An image processing system for converting 2D images into 3D model includes a selecting model, an asset importing module, a converting module and a model generating module. The selecting model receives a category selecting instruction to select an object category and receives a template selecting instruction to select an object template corresponding to the object category. The asset importing module receives a plurality of 2D views of a target object in different view angles. The converting module projects the 2D views to the object template to generate a projected image. The model generating module amends the projected image to generate a 3D model.
