Abstract

The invention discloses a three-dimensional space imaging interaction method and a three-dimensional space imaging interaction based on ultrasonic wave. The three-dimensional space imaging interaction method is different from an existing holographic imaging technology. The method comprises the following steps: firstly establishing the three-dimensional coordinates of a space to generate a target three-dimensional space, and emitting ultrasound microbubbles capable of sensing with an ultrasonic wave field; then, forming the ultrasonic wave field in the target three-dimensional space through the ultrasonic wave, generating a potential well position in the target three-dimensional space, controlling the ultrasound microbubbles to move in the target three-dimensional space and to be stabilized at the position, simultaneously coloring the ultrasound microbubbles by adjusting laser, and thus forming a three-dimensional image in the target three-dimensional space. Furthermore, the three-dimensional images are converted into 3D pictures and the 3D pictures are shown for a user by continuously repeating the steps. Through the 3D pictures shown for the user in the method and the system, the user can be interactive with the 3D pictures, so that the user can feel the real touch of the 3D pictures in the interaction process, and the original structures of the three-dimensional images can also be maintained.

Description

technical field [0001] The invention relates to the technical field of three-dimensional space imaging interaction, in particular to an ultrasonic-based three-dimensional space imaging interaction method and system. Background technique [0002] With the development of science and technology, the interaction between electronic devices and users is constantly evolving from virtual to real. From the one-dimensional platform of Amazon's one-click delivery system, to the two-dimensional flat finger sliding operation of smartphones, to the three-dimensional gesture interaction platforms such as Leap motion and Kinect, the interaction between users and devices has become closer to reality. [0003] The traditional three-dimensional imaging method requires a fixed imaging plane, which can be a screen, water curtain, air curtain, etc., and uses the fixed imaging plane to reflect the light of the light source on the reflection plane that exists continuously and stably in space. to r...
