Example Embodiment

[0036] According to an embodiment of the present invention, this step can be performed by a combination of the growth of the connected domain and the skin color judgment.

[0037] In spatial interaction, the hand is often located in the foreground area of ​​the image, so the depth it produces is the largest, so find the pixel corresponding to the maximum depth, determine it as the pixel of the hand position, and then grow in all directions Area, if the pixels in the neighborhood of the pixel meet certain rules, these pixels are regarded as the same area. The rule should ensure that all the pixels in the hand area in the image are segmented. For example, if the absolute value of the gray difference between two adjacent pixels is less than a specified threshold, the two adjacent pixels can be determined The pixels are located in the same connected domain.

[0038] Then, you can continue to use the skin color judgment method to segment the accurate hand area. This method is to obtai...

Abstract

The invention discloses a space interaction method of mobile equipment with the human-computer interaction capacity. The method includes the steps of rebuilding a depth map of an image according to the two-dimensional image shot by the mobile equipment in real time; performing region segmentation on the depth map to obtain a human body position region in the depth map; mapping the human body position region in the depth map to a virtual scene; and detecting whether the human body position in the virtual scene collides with other objects in the virtual scene, if the collision happens, determining a body language according to the temporal space change of the human body position in the virtual scene, and the virtual scene making response according to the body. According to the method, accuracy and timeliness of space interaction can be improved.

Description

technical field [0001] The invention relates to the fields of image processing, three-dimensional image reconstruction, human-computer interaction and computer application, and in particular to a spatial interaction method of a mobile device. Background technique [0002] The spatial interaction technology of mobile devices is to use mobile devices with human-computer interaction capabilities (such as mobile phones, IPads, etc.) for spatial interaction, so that virtual objects in mobile devices can make corresponding responses according to human instructions. figure 1 It is a schematic diagram of the existing spatial interaction technology of mobile devices. Such as figure 1 As shown, there is an image of a cat displayed on the mobile device. Through the spatial interaction of the mobile device, we can make a fake grab gesture with our hands in front of the mobile device (where the camera can shoot), and the mobile device passes This gesture is recognized so that it shows ...
