Embodiment Construction

[0062] The embodiments of the present invention will be described in detail below. It should be noted that the described embodiments are intended to facilitate the understanding of the present invention, and do not limit the present invention.

[0063] like figure 1 Shown, technical scheme of the present invention is as follows:

[0064] Step 1: Image acquisition: Continuously collect image data through the image acquisition device to update the data cache, and the acquired image is a color image, which is used to judge the user's operation gesture;

[0065] Step 2: Image denoising: read data from the data cache, perform filtering, and remove random noise introduced in the image;

[0066] In order to eliminate the influence of ambient light on the collected images, the present invention adopts the area average method to filter the original image, and eliminates the influence of noise on feature object extraction under different illumination models. use image 3 The mask sho...

Abstract

The invention relates to the technical field related to machine vision, particularly to a human-computer interaction method based on machine vision, comprising the following steps of: an image obtaining step for continuously acquiring image data through an image acquisition device to update data cache; an image denoising step for reading the data from the data cache, filtering the read data and removing random noise introduced into the image; a feature object extraction step for detecting a feature object in the denoised image, and marking the detected feature object with distinct mark; and astep of gesture identification step for analyzing the motion trail of the feature object extracted by the feature object extraction step, and executing corresponding machine instructions according tothe result of analysis on the motion trail. The human-computer interaction method based on the machine vision provides a complete system solution, so that human can interact with the machine in real time, application limit of the prior touch technology is solved, and the human-machine interaction can be more natural.

Description

technical field [0001] The invention relates to the technical field related to machine vision, in particular to a human-computer interaction method based on machine vision. Background technique [0002] With the development of human-computer interaction technology, multi-touch technology has become a hot application. APPLE has introduced multi-touch technology into its newly launched IPAD, and large-size electronic whiteboards have also realized support for multi-touch technology. As the post-mouse era enters people's daily life, the naturalness of interaction is particularly important, and interactive technology is gradually developing from an interactive era to a more natural interactive era that conforms to ergonomics. [0003] Apple's research on ergonomics shows that human-computer interaction is not suitable for vertical screens. From the actual operation summary, there are similar conclusions. There are two main reasons: one is that the arm is raised for a long time...
