A hyperspectral image corner detection method and system. The method comprises the following steps: step A, constructing a weighted correlation function about a certain point p 0 in a hyperspectral image f(x, y, z) and a point p 1 on a neighbourhood thereof (A); step B, constructing a corner response function according to the weighted correlation function (B); step C, calculating a Harris corner response value of the certain point p 0 in the hyperspectral image f(x, y, z) and Harris corner response values of all points on the neighbourhood thereof according to the corner response function (C); and step D, if the Harris corner response value of the certain point p 0 in the hyperspectral image f(x, y, z) is greater than the Harris corner response values of all the points on the neighbourhood thereof, determining the point p 0 to be a Harris corner of the hyperspectral image f(x, y, z) (D). The detection method can acquire key information about a hyperspectral image, thereby being capable of better analyzing the hyperspectral image and improving the pattern recognition effect of the hyperspectral image.
