Provided are a tour guiding method and apparatus, an electronic device and a storage medium. The method includes receiving a video stream collected by a user in a current location area of a target scenic spot and sent by an application device; determining, based on the collected video stream and prestored three-dimensional point cloud data of the target scenic spot, an augmented-reality-based content resource package corresponding to the current location area, where the augmented-reality-based content resource package includes at least six-degrees-of-freedom attitude data of the application device; and sending the augmented-reality-based content resource package corresponding to the current location area to the application device to enable the application device to provide the augmented-reality-based content resource package corresponding to the front location area for the user.

Tour guiding method, electronic device and storage medium

A method and apparatus of generating a three-dimensional (3D) image are provided. The method of generating a 3D image involves acquiring a plurality of images of a 3D object with a camera, calculating pose information of the plurality of images based on pose data for each of the plurality of images measured by an inertial measurement unit, and generating a 3D image corresponding to the 3D object based on the pose information.

Three-dimensional image generation method and apparatus

An apparatus and corresponding method are provided to match images and include assigning depth candidate values to a pixel in a first image, and reassigning third depth candidate values to a first pixel in the first image based on first depth candidate values assigned to the first pixel and second depth candidate values assigned to a second pixel adjacent to the first pixel. The apparatus and method also include determining one of the third depth candidate values to be a depth value of the first pixel, and matching the first pixel and a third pixel in a second image corresponding to the determined depth value of the first pixel.

Image matching apparatus and method thereof

A laser alignment device with at least one movable mirror, a laser-target alignment sensor with movable mirrors and a laser alignment method are disclosed. The laser alignment device with the movable mirror comprises an image acquisition means for collecting incident lasers, a moveable mirror for reflecting the lasers to the image acquisition means and is operable to move linearly with respect to the image acquisition means, and a lens for forming an image of a target in the image acquisition means. The present disclosure achieves linear motion of the movable mirror with high accuracy in a small range, which in turn achieves fast and accurate alignment of the laser. It solves the problem of laser spots overlapping, reduces alignment time and improves shooting accuracy.
