The invention relates to a robust tracking method of target in an airport monitoring video, which combines singular value decomposition (SVD) and particle filtering target tracking technology. The method comprises the following steps: step 100: initiating, generating particle swarm containing N particles, carrying out SVD for the tracked target, and establishing template model; step 200: forecasting state by forecasting position of the target in current frame based on position of the target in a prior frame; step 300: updating particle weight, carrying out SVD for candidate image area, establishing feature vector, and comparing similarity of the candidate area and the template by using least squares criterion to be weight of the particle; step 400: re-sampling particle, keeping particles with larger weight, discarding particles with smaller weight, enabling particles with larger weight to derive new particles to keep total number N of particles unchanged, and transferring new particles and the next frame of image to step 200 for circulation operation; and step 500: outputting result, and weighting all particles and weight of all particles to obtain position of the target in current frame. The invention solves problems of complicated scene, frequent illumination change, serious interference caused by background analogue and the like of existing airport monitoring video, and meets requirements of robustness and accuracy in monitoring and tracking process.
