3D microscopic real-time virtual observation and interaction system

Abstract

The invention relates to a 3D microscopic real-time virtual observation and interaction system, in particular to real-time or off-line virtual observation of micro-scale objects, and the system mainly comprises a binocular stereoscopic microscope observation platform, a virtual observation management module, a stereoscopic image alignment module, a parallax real-time adjustment module and a 3D observation module. According to the binocular stereoscopic microscope, stereoscopic image alignment is carried out on the images shot by the left camera and the right camera on the binocular stereoscopic microscope, so that the binocular stereoscopic microscope meets the stereoscopic display condition and only has parallax in the horizontal direction, and the parallax of an object is adjusted in real time during 3D observation, so that different people can feel the stereoscopic display effect; a mobile phone or a handle is used for enabling an observer to adjust parallax and change the position of an object to be observed in real time while carrying out stereoscopic observation, and the operability and convenience of the observation system are improved.

Description

technical field [0001] The invention relates to a 3D microscopic real-time virtual observation and interaction system, in particular to realizing real-time virtual observation of tiny-scale objects by alignment and parallax adjustment of stereoscopic images, and real-time interaction with the virtual observation system can be realized through a mobile phone or a handle. Background technique [0002] At present, operators usually observe micro-scale objects (such as MEMS microstructures, tiny parts, tiny biological tissues, cells, etc.) The eyes need to be aligned with the eyepiece, and if you keep a fixed posture for a long time, it is easy to cause fatigue and discomfort. You can also display the two-dimensional images under the microscope in real time through the computer. For objects with complex surface shapes, their depth information cannot be displayed well. Reduce positioning accuracy. [0003] Compared with traditional 2D movies, the display effect of 3D movies is m...

Yang Zesheng et al. (2003) installed cameras in the two optical paths of the stereomicroscope, and displayed the images captured by the cameras on two monitors. An optical system was placed in front of the monitors. Chen Muwang et al. (2010) directly placed the 3D display device on the It is divided into two parts to show the video captured by two cameras installed on the optical path of the stereo microscope. The human eye can observe the 3D image at a specific position, but they cannot guarantee that the installation angles of the left and right cameras are exactly the same. There is no alignment of the captured left and right images; the left and right images are displayed on the left half and right half of the display screen respectively, but the relative positions of the left and right images cannot be adjusted. The parallax is only related to the relative position in the left and right images, which means that the observer cannot adjust the interpupillary distance of the eyepieces of the stereo microscope, and the stereoscopic display effect may not be observed or the stereoscopic display effect is not obvious; due to the field of view of the stereo microscope The scope is small, only a part of the object to be observed can be observed, and an observer cannot precisely adjust the position of the object to be observed while stereoscopically observing, which reduces the convenience and comfort of the observation system
