In order to solve the problem of processing efficiency of traditional image interpolation methods,a spatial res-olution detection method of remote sensing mapping image based on wavelet bicubic interpolation was proposed.Wavelet bicubic interpolation is used to segment remote sensing mapping image into spatial units.The image filtering coefficient ma-trix is constructed based on the principle of Kosambi-Karhunen-Loève theorem.Adopting a heterogeneous parallel system,high-density value calculation is carried out under the CUDA architecture,achieving rapid detection of spatial resolution in remote sensing surveying and mapping images.The experimental results show that the proposed method can preserve more details and texture information when converting images.Under different mapping ratios,resolution detection can be comple-ted within 2.5 s,with relatively high horizontal and vertical resolution results,suitable for human eye observation and prac-tical application effects.
