Interaction method and interaction system, and acquisition method of relative depth

Abstract

The invention discloses an interactive method and an interactive system, and an acquisition method of a relative depth. The interactive method comprises the steps that a laser image containing an interactive object in target space is collected; the relative depth between the laser image and a reference laser image is computed, wherein the reference laser image is a pre-collected laser image which does not contain the interactive object in the target space; the relative depth between the laser image and the reference laser image is used to extract an image part of the interactive object from the laser image; and the image part of the interactive object is recognized, and a corresponding control instruction is generated according to a recognition result. In this way, the interactive method, the interactive system and the acquisition method of the relative depth disclosed by the invention can avoid cumbersome computation steps brought by computation of a direct depth and can increase the speed of depth acquisition and interaction.

Description

technical field [0001] The invention relates to the technical field of three-dimensional interaction, in particular to an interaction method, an interaction system, and a relative depth acquisition method. Background technique [0002] Human-Computer Interaction (HCI for short) refers to the process of information exchange between humans and computers using a certain dialogue language to complete certain tasks in a certain interactive way. [0003] Since two-dimensional images can only reflect the color, texture and other information of people (interactive objects), it is generally adopted to realize human-computer interaction by using three-dimensional depth images, such as the recognition of gestures and actions by using human body depth images Somatosensory interaction, etc. [0004] Generally speaking, somatosensory interaction needs to obtain the depth image of the target space to obtain the depth information of the target space. Depth images can be obtained through d...

Problems solved by technology

Depth images can be obtained through depth cameras. Currently, structured light depth cameras and TOF (Time of Flight) cameras are commonly used; no matter what kind of camera it is, it is impossible to directly obtain the depth of the measured target, but it needs to collect images through the camera. Further calculations to obtain the target depth value, these calculation steps are cumbersome and time-consuming, resulting in a large delay in the current somatosensory interaction, unable to achieve real-time experience
