The invention discloses a large-range asphalt pavement quality rapid assessment method and system based on high-resolution remote sensing. The method comprises the following steps: acquiring a high-resolution multispectral image and a panchromatic image of a pavement area of a road network area to be assessed; generating superpixels of the road surface area based on the high-resolution multispectral image and the panchromatic image of the road surface area; removing super-pixels of a non-asphalt pavement from the super-pixels of the pavement area to obtain asphalt pavement super-pixels of the pavement area; calculating a brightness index, a texture index, a structure index and a spectrum index of each superpixel of the asphalt pavement based on the superpixels of the asphalt pavement; according to the brightness index, the texture index, the structure index and the spectrum index obtained through calculation, a quality remote sensing evaluation index corresponding to each superpixel of the asphalt pavement is
