In response to the deficiencies and limitations of the existing engineering project presentation methods,We propose a new approach based on the open-source software Blender.Taking a waterway project as an example,we use key techniques such as aerial photography and video preprocessing,camera trajectory reconstruction,3D building information modeling(BIM)and animation creation,as well as synthesis and output.This method inserts 3D BIM/animation into aerial photos/videos and achieves the fusion of the them in multiple aspects such as perspective,material,and light-shadow through virtual cameras and rendering.This method retains the advantages of low cost,high definition,and high fidelity of aerial photos/videos,and enables the display of obstructed objects such as underwater waterway and non-existent structures such as revetment,mixer station and their construction processes through BIM/animations.With its low learning and implementation cost,this method holds strong potential for widespread adoption and can be applied in engineering project bidding,scheme evaluations,and external presentation.
