract

Embodiments of the present invention provide a projection touch method, device, and projection touch equipment. The method includes: obtaining effective distance measurement data measured by at least two distance measurement sensors for the target to be measured, wherein at least two distance measurement sensors The sensor is: the ranging sensor included in the ranging sensor array, and the target to be measured is an object that performs touch operation on the projection area; based on the effective ranging data, the position coordinates of the target to be measured in the projection area are calculated; corresponding touch commands. In order to reduce the production cost of the projection touch device.

Description

technical field [0001] The present invention relates to the field of virtual touch technology, in particular to a projection touch method, device and projection touch equipment. Background technique [0002] At present, there are many projectors, miniature projectors and other products on the market, which can project images and / or videos onto a projection screen to form a projection screen, so as to realize the display of images and / or videos. Due to the need for convenience, users increasingly hope that they can directly interact with the projection screen by touch. [0003] At present, the implementation process of the touch interaction function of the projection screen is generally as follows: the projection touch device uses an infrared light source to emit a sensing area overlapping with the projection screen; and uses an infrared camera to monitor in real time whether the infrared distribution of the sensing area changes; When the infrared camera detects that the inf...
