Abstract: To solve the disadvantages of the corner detector based on chord-to-point distance accumulation,low location accuracy,high detector time complexity and so on,a fast robust corner detector was proposed．This detector combines the advantages of ‘single scale’ and ‘multi-scale’．Firstly,it obtains the candidate corner under single scale,keeping the adjacent corner,and reducing following calculation greatly．Then,it calculates the eigenvalues of the candidate corners under multi-scale,eliminates false corners effectively．The experiment result shows that the detector reduces time complexity,keeps the robustness of the detector and the accuracy of corner location is also improved.

Key words: Chord-to-point distance accumulation,Fast,Corner detection,Corner location,Time complexity
