HiLens Framework_C++

The HiLens Framework Software Development Kit (SDK) is a C++ development package running on HiLens Kit cameras. Users can use the HiLens SDKs to develop C++ skills and run them on HiLens Kit cameras.

HiLens Framework Introduction

The HiLens Framework encapsulates bottom-layer APIs to implement common management functions, enabling developers to easily develop skills and cultivate the AI ecosystems on the HiLens management console.

Figure 1 shows the layered structure of HiLens Framework. HiLens Framework encapsulates the underlying multimedia processing libraries (cameras/microphone driver module Media_mini), the image processing library (DVPP) related to D chips, and the model management library (ModelManager). Developers can also use the familiar visual processing library OpenCV. HiLens Framework provides the modules in Table 1 for developers, such as human figure detection and fatigue driving detection.
