EasyAR Sense 2.0 release notes

2.0.0

2017-05-29

Starting from SDK 2.0, EasyAR has two products: EasyAR SDK and EasyAR CRS (Cloud Recognition Service). EasyAR SDK has two variants: EasyAR SDK Basic and EasyAR SDK Pro.

EasyAR SDK 2.0 Pro is a brand-new version of the SDK. In addition to all features of EasyAR SDK Basic, it includes more exciting features. EasyAR SDK Pro is a paid SDK. Details about pricing, payment methods, and other information can be found on the EasyAR website. EasyAR SDK Pro also provides a free trial. During the trial period, the number of app launches per day is limited.

EasyAR SDK Pro has these brand-new features:

  1. 3D object tracking

    Real-time recognition and tracking of common textured 3D objects in daily life.

  2. SLAM

    Monocular real-time 6DoF camera pose tracking.

  3. Screen recording

    Efficient and easy-to-use screen recording.

EasyAR CRS is a cloud image recognition service that is now open for use. Recognition images can be dynamically managed in the cloud. By using the corresponding APIs in the SDK, cloud services can recognize recognition images stored in the cloud and obtain data information associated with those images. EasyAR CRS is a paid service. Details about pricing, payment methods, and other information can be found on the EasyAR website. EasyAR CRS also provides a free trial, so related features can be tested at no cost.

EasyAR SDK 2.0 Basic is the upgraded version of EasyAR SDK 1.x. This version can be used commercially for free. All features of EasyAR 1.x can still be found in this version, and we have not added any restrictions or watermarks. EasyAR SDK 2.0 Basic has many improvements, mainly in the following areas:

  1. Workflow and API changes

    EasyAR is evolving, and the new workflow will provide more flexibility. The EasyAR one-stop solution that we are improving will also bring more flexibility to 2.0. This change is not very obvious in the Unity API, but the names of some components have changed.

  2. Brand-new programming language support

    EasyAR SDK now exports a pure C interface, giving developers more freedom. We have also added support for many programming languages, including C/C++11/traditional C++/Java for Android/Objective-C for iOS. Each language has a sample that demonstrates basic usage. We will add support for more languages in future minor releases.

  3. Cloud recognition support

    EasyAR SDK now has built-in cloud recognition support.

  4. Many improvements, bug fixes, and compatibility enhancements

    We improved QR code detection, adjusted many APIs for greater flexibility, fixed many bugs including incorrect display on some Android devices and several memory-related issues, and improved EasyAR SDK compatibility with AMD CPUs as well as third-party SDKs such as Unity3D and Google VR SDK.
