Assembly instruction system includes at least one depth camera, database, processor, and display. Depth camera captures first object image. Database stores multiple known object images and assembly tree. Processor compares first object image with known object images separately to recognize first object corresponding to first object image and a three-dimensional position and orientation of first object, and obtains second object (or some other multiple objects) corresponding to first object according to captured image and assembly tree. Processor generates at least one virtual arrow according to three-dimensional position and orientation. Display displays augmented reality image having at least one virtual arrow added on first object image and second object (or some other multiple objects) image(s). Virtual arrow indicates a moving direction for assembling first object and second object (or some other multiple objects). The above process is repeatedly performed until the whole device is assembled.

A method for analyzing and searching 3D models includes steps of obtaining data global features and data local features of data images by globally analyzing and locally analyzing data images of 3D models respectively; obtaining searching global features and searching local features by globally analyzing and locally analyzing searching images respectively; obtaining corresponding data global features and corresponding data local features based on the search global features and the searching local feature; and obtaining corresponding data images based on the corresponding data global features and the corresponding data local features.
