The present invention provides an automatic container loading and unloading apparatus and method. The apparatus comprises: a data acquisition module, used for scanning a container truck panel to obtain laser point cloud data; a data preprocessing module, used for segmenting a laser point cloud on a surface of the container truck panel from the laser point cloud data; a key point extraction module, used for performing edge extraction on the laser point cloud on the surface of the container truck panel to obtain discrete points on edges of the keel of the container truck panel; and a straight line fitting module, used for performing random sample consensus straight line fitting on the discrete points on the edges of the keel of the container truck panel to obtain spatial straight lines of the edges of the keel of the truck panel. The automatic container loading and unloading apparatus and method provided by the present invention using spatial straight lines on the edges of the keel of the container truck panel for computing processing, thereby achieving stronger robustness and higher accuracy, so that a container is loaded onto the container truck panel with higher precision and lower calculation amount.

A three-dimensional model generation method includes: detecting a first line from each of a plurality of images of a target area shot to detect a plurality of first lines, the plurality of images being shot from a plurality of viewpoints; excluding, from the plurality of first lines detected, a second line that reaches an edge of an image among the plurality of images; and generating a line segment model which is a three-dimensional model of the target area represented by lines, using a plurality of line segments which are the plurality of first lines from which the second line is excluded.

Embodiments include systems and methods for generating 2D and 3D layouts from a physical 3D space captured by a capturing device, the layouts having an identical scale to the physical 3D space, and estimating measurements of the physical 3D space from the layouts. The capturing device captures a point cloud or 3D mesh of the physical 3D space, from which one or more planes are identified. These one or more planes can then be used to create a virtual 3D reconstruction of the captured 3D space. In other embodiments, one plane may be identified as a floor plane, and features from the point cloud or 3D mesh that are above the floor plane may be projected onto the floor plane to create a top down view and 2D layout. Other embodiments are described.

Manufacturing of a shoe is enhanced by creating 3-D models of shoe parts. For example, a laser beam may be projected onto a shoe-part surface, such that a projected laser line appears on the shoe part. An image of the projected laser line may be analyzed to determine coordinate information, which may be converted into geometric coordinate values usable to create a 3-D model of the shoe part. Once a 3-D model is known and is converted to a coordinate system recognized by shoe-manufacturing tools, certain manufacturing steps may be automated.

A communication system captures writing surface content in a physical space for transmittal to remote client devices participating in a communication session. During a communication session with one or more remote client devices, a communication system captures image data and depth data describing objects in a physical space of the communication system. Based on the captured data, the communication system identifies a writing surface in the physical space and captures content on the writing surface. The communication system may also identify objects occluding content on the writing surface based on the captured data and may modify image data to make an object occluding the content at least partially transparent. The communication system transmits the content to at least one of the remote client devices participating in the communication session.
