The invention discloses an omnidirectional fisheye image feature tracking and extracting method based on a non-parallel virtual binocular, and the method comprises the steps: constructing a four-eye fisheye camera system, obtaining the relative pose transformation based on a pre-calibration external parameter, predicting the pose based on a uniform speed model or IMU pre-integration, and constructing a re-projection error function through common-view feature points. According to the invention, by constructing four groups of virtual binocular combinations, on the premise of not increasing the number of physical cameras, eight-view-angle equivalent coverage is realized, so that a high-overlapping common-view area is formed between adjacent cameras; on the basis of a pre-calibrated external parameter and an MEI fisheye model, a spherical epipolar line is directly generated for a distorted image to carry out matching search, and meanwhile, a time sequence-space two-dimensional fault-tolerant mechanism is put forward for challenges of shielding and environmental interference: according to a dynamic direction switching design, when a tracking feature number is lower than a threshold value due to shielding in a camera direction, the tracking feature number is smaller than the threshold value; the camera direction is actively switched to serve as a main tracking source, new feature points are supplemented at the same time, and system collapse caused by local view failure is avoided.
