Overview

Overview

SentiSculpt is designed for software developers who want to use computer vision-based 3D object model reconstruction from images in their applications.
Object models are created automatically from sets of photos, which were captured from different angles using regular cameras.
Available as a software development kit that provides for the development of 3D object model creation systems for Microsoft Windows.

SentiSculpt technology is designed for rapid creation of 3D object models from series of 2D images. The generated models are suitable for wide range of applications, including virtual or augmented reality, video games creation, 3D printing, computer aided design, architecture etc. The object size may range from a small toy to a large building.

The SentiSculpt technology has these capabilities for 3D object model reconstruction:

Building model

 

Camera positions reconstruction

  • Converts Series of Photos into 3D Model

SentiSculpt needs series of object photos, which are made from different angles. Each photo is analyzed by the advanced computer vision algorithms, and certain features of the object are captured for the point cloud creation. See the recommendations and specifications for the photography-related details.

  • Common Camera Required

The photos for the 3D object model reconstructions can be made with an off-the-shelf camera or a smartphone. A tripod can be used for improving photography quality. The optimal model creation performance needs 2-5 megapixel camera resolution. The recommendations and specifications contain more detailed information about camera setup.

  • Automatic Images Processing

Common 3D model creation may need many hours of work by a trained designer. SentiSculpt algorithm provides simple 3D model creation workflow and does not require advanced skills, as its input is usually a folder with images. The algorithm analyzes each image, recreates the shooting angle, extracts the necessary features and adds them to the object model.

  • Advanced 3D Model Creation

The technology performs several steps of object model creation. A point cloud is created at first. A mesh (wireframe model) is generated based on the point cloud. A texture is recreated from the captured object surface and applied to the generated model, so the final model has realistic look.

  • 3D model export into widely supported formats

SentiSculpt allows to save the generated object model in widely used file formats so the model can be used by most 3D graphics and CAD applications.

SDK Contents

 

SentiSculpt SDK is designed for developers who want to use computer vision-based 3D object model reconstruction in their applications. The SDK allows rapid development of computer vision-based 3D object model reconstruction systems using functions from the SentiSculpt library for Microsoft Windows platform (see also the system requirements).

SentiSculpt SDK distribution package contains these components for Microsoft Windows (64-bit):

  • SentiSculpt installation license (1 single computer license)
  • Device manager library
  • Programming samples for C, C++ and C# languages
  • SentiSculpt SDK documentation

System Requirement

System Requirement

 

  • PC with x86-64 (64-bit) processor: 
  • SSE2 support is required. Processors that do not support
  • SSE2 cannot run the SentiSculpt algorithm. Please check if a particular processor model supports SSE2 instruction set.
  • SSSE3 support is recommended, as the SentiSculpt algorithm provides higher performance using this instruction set. Please check if a particular processor model supports SSSE3.
  • 32-bit architecture is not supported.
  • At least 1 GB of free RAM should be available for the SentiSculpt-based application. Additional RAM may be required for working with larger images and larger sets of images, as well as larger object models.
  • Microsoft Windows XP / Vista / 7 / 8 / Server 2003 / Server 2008 / Server 2008 R2 / Server 2012, 64-bit only.
  • Microsoft .NET framework 3.5 or newer (for .NET components usage).
  • Microsoft Visual Studio 2008 SP1 or newer (for application development under C/C++, C#, Visual Basic .Net)

Technical Specifications

Technical Specifications

 

  • 2 – 5 megapixel camera resolution is recommended for optimal reconstruction performance and 3D model quality. Larger resolution will slow down model creation performance, so users should consider if it is acceptable for them. Model quality can be also improved by using larger number of photos from different angles.
  • Tripod usage is highly recommended to avoid blurry images.
  • Camera settings should be adjusted before making photos of an object:
    • The auto focusing should be disabled.
    • Avoid zooming in/out between shots of the same session, constant focal length should be used. Digital zoom should be also avoided in the same session and used with care in general, as it leads to all kinds of distortions, noise and reduction in the actual image resolution. If you need more details, you can go closer to the object.
    • Flash should be disabled to avoid reflections on the object’s surface.
  • Constant lighting condition are recommended, as variations in light during the same session can lead to an inaccurate reconstruction results, or even to a failure.
  • Circular trajectory is recommended for object capture. The camera angle can change by about 15 degrees in horizontal plane for each shot, resulting in about 24 shots of the object. Images must overlap by approximately 2/3. Same features of the object should be visible on at least 3 adjacent photos.
  • Object model reconstruction may be problematic in these cases:
    • objects with shiny surfaces;
    • partially or fully transparent objects (glass, windows, water);
    • periodically textured objects (like chess board);
    • objects without any texture (plain painted walls).

 

Licensing Model

Licensing Model

 

The following licensing model is intended for end-userproduct developers. Integrators who want to develop and sell a SentiSculpt-based development tool (with API, programming possibilities, programming samples, etc.), must obtain permission from Neurotechnology and sign a special VAR agreement.

Product Development

An integrator should obtain a SentiSculpt SDK (EUR 859) to develop a product based on SentiSculpt technology. The SDK needs to be purchased just once and may be used by all the developers within the integrator’s company.
SentiSculpt SDK includes SentiSculpt component. A license for an individual SentiSculpt component is required for each CPU that runs the component (a processor can have any number of cores).
One single computer license for the SentiSculpt component is included with SentiSculpt SDK.
Components are copy-protected – a license is required for a component to run. License activation options are listed below on this page.
Additional component licenses may be obtained by SentiSculpt SDK customers as required by their development process.

Product Deployment

To deploy a product developed with SentiSculpt SDK, an integrator need obtain only the additional licenses required for the SentiSculpt components that will run on each CPU of their customer’s computers. The available license types for product deployment are the same as for product development.
Each SentiSculpt component running on a computer belonging to the integrator’s customer requires a license. License activation options are listed below on this page.
Prices for the SentiSculpt SDK and additional SentiSculpt component licenses can be found here.

Licensing Agreement

The Licensing Agreement contains all licensing terms and conditions.
Note that you unambiguously accept this agreement by placing an order using Neurotechnology online ordering service or by email or other means of communications. Please read the agreement before making an order.

Single computer licenses

A single computer license allows the installation and running of a SentiSculpt component installation on one CPU (a processor can have any number of cores). Neurotechnology provides a way to renew the license if the computer undergoes changes due to technical maintenance.
Each single computer license requires activation for a SentiSculpt component to run. The available activation options are listed below on this page.
Additional single computer licenses for SentiSculpt components may be obtained at any time by SentiSculpt SDK customers.

License activation options

Single computer licenses are supplied in three ways:
Serial numbers are used to activate licenses for SentiSculpt components. The activation is done via the Internet or by email. After activation the network connection is not required for single computer license usage.
Note: activation by serial number is not suitable for virtual environments.
Internet activation. A special license file is stored on a computer; the license file allows to run SentiSculpt components on that computer after checking the license over the Internet.Internet connection should be available periodically for a short amount of time. A single computer license can be transferred to another computer by moving the license file there and waiting until the previous activation expires.
Licenses may be stored in a volume license manager dongle. License activation using volume license manager may be performed without connection to the Internet and is suitable for virtual environments.

Volume license manager

Volume license manager is used on site by integrators or end users to manage licenses for SentiSculpt components. It consists of license management software and a dongle, used to store the purchased licenses. An integrator or an end-user may use the volume license manager in the following ways:

  • Activating single computer licenses – An installation license for a SentiSculpt component will be activated for use on a particular computer. The number of available licenses in the license manager will be decreased by the number of activated licenses.
  • Managing single computer via a LAN or the Internet – The license manager allows the management of installation licenses for SentiSculpt components across multiple computers in a LAN or over the Internet. The number of managed licenses is limited by the number of licenses in the license manager. No license activation is required and the license quantity is not decreased. Once issued, the license is assigned to a specific computer on the network.
  • Using license manager as a dongle – A volume license manager containing at least one license for a SentiSculpt component may be used as a dongle, allowing the SentiSculpt component to run on the particular computer where the dongle is attached.
    Additional SentiSculpt component licenses for the license manager may be purchased at any time. Neurotechnology will generate an update code and send it to you. Simply enter the code into the license manager to add the purchased licenses.

Enterprise license

The SentiSculpt enterprise license allows an unlimited use of SentiSculpt components in end-user products for a specific territory, market segment or project. Specific restrictions would be included in the licensing agreement.
The enterprise license price depends on the application size and the number of potential users of the application within the designated territory, market segment or project.
