Stereoscopic vision imaging device and stereoscopic vision stimulation equipment

Abstract

The invention discloses a stereoscopic vision imaging device and stereoscopic vision stimulation equipment. The device comprises a mirror used for converting the transmission direction of the light beams of a left-eye image and the light beams of a right-eye image from a horizontal direction to a vertical direction, a left-eye light path channel extending along the vertical direction and used for receiving and transmitting the light beams of the left-eye image reflected by the mirror and carrying out imaging on the exit surface of the left-eye light path channel, a right-eye light path channel extending along the vertical direction and used for receiving and transmitting the light beams of the right-eye image reflected by the mirror and carrying out imaging on the exit surface of the right-eye light path channel, and a support device on which the left-eye light path channel and the right-eye light path channel are arranged movably along the left-right direction and the vertical direction and the mirror is also arranged. The device helps to provide real stereoscopic vision stimulation close to that accepted by the human eye, and provides a novel visual basic research means for related research and test of the visual cortex area in a high-magnetic-field environment.

Description

technical field [0001] The invention relates to the field of magnetic resonance imaging, in particular to a stereoscopic vision imaging device for stereoscopic vision stimulation equipment and the stereoscopic vision stimulation equipment with the stereoscopic vision imaging device. Background technique [0002] The information decoding of the visual function of the human brain has always been a frontier field and a hot issue in brain science research, especially the study of how the brain areas related to the visual function of the human brain will respond to the images seen, and a series of key results have been achieved. The generation of human vision includes two processes: the reflected light of the object is refracted and imaged on the retina through the optical structures in the eye such as the cornea and lens; and then the photoreceptor cells on the retina provide nerve signals to the relevant visual areas of the brain through the optic nerve. form our vision.

AI Technical Summary

Problems solved by technology

[0004] Existing devices that provide visual signals generally have large errors due to defects in their imaging systems and calibration biases

Moreover, the provided visual stimulation signals are all planar, which is quite different from the real visual stimulation received by the human eye, which greatly limits the accuracy and diversity of the test.
