The invention relates to the technical field of real-time driving obstacle avoidance systems and methods, in particular to a real-time driving obstacle avoidance system and method of a dynamic self-adaptive SSVEP brain-computer interface, and the system comprises a visual evoked potential: the visual evoked potential electrophysiological phenomenon stimulates the retina with a flash or pattern with a certain intensity in the field of view, and the visual evoked potential is used for generating a real-time driving obstacle avoidance signal; a potential change can be recorded in a visual cortex or an occipital area outside the skull; and an SSVEP brain-computer interface which is a visual evoked potential, and when human eyes are subjected to visual stimulation with a constant frequency, a data processing module is used. The device can be switched in real time between the two modes of information collection through the brain or information collection through the sensor, driving safety is guaranteed, meanwhile, the two modes are matched with each other, high-end intelligent control can be achieved, driving fun and convenience are brought to people, and the long-time use of a precision part, namely a related sensor, can be effectively reduced.
本发明涉及实时驾驶避障系统及方法技术领域,具体为一种动态自适应SSVEP脑机接口的实时驾驶避障系统及方法,包含:视觉诱发电位:视觉诱发电位电生理现象,在视野范围内,以一定强度的闪光或图形刺激视网膜,可在视觉皮层或头颅骨外的枕区记录到电位变化;SSVEP脑机接口:视觉诱发电位,当人眼受到一个恒定频率的视觉刺激时,数据处理模块。本发明带来了使得装置可以在以大脑进行信息采集或传感器进行信息采集的两种方式之间进行实时切换,保证驾驶的安全性,同时两者相互配合,既能实现高端智能控制给人们带来的驾驶乐趣和方便的同时,还能有效的减少相关传感器这一精密零件的长时间使用。
