The invention relates to the technical field of augmented reality, and particularly provides a high-speed VSLAM augmented reality helmet self-positioning method based on an on-orbit special-cause environment, and the method comprises the steps: collecting image information in the on-orbit special-cause environment through a visual sensor on augmented reality equipment; calculating the pose of the visual sensor corresponding to the current frame image in real time based on the previous frame image; wherein when the frame number of the current frame image is the end frame in the current calculation period, the pose of the visual sensor corresponding to the image in the current calculation period is locally optimized; and when loopback is detected, performing global optimization on the pose of the visual sensor corresponding to the image between the loopback frame and the current frame. According to the technical scheme provided by the invention, the problem of augmented reality helmet positioning in an on-orbit
