The invention relates to an overlapped method for a virtual object in AR glasses. The method comprises that the AR glasses are fixedly arranged in a set position in a practical scene, and a practical marker with multiple scales is placed in front of the AR glasses; panoramic scanning is carried out on the practical scene to obtain a virtual scene corresponding to the practical scene; the virtual scene is introduced into a development device, and a video scene shot by the AR glasses is uploaded to the development device; after that the development device enters a debugging mode, the virtual scene and the video scene are displayed in the same interface, and virtual scales in the virtual scene are adjusted to be overlapped with shooting scales in the video scene; and the virtual object is overlapped to a target position in the virtual scene, an overlap range parameter in overlapping the virtual object in the virtual scene is obtained, and the virtual object and the overlap range parameter are sent to the AR glasses. Thus, the practical scene corresponding to the video scene can be restored highly effectively, and the virtual scene displayed by the AR glasses has a better display effect.

The invention provides a vehicle-mounted head up display device, system and augmented reality method thereof. The vehicle-mounted head up display device comprises a display device and a mirror plane, and is characterized in that the display device comprises a set of display screens arranged in an array mode, and the set of display screens comprises multiple display screens; each display screen is connected with a vehicle-mounted imaging processing device and used for receiving driving identification signals outputted by the vehicle-mounted imaging processing device, wherein the driving identification signals received by the display screens are combined into a complete driving identifier; and the driving identification signals received by each display screen are reflected by the mirror plane for one time or multiple times to vehicle wind screen glass so as to display the complete driving identifier. The embodiment of the invention enables an image projected by an HUD (head up display) on the wind screen glass to be large and long in distance.

The invention discloses a 3D material additive printing machine. A power device, a traveling device, a printing device and a screen frame device are disposed on a machine frame. Power of the traveling device is provided through the power device, and the machine frame is driven to move; the printing device comprises a scraper and a printing support; the screen frame device comprises a screen frame and a screen frame lifting device, and the screen frame is fixed to the machine frame through the screen frame lifting device; the printing support is disposed in the position, above the screen frame device, of the machine frame, and the scraper is arranged on the printing support; a printing control system comprises a distance judging device, a scraping force sensor, a processor and a position adjusting device; the processor receives a distance signal judged by the distance judging device and a scraper scraping force signal sensed by the scraping force sensor and instructs the position adjusting device to make adjustment, so that preset distance between screen cloth and a layer printing surface and the preset scraping force of the scraper are maintained; and accordingly, printing ink can uniformly permeate a silk screen and can be uniformly distributed on a to-be-printed target, repeated accurate overlaying is achieved, and the thickness of material additive manufacturing is reached.

The invention discloses a DSM automatic comparison system based on aerial photography measurement, which belongs to the technical field of aerial photography measurement. The elevation data of the two-phase aerial photos processed by the image processing module is extracted, the elevation conversion module is used to convert the elevation data of the two-phase aerial photos extracted by the elevation extraction module into a vector layer, and the layer overlay module is used for the two-phase aerial photos The vector layer of the photo is superimposed, and the comparison and labeling module is used to mark the area that has changed in the vector layer of the two-phase aerial photo. The time and manpower input for the comparison can more accurately detect the existence of illegal buildings. The comparison is more pertinent, and the effect of buildings with different areas can be screened by adjusting the value of each value.

The invention provides a method for splicing characteristic point correction partitions and is used for solving the problem of digital convergence of historical precious drawings in the prior art. The method comprises the following steps of: 2, acquiring first image data, and selecting a characteristic point group of a first area on a first image according to a preset coordinate; 4, correcting each characteristic point in the characteristic point group, and thus forming a second area; and 6, splicing the second area at a position, corresponding to the first area, on a second image. By adoption of the technical scheme of the invention, the problem of the digital convergence of various kinds of paper drawings which are accumulated over the years and include paper geologic maps with different time, different dryness and humidity and different scales can be effectively solved, the paper drawings can be accurately superposed and converged with geologic, geographic and grid vector data, and use requirements of stages such as scanning, designing, construction, running and maintenance on geologic information are met.

A manufacturing apparatus (20) has a reel-out mechanism (32), a processing mechanism (36), a label bonding mechanism (40), a reservoir mechanism (42), a peeling mechanism (44), a substrate feed mechanism (45), an attachment mechanism (46), and a base peeling mechanism (186). A cooling mechanism (122) is disposed between the attachment mechanism (46) and the base peeling mechanism (186), for cooling an attached substrate (24a), the attached substrate (24a) being made up of a glass substrate (24) and a photosensitive web (22) attached thereto, from which a protective film (30) has been peeled off, together with a heating mechanism (182) for heating a resin layer, for example a cushion layer (27), inside the cooled attached substrate (24a) to within a predetermined temperature range, which is at or below the glass transition temperature.

The video overlay device includes a first dynamic video signal storage module for storing a dynamic video signal and transmitting the dynamic video signal to a storage control module; the storage control module for controlling the real-time storage of the dynamic video signal and transmitting the dynamic video signal to a second dynamic video signal storage module; the second dynamic video signal storage module for storing the dynamic video signal and transmitting the dynamic video signal to a video overlay module; a local video signal storage module for storing a local video signal and transmitting the local video signal to a video overlay module; the video overlay module for overlaying the dynamic video signal and the local video signal and transmitting the overlaid video signal to a display module; and the display module for receiving the overlaid video signal transmitted by the video overlay module and displaying the overlaid video signal.

This invention is about a set of tableware that can be stacked into a vase when put away, and it mainly includes bowls and dishes. The tableware are put upper or lower to form a stereo vase. Each tableware will contribute to the outside wall of the external contour of the vase. The methods to make a set of tableware contain the procedure of determining the external contour of the vase, the sorts and quantity and outside walls of tableware, the positioning mode of stacking and formed tableware etc. One advantage of producing such set of tableware is that the tableware can be stacked into a complete vase which is really like a vase-a garniture in a household. Each tableware can be independently used, easily taken away or replaced. The make method is simple and precise.
