Abstract

The embodiments of the invention provide a projection touch control method and apparatus, and a projection touch control device. The method comprises the steps of acquiring effective distance measurement data that are obtained by measurement of each of at least two distance measurement sensors to a to-be-measured object, wherein the at least two distance measurement sensors are distance measurement sensors included in a distance measurement sensor array, and the to-be-measured object is an object performing a touch control operation on a projection area; based on the effective distance measurement data, calculating to obtain a position coordinate of the to-be-measured object in the projection area; and according to the position coordinate, generating a corresponding touch control instruction. The effect of reducing the production cost of the projection touch control device is implemented.

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...
