AI Technical Summary

Problems solved by technology

[0011] In particular, if the image display frequency is too low, images per second F i < 5, the system cannot be used advantageously because it takes too long to build the image and it is also impossible to obtain a good picture, which causes potential problems
[0012] Moreover, the display will shake, which of course is not conducive to the panorama of objects in 3D composite imaging

Embodiment Construction

[0040] Below, combine Figure 2a and2b , starting from the model of the object formed by the stream of pixels transmitted by the application module, and describing in more detail the encoding method in the form of a digital file of a three-dimensional composite image of the digital prototype of the object, starting from the digital prototype.

[0041] refer to Figure 2a , it should be noted that the cell stream is:

[0042] EEI = { I i { EI e } e = 1 e = ex } i = 1 i = ...

Abstract

A method of coding, in the form of a digital file of a three-dimensional synthesis image, a model of an object formed by a stream of image elements (FEI) in which elementary images which are subsets of image elements {EIe}e=1e=ex are discriminated (A) in the stream (FEI), each elementary image is coded (B) according to an index value (n) representative of the elementary image, the numerical values (Zk,g,i) of the 3D synthesis image are calculated (C) and these values are stored in the form of a digital file. Application to 3D display involving an interactive dialogue with a user of a graphics application.

Description

technical field [0001] The present application is concerned with displaying on-screen digital geometric data known as digital mock-ups in the form of composite images in appropriate fields, such as technical, scientific or research fields. Background technique [0002] Among the fields mentioned above, computer-aided design for fields related to the mechanical industry, carrying out manufacturing processes of special projects, remote operations in hazardous or sensitive areas, including in particular minimally invasive surgery or other operations, deserves particular mention. [0003] Applications in all these fields require very high precision and accuracy in the reconstruction of objects or parts of objects, which can be achieved in integrated imaging. [0004] For example, as shown in FIG. 1a, a screen system for displaying a digital mockup in the form of a composite image includes a client graphics application on, for example, a workstation, where the client graphics app...
