The invention discloses a large-scale target high-speed plotting method based on a GPU, and relates to a dotted military standard symbol drawing technology based on the GPU in the field of automatic command system military plotting. A CPU is used for transmitting attribute data of large-scale targets to the GPU, and on the basis of the parallel computing ability of the GPU, attribute information of each target is directly converted into corresponding military standard symbol drawing by means of a vertex shader and a fragment shader. The GPU also has the ability suitable for large-scale target real-time high-speed plotting and the ability of supporting at least a thousand of military standard symbol types, and the method has the advantages that military standard symbol type expansion is easy and drawing based on CPU keeps attractive. The method is particularly suitable for large-scale real-time dynamic target high-speed plotting application in computer situation plotting.
