Embodiment 1

[0027] see Figure 1 to Figure 2 , the figure shows a multi-touch-based object recognition method for an exhibition hall touch screen provided by Embodiment 1 of the present invention, which mainly includes: the hardware system in the object recognition method includes: a capacitive touch frame, a display, a computer host, and base, the capacitive touch frame is set on the display, the computer mainframe is electrically connected to the display and the capacitive touch frame, the display is set on the base; an induction module is set on the base 1. The sensing module 1 is signal-connected to the capacitive touch frame, the display and the computer host respectively, the sensing modules 1 are provided in multiples, and each sensing module 1 is provided with four Sensing point: By identifying different sensing points in the sensing module 1 through the software system in the object recognition method, the modules corresponding to different sensing points can be identified, and t...

Embodiment 2

[0035] see Figure 1 to Figure 2, the figure shows a multi-touch-based object recognition method for an exhibition hall touch screen provided by Embodiment 2 of the present invention. On the basis of the above-mentioned embodiments, this embodiment further makes the following technical solutions as improvements: The software system in the object recognition method can recognize the angle of each of the sensing modules 1, and obtain the rotation direction of each of the sensing modules 1 in real time, so as to identify the application scene corresponding to the corresponding sensing module 1; The sensing module 1 is provided with four legs 2, and each of the legs 2 corresponds to one sensing point; the four legs 2 take the center of the entire sensing module 1 as the center of a circle, and two of the legs 2 and the center of the circle are on a straight line, and the other two legs 2 are distributed on both sides of the straight line; in the object recognition method, the radi...

Embodiment 3

[0037] see Figure 1 to Figure 2 , the figure shows a method for recognizing objects on a touch screen in an exhibition hall based on multi-touch provided by Embodiment 3 of the present invention. On the basis of the above-mentioned embodiments, this embodiment further makes the following technical solutions as improvements: The software system in the object recognition method recognizes the position of the support foot 2 through the capacitive touch frame, takes any two coordinate points as diameters, compares the diameter calculated by the software system with the diameter of the built-in module, and the error Within a certain range, virtualize a circle with the center of the sensing module 1, calculate whether there are sensing points on the circle in the periphery, and count the sensing modules 1 that meet the characteristic values ​​into the identified sensing module 1 array , and calculate the recognition rate with the radius of the circle and the relative position error...

Abstract

The invention provides an exhibition hall touch screen object recognition method based on multi-point touch. A hardware system of the exhibition hall touch screen object recognition method comprises acapacitive touch frame, a display, a computer host and a base, the capacitive touch frame is arranged on the display, the computer host is electrically connected with the display and the capacitive touch frame, and the display is arranged on the base; a plurality of sensing modules are arranged on the base, the sensing modules are in signal connection with the capacitive touch frame, the displayand the computer host, and each sensing module is provided with four sensing points; different sensing points in the sensing modules are recognized through a software system in the object recognitionmethod, modules corresponding to the different sensing points can be recognized, and corresponding digital content is displayed on a human-computer interface. The method solves the technical problemsin the prior art that when a touch screen for an exhibition hall is in use, a user can only touch a designed program button through fingers and cannot connect a real object or a real object model introduced by image and text with digital content.

Description

technical field [0001] The invention relates to an object recognition method, in particular to a multi-touch-based object recognition method on a touch screen in an exhibition hall. Background technique [0002] Most of the interactive exhibition halls in the exhibition hall use the touch screen as the human-computer interaction interface. The content displayed is mostly graphic materials, audio and video playback. Users can only touch the designed program buttons with their fingers, click or slide to view the digital For content display, it is impossible to connect the physical objects or physical models introduced in pictures and texts with digital content. Contents of the invention [0003] In view of this, the present invention provides a multi-touch-based object recognition method for an exhibition hall touch screen to solve the problem that when using a traditional exhibition hall touch screen, the user can only touch the designed program button with a finger, click ...
