Problems solved by technology

However, the infrared touch screen in the related art can only recognize the touch points that block the scanning light path in all scanning directions at the same time, but cannot recognize the touch points that do not block the scanning light path in all scanning directions at the same time, so it is difficult to recognize the touch points with a width smaller than two adjacent lines. Touch points for spacing between parallel scanning light paths

Embodiment Construction

[0033] In order to facilitate understanding, the following combined instructions are attached to the instructions to describe the touch point recognition method provided by the embodiments of the present invention.

[0034] First introduce some concepts that may be involved in the embodiments of the present invention.

[0035]1. Scanning direction: In 1 pair of d (d≥1) scanning mode, each scanning light has a different angle for specific lamps; for a specific lamp, the corresponding D -strip scanning light path of the light path is every Angles, we call it a scan direction. Therefore, 1 pair of D scan methods will have D scan directions. Each scanning direction can correspond to a set of parallel light paths with the same slope (that is, scanning light road). Please refer to figure 2 and image 3 ,, figure 2 In the 1 -to -2 scanning method, the two scan directions corresponding to the long launch side 11; image 3 In the 1 -to -2 scanning method, two scan directions corresponding to...

Abstract

The invention discloses a touch point recognition method, a touch point recognition device, a storage medium and a touch control device, which relate to the field of touch control and are used for recognizing touch points with a small area. The method includes: performing scanning in multiple scanning directions to obtain at least one touch area in at least one scanning direction; judging whether the number of scanning directions in which the number of touch areas in the multiple scanning directions is not zero is less than the number of effective touch areas Threshold, if not, mark the touch area in each scan direction as a different valid touch area, and add an invalid touch area in each scan direction; select a touch area from each scan direction at a time to get the sorting Combination; superimpose the valid touch areas in the sorted combination to obtain at least one overlapped area, and judge whether each overlapped area is the overlapped area of ​​all valid touch areas in the sorted combination, if so, add the corresponding overlapped area Determined to be a real touch point.

Description

Technical field [0001] The invention involves the field of touch technology, especially for a touch point recognition method, touch point recognition device, computer readable storage medium and touch device. Background technique [0002] The infrared touch screen is an electronic device that can detect the touch operation throughout the touch screen area. It simplifies the human -computer interaction method and has the advantages of simple production process, low production cost, convenient installation, high reliability and other areas. Applications. [0003] In related technologies, infrared touch screens are usually rectangular structures, such as figure 1 Show, the infrared touch screen consists of a long launch side 11, a long receiving edge 11 ', a short launch edge 12, and a short -receiving edge 12'. There are several lamps 13 on the edge of each launch, and there are several receiving light 13 'on the corresponding receiving side. Usually a pair of multi -way scan, that...
