Embodiment Construction

[0045] In order to have a further understanding and understanding of the structural features of the present invention and the achieved effects, the preferred embodiments and accompanying drawings are used for a detailed description, as follows:

[0046] like figure 1 As shown in the present invention, a method for marking connected domains for projection interaction systems includes the following steps:

[0047] The first step is the connected domain labeling of the first frame image. The image video is acquired, and the connected domains of the first frame of the image video are marked by using the existing technology to obtain a marked map corresponding to the sub-rows.

[0048] The connected domain mark assigns a different integer label (such as: 1, 2, 3, ...) to each connected domain (foreground pixel blocks connected to each other) in the image to ensure that different connected domains have different labels, while the same Each pixel in the connected domain has the sam...

Abstract

The invention relates to a connected domain marking method used for a projection interaction system, and solves the defect of low efficiency of the connected domain marking method in comparison with the method in the prior art. The connected domain marking method comprises the following steps that the connected domain of a first frame of image is marked, an image video is acquired, the connected domain of the first frame of image of the image video is marked and a marked graph corresponding to sub-rows is obtained; new pixels and disappear pixels are acquired; marking result correction is performed on the previous frame of image based on the disappear connected domain; and marking result correction is performed on the current frame of image based on the new connected domain. The marking function of the connected domain in the binary image can be rapidly completed in processing successive frames of images.

Description

technical field [0001] The invention relates to the technical field of computer vision processing, in particular to a connected domain marking method for a projection interaction system. Background technique [0002] Human-computer interaction technology is a crucial field in computer science, and its development history basically represents the development history of computers. From the clumsy switch system on the earliest mainframes to the early keyboard and mouse, and now the very popular touch screen, the development speed of human-computer interaction technology is changing day by day. In recent years, due to the rapid development of computer vision technology and the emergence of new sensors (such as depth cameras Kinect, LeapMotion, etc.), various convenient human-computer interaction methods emerge in endlessly. [0003] Kinect is a depth-sensing camera developed by Microsoft. Through a well-designed algorithm, it can perceive the distance from the target to the c...
