The invention discloses a high-altitude throwing traceability detection method, and relates to a traceability detection method. The invention aims to solve the problem that a high-altitude parabolic object in a video cannot be automatically found and correspondingly processed at present. The method comprises the following specific steps: establishing a tracker linked list; carrying out foreground segmentation on the video frame to obtain a binary image, then carrying out corresponding filtering processing and morphological operation, and carrying out contour detection on the binary image; after the contour of the current frame is extracted, judging whether an existing target exists in the tracker linked list or not for each contour; when the tracking target accords with the motion law of the parabolic object, the confidence level is increased; traversing the tracer chain table, and removing the tracer of which the target disappears; if the target tracked by the tracker is a parabolic object, parabolic object
