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 estimating epipolar geometry and to be performed by a processing module includes the steps of: A) choosing, in each first and third images captured by a first image capturing module, two points which are collinear with a corresponding one of a first reference object in the first image and a second reference object in the third image, such that in each second and fourth images captured by a second image capturing module, two points corresponding to the two points chosen in a respective one of the first and third images are collinear with a corresponding one of the first reference object in the second image and the second reference object in the fourth image; and B) determining first and second epipoles based on the aforementioned points.

A stereoscopic imaging method includes: acquiring a convergence disparity value, which corresponds to a screen position at which a viewer is looking, from an original disparity map corresponding to first and second images that correspond to different viewing angles; generating a disparity transformation model based on the convergence disparity value and viewer-related information; transforming the original disparity map into a transformed disparity map based on the disparity transformation model; and synthesizing the first and second images into a stereoscopic image based on the transformed disparity map.
