Real-time judgment method and device for visual tracking accuracy

The invention provides a real-time judgment method and device for visual tracking accuracy, and the method comprises the steps: obtaining an image Ii obtained through a visual tracking algorithm, and calculating the definition of the image Ii; acquiring the image brightness of the image Ii; obtaining the signal-to-noise ratio and clutter intensity of the image Ii, and determining the global target saliency of the image Ii; identifying a tracking target in the image Ii, obtaining the area and the rotation angle of the tracking target, and calculating the deformation degree of the tracking target; determining the position change degree of the tracking target; and determining the confidence of the tracking target identified by the visual tracking algorithm in an information fusion mode. According to the method, on the premise that the actual position and the scale of the target are unknown, the confidence coefficient of the accuracy of the tracking algorithm can be obtained through online real-time judgment of t
