AI Technical Summary

Benefits of technology

The patent describes a system that can scan the outer surface of a physical object and create a 3D model of it. The system includes a scanner that can capture data about the object's surface, and a processor that can use that data to create a 3D model of the object. The system also includes a display that can show the 3D model on the physical object. The system can also have an input device that can trace over the object's surface and add or modify the 3D model based on the pressure applied by the input device. This allows for a more accurate and precise model of the object.

Problems solved by technology

However, physically shaping the physical model is time consuming and oftentimes not easily reversible as the physical model may need to be patched in order to reverse a change made to the model.

Embodiment Construction

[0019]FIG. 1 shows a three-dimensional (3D) scanner 102 scanning a physical object 101. The 3D scanner 102 may be any device configured to scan the physical object 101 or an outer surface thereof for generating a three-dimensional model of the physical object 101. The 3D scanner 102 may be a non-contact or a contact scanner. Further, the 3D scanner 102 may be an active scanner or a non-active scanner. The 3D scanner 102 may use any technique for scanning the object, such as time-of-flight (ToF) or triangulation.

[0020]The 3D scanner 102 may be a ToF 3D laser scanner. The 3D scanner 102 may be an active scanner that uses laser light to probe the physical object 101. The 3D scanner 102 may be a stereoscopic scanner. The 3D scanner 102 may include a ToF laser range finder. The laser range finder may identify a distance between the 3D scanner 102 and the surface of the physical object 101 based on the timing of a round-trip time of a pulse of light emitted by the 3D scanner 102. The 3D s...

Abstract

A method and system for three-dimensional (3D) surface sketching are provided. A 3D scanner scans an outer surface of a physical object and outputs data representative of the outer surface. A processor generates, based on the received data, a 3D model of the object and outputs a 3D rendering of the object. A display displays the 3D rendering of the object. An input device physically traces over a portion of the outer surface of the object and a tracking device tracks a positioning of the input device as the input device physically traces over the portion of the outer surface of the object. The processor receives data representative of at least one spatial position of the input device, augments the 3D rendering of the object based at least in part on the data and outputs the augmented 3D rendering to the display.

Description

BACKGROUNDTechnical Field[0001]This application is directed to generating three-dimensional (3D) rendering of a physical object and annotating and refining the 3D rendering by physically tracing an input device over the physical object. This application is also directed to distance measurement of a curve traced by the input device.Description of the Related Art[0002]In many industries, including the automotive industry, physical models, such as clay models, are used to model automobile designs and physically illustrate design features of an automobile. Refining and augmenting a physical model is an important task in designing cars as well as other industrial or consumer products. During the industrial design process, designer and 3D modelers shape the physical model with tools and tape-mark changes to the physical model. However, physically shaping the physical model is time consuming and oftentimes not easily reversible as the physical model may need to be patched in order to rever...
