Problems solved by technology
The existing touch technology (including various methods of image acquisition and processing) cannot reliably, effectively and conveniently realize the non-contact aerial operation of buttons, keyboards and touch screens
Resistive, surface acoustic wave, infrared and other touch screens must be touched to operate; the distance for capacitive screens to achieve non-contact operation is very short (generally no more than 3 cm), easy to misuse, and not practical; devices using image processing technology are not inevitable False occlusion means that the application site is difficult to install

Embodiment Construction
[0047] In this embodiment, a simplified structure of infrared three-dimensional scanning is to adapt to the application requirements of special occasions (the left and right sides or the upper and lower sides cannot be blocked) and reduce the number of components. Extended to L×D infrared pair tubes, such as figure 1 As shown, a cuboid infrared scanning area is set up. In order to meet the application requirements of special occasions (the left and right sides or the upper and lower sides cannot be blocked) and reduce the number of components, only the bottom surface and the top surface (or the left and right sides) of the cuboid infrared scanning area are respectively arranged with L ×D infrared emitting tubes and L×D infrared receiving tubes; L-k infrared emitting tubes in front of the bottom edge of the c-th layer and L-k infrared emitting tubes behind the top edge form the oblique direction of the c-th layer of the oblique L-k beam scanning line In the infrared scanning la...

The invention discloses an infrared three-dimensional scanning simplified structure. L * D infrared transmitting tubes and L * D infrared receiving tubes are arranged on the bottom surface and the topsurface of a cuboid infrared scanning area respectively; a c-th inclined infrared scanning layer of an inclined L-k beam scanning line is formed by L-k infrared transmitting tubes in front of the bottom edge and L-k infrared transmitting tubes behind the top edge of the c-th layer, and a vertical infrared scanning layer of a c-th layer of a vertical L-2k beam scanning line is formed by L-2k infrared transmitting tubes in the middle of the bottom edge and L-2k infrared transmitting tubes in the middle of the top edge of the c-th layer; according to the infrared aerial non-contact touch screen,an infrared three-dimensional scanning simplified structure is arranged in front of a display screen in parallel; according to the infrared aerial key, an infrared three-dimensional scanning simplified structure is arranged in parallel and covers the front of the plane where all keys are located. According to the invention, three-dimensional aerial positioning and three-dimensional touch control,non-contact aerial touch control of the display screen and non-contact aerial pressing of the keys can be achieved, so that the problem of cross infection of viruses and bacteria caused by clicking the touch screen and the keys in public places is solved.
Description
technical field [0001] The invention relates to the field of computer three-dimensional interaction, mainly relates to three-dimensional positioning and aerial touch technology, and specifically relates to the realization structure and method of three-dimensional aerial positioning and non-contact aerial touch based on infrared scanning. Background technique [0002] Three-dimensional interaction has always been an important topic in the field of computer intelligent interaction research. One of the technical difficulties in realizing 3D interaction is the accurate and reliable positioning of the human body (especially arms, hands, and fingers). At present, 3D aerial positioning is mainly realized by 3D image sensor, and Microsoft's Kinect is its typical representative. This positioning technology still has problems such as inaccurate positioning and wrong positioning, especially the inherent defect that its positioning is directional and cannot be solved. [0003] On the ...
