The present invention relates to terahertz sensors and photogrammetry, and more specifically, this invention relates to augmented reality (AR) applications of terahertz sensors and photogrammetry.
Terahertz waves (e.g. T-rays, T-waves, T-light, T-lux, or THz) are electromagnetic waves within the International Telecommunication Union (ITU) designated band of frequencies. Terahertz wave frequencies range from 0.3 to 3 terahertz (1 THz=1012 Hz). Wavelengths of radiation in the terahertz band range from 0.1 mm to 1 mm (100 μm). Terahertz waves may penetrate various materials. Terahertz waves are non-ionizing and harmless to living tissue, DNA, etc. Measurements of the terahertz beams may be used for material characterization, layer inspection, alternative x-ray techniques, security screening, etc. Terahertz waves may be capable of producing high resolution images of solid objects.
Photogrammetry is the science of making measurements from photographs. Multiple photographs may be used to estimate three-dimensional (3D) coordinates of surface points of an object in an image. The output of photogrammetry is conventionally a map, drawing, measurement, and/or 3D model of the subject of the photographs. Photogrammetry may be used to create maps, in visual special effects, in various engineering applications, for vehicle accident investigations, etc.

Consumers within the clothing retail industry are demanding more technology designed to improve their shopping experience. Augmented reality technology may be used to supplement real world environments, including clothing stores. Many companies are taking advantage of consumer demand for AR-assisted clothing shopping by incorporating 3D-modeled clothing and/or humans into online shopping applications. However, creating individual 3D models of clothing using computer-aided design (CAD) software is expensive and/or time consuming. The high cost of entry prevents smaller retailers and/or individuals from taking advantage of AR technology.
In various embodiments disclosed herein, an apparatus and method for creating 3D models of clothing, including various characteristics of the clothing, are described. Such characteristics may include the shape, the fabric types, the thickness, etc. of the clothing. Photogrammetry techniques and/or terahertz sensors may be used to characterize the clothing and/or provide a 3D model of the clothing.
As shown, the apparatus 300 comprises a frame 302 and a plurality of terahertz sensors 304 coupled to the frame. The plurality of terahertz sensors may be coupled to the frame in any manner known in the art.

Now referring to
Each of the steps of the method 500 may be performed by any suitable component of the operating environment. For example, in various embodiments, the method 500 may be partially or entirely performed by a computer, or some other device having one or more processors therein. The processor, e.g., processing circuit(s), chip(s), and/or module(s) implemented in hardware and/or software, and preferably having at least one hardware component may be utilized in any device to perform one or more steps of the method 500. Illustrative processors include, but are not limited to, a central processing unit (CPU), an application specific integrated circuit (ASIC), a field programmable gate array (FPGA), etc., combinations thereof, or any other suitable computing device known in the art.
As shown in
The imaging data may be received in any manner known in the art. In one approach where operation 502 and/or method 500 is performed by an apparatus such as one of the apparatuses shown in
Operation 504 includes processing the imaging data into a three-dimensional model of the article of clothing. Operation 504 may comprise processing imaging data from at least one terahertz sensor from various vantage points, and optionally imaging data from at least one image capturing device. In one approach, imaging data from one or more terahertz sensors may be processed into a three-dimensional model of the article of clothing. In a preferred approach, operation 504 includes processing imaging data from at least one terahertz sensor and at least one image capturing device. The imaging data from at least one image capturing device may be from various vantage points. The imaging data from the sensor(s), and from the image capturing device(s) if present, may be merged to generate a 3D model of the article of clothing.
In one approach, operation 504 may include processing the imaging data using any photogrammetry software and/or combination of image processing techniques known in the art.
In one approach, the imaging data gathered via an image capturing device may be used to generate various overlays usable with the 3D model of the article of clothing. The overlays may include different patterns, textures, styles, shapes, etc. which are interchangeable within the 3D and/or overlaying the 3D model. In one approach, the overlays may be different than the actual appearance of the modeled article of clothing.
Operation 506 includes outputting the model. In one approach, the output is a 3D model of the processed data. The model may be output in any form known in the art. In various approaches, the model may be “blank slate” which one of ordinary skill in the art may use for various processes.
Various embodiments include using the 3D model created by method 500. A preferred embodiment includes using the 3D model in AR clothing shopping applications. For example, the model may be used for allowing a user to try on clothing they wish to buy. The user may be located in a store, at home, or any other location. In another example, the various embodiments described herein may be used to generate 3D models of a user's wardrobe such that the user may try on clothes which they already own in order to choose an outfit, to determine if an outfit still fits properly, etc.
The various embodiments describe herein disclose cost-effective and efficient methods and apparatuses for generating and using 3D models of articles of clothing. The ability to more economically create 3D models of clothing may allow smaller retailers to offer the services which are similar to services offered by larger clothing retailers. These services in turn result in increased profits by engaging consumers who avoid shopping in person and/or fitting rooms. AR assisted shopping and 3D models may also reduce returns, especially for online shoppers who conventionally buy clothing without the ability to try on the articles of clothing beforehand.
