The present application discloses a method and device of labeling laser point cloud. The method comprises: receiving data of a laser point cloud; constructing a 3D scene and establishing a 3D coordinate system corresponding to the 3D scene; converting a coordinate of each laser point in the laser point cloud into a 3D coordinate in the 3D coordinate system; mapping laser points included in the laser point cloud into the 3D scene respectively according to the 3D coordinate of the laser points; labeling the laser points in the 3D scene.

A redundant tracking system comprising multiple redundant tracking sub-systems, enabling seamless transitions between such tracking sub-systems, provides a solution to this problem by merging multiple tracking approaches into a single tracking system. This system is able to combine tracking objects with six degrees of freedom (6DoF) and 3DoF through combining and transitioning between multiple tracking systems based on the availability of tracking indicia tracked by the tracking systems. Thus, as the indicia tracked by any one tracking system becomes unavailable, the redundant tracking system seamlessly switches between tracking in 6DoF and 3DoF thereby providing the user with an uninterrupted experience.

This disclosure relates to managing data by an agent located within a mining operation. The data is stored as voxel data on a voxel net server. The server processes user input from a user controlling the agent within the mining operation and receives from the agent a request for voxel data associated with one or more voxels. The one or more voxels are a subset of voxels stored on the voxel net server and each of the one or more voxels is identified based on connections with voxels of previous requests. The server then queries a database representing the voxel net for the one or more voxels to retrieve associated voxel data based on the connections and returns the voxel data to the agent. Finally, the voxel data is displayed on a user device to the user.

An image processing apparatus, an image display system, an image processing method, and a program by which it is possible to display an optimum three dimensional image when display is switched from a two dimensional tomographic image to a three dimensional image are provided. The processor (14) outputs a tomographic image display signal representing a two dimensional tomographic image included in a first tomographic image group based on first imaging data obtained by imaging a subject, extracts a second tomographic image group having a smaller interval between tomographic images than the first tomographic image group, on the basis of second imaging data acquired in imaging corresponding to the imaging for acquiring the first imaging data, if a display switching signal indicating switching from display of the two dimensional tomographic image to display of a three dimensional image is acquired, and outputs a three dimensional image display signal representing a three dimensional image generated on the basis of the extracted second tomographic image group.

Some embodiments provide a navigation application with a novel declutter navigation mode. In some embodiments, the navigation application has a declutter control that when selected, directs the navigation application to simplify a navigation presentation by removing or de-emphasizing non-essential items that are displayed in the navigation presentation. In some embodiments, the declutter control is a mode-selecting control that allows the navigation presentation to toggle between normal first navigation presentation and a simplified second navigation presentation, which below is also referred to as a decluttered navigation presentation. During normal mode operation, the navigation presentation of some embodiments provides (1) a representation of the navigated route, (2) representations of the roads along the navigated route, (3) representation of major and minor roads that intersect or are near the navigated route, and (4) representations of buildings and other objects in the navigated scene. However, in the declutter mode, the navigation presentation of some embodiments provides a representation of the navigated route, while providing a de-emphasized presentation of the roads that intersect the navigated route or are near the navigated route. In some embodiments, the presentation shows the major roads that are not on the route with more emphasis than minor roads not on the route. Also, in some embodiments, the presentation fades out the minor roads not on the route more quickly than fading out the major roads not on the route.

Embodiments of the present disclosure relate to a three-dimensional reconstruction method and apparatus for a material pile, an electronic device, and a computer-readable medium. The method may include: acquiring, in response to an instruction for controlling an excavator body of an excavator to rotate to transport materials being detected, a sequence of depth images of an excavated material pile collected by a binocular camera provided on a side of the excavator; and performing three-dimensional reconstruction based on the sequence of depth images of the material pile, to generate a three-dimensional model of the material pile.

Provided is a virtual tourism method which includes: detecting, by a virtual tourism client device, a change of a viewing direction of a user in real time, generating viewing direction information of the user according to the change of the viewing direction, wherein the viewing direction change is a change of a current viewing direction of the user with respect to a reference viewing direction; and obtaining, a part of video image data corresponding to the current viewing direction of the user from stored panoramic video image data according to the viewing direction information of the user and playing the part of the video image data.

Systems and methods for visualizing navigation of a medical device with respect to a target using a live fluoroscopic view. The methods include displaying, in a screen, a three-dimensional (3D) view of a 3D model of a target from the perspective of a medical device tip. The methods also include displaying, in the screen, a live two-dimensional (2D) fluoroscopic view showing a medical device, and displaying a target mark, which corresponds to the 3D model of the target, overlaid on the live 2D fluoroscopic view. The methods may include determining whether the medical device tip is aligned with the target, displaying the target mark in a first color if the medical device tip is aligned with the target, and displaying the target mark in second color different from the first color if the medical device tip is not aligned with the target.
