Abstract

The invention relates to a coordinate measuring apparatus and method thereof. Specifically, the method includes: using a plurality of light receiving parts and a small quantity of light emitting parts to firstly determine the path equations of each light emitting part corresponding to each light receiving part; and then using the determined path equations to request actual coordinates of more than one targets. As few number of light emitting sensors are used, so that not only the setting fees can be reduced, but also the maintenance cost can be greatly reduced, and simultaneously the service life of the product can be prolonged.

Description

【Technical field】 [0001] The present invention relates to a coordinate recognition device and method, specifically, a coordinate measuring device and a measuring method thereof which generate actual coordinates of one or more target objects at the same time by using a small number of light emitting sensors. 【Background technique】 [0002] Generally speaking, a touch screen refers to the following screen. Without using a keyboard, you can grasp its position by touching the text or a specific position on the screen (screen) with your hand or pointer (pointer), and you can use the built-in The software performs specific processing so that input data can be obtained directly from the screen. [0003] The touch screen is to add a device called "touch panel (touch panel)" on the screen of the ordinary monitor, so as to exert the touch function. Infrared rays invisible to the naked eye are irradiated on the left, right, top, and bottom of the touch panel, forming a large number of...
