Abstract: A structured-light three-dimensional (3D) scanning system includes a projector that emits a projected light with a predetermined pattern onto an object; an image capture device that generates a captured image according to a reflected light reflected from the object, the predetermined pattern of the projected light being distorted due to 3D shape of the object, thereby resulting in a distorted pattern; a depth decoder that converts the distorted pattern into a depth map representing the 3D shape of the object; and a depth fusion device that generates a fused depth map according to at least two different depth maps associated with the object.

Abstract: The device includes a projecting device, an image sensor and a computing circuit. The projecting device provides a light beam having a predetermined pattern that is projected onto an object. The image sensor receives the light beam reflected from the object to generate an image. The computing circuit compares the image with a first ground-truth image and a ground-truth image to generate a first depth value and a second depth value respectively. The first and second depth values are combined to generate a depth result.

Abstract: A retractable flagpole assembly includes a retractable flagpole, a top pivot holder rotatably capped on the top rod of the retractable flagpole and provided with a hanging lug for securing an inner top end of a flag, an end block spaced below the lower pivot holder and provided with a hanging lug for securing an inner bottom end of the flag, a link coupled between the top pivot holder and the end block, and a lower pivot holder rotatably sleeved onto the retractable flagpole and axially movable along the link and lockable to the end block.

Abstract: A flag pole device includes a pole, an upper rotary barrel and a lower rotary barrel rotatably mounted on the pole for securing a flag, and a connection rod connected between the upper rotary barrel and the lower rotary barrel. The upper rotary barrel and the lower rotary barrel each have a side column at the periphery, which has a through hole for receiving the connection rod. The connection rod has opposing flat top and bottom end portions disposed in the same plane and respectively inserted through a flat bottom hole portion of the through hole of the upper rotary barrel and a flat top hole portion of the through hole of the lower rotary barrel and positioned in a respective crossed hole portion and stopped at a respective step in the side column of the upper rotary barrel and the side column of the lower rotary barrel, assuring synchronous rotation of the upper rotary barrel and the lower rotary barrel and avoiding tangling of the flag on the pole.
