Problems solved by technology

However, when the target is placed in a more complex background, target recognition errors may occur. For example, if a target with stripes on the surface is placed in front of a striped background, binocular vision recognition is prone to errors. Therefore, line-type laser assistance is often used at present. Scanning to exclude interference from complex backgrounds
In addition, because the binocular vision system needs to process a large amount of image information, it is difficult to track the target in high-speed real-time space coordinates

Abstract

The application relates to a plane interaction system and method based on binocular vision recognition. The plane interaction system comprises an imager and a processor, wherein the imager comprises two imaging components which are distributed by a relatively fixed space relationship, and the two imaging components are used for capturing images of targets at the same time; and the processor is configured to process image parallax errors of feature points of the targets captured at the same time, computing space coordinates of the feature points, confirming the space relationship between the feature points and a set interaction plane according to the space coordinates of the feature points, and outputting the interaction response.

Description

technical field [0001] The present invention relates to a plane touch control system, and more particularly, to a plane interaction system and method based on binocular visual recognition. Background technique [0002] The flat touch control system is a computer input method. Different from the traditional mouse and keyboard input methods, the planar touch control system calculates the coordinates of the touch points and inputs them to the computer to achieve the purpose of directly operating the virtual objects in the computer. At present, many known technologies have been applied to the planar touch control system. [0003] Resistive touch screen technology uses pressure sensing for control, and is a touch technology widely used on touch terminals. The working principle is that on a transparent substrate coated with a metal oxide conductive layer on the upper surface, a layer of transparent plastic plate coated with a metal oxide conductive layer on the lower surface is ...
