Advanced.h
ApplicationConfig.h
Context.h	Context is a management class that describes the runtime of the SDK and is responsible for resource allocation and release of the SDK. Context has the ability to manage multiple devices. It is responsible for enumerating devices, monitoring device callbacks, and enabling multi-device synchronization
Device.h	Device-related functions, including operations such as obtaining and creating a device, setting and obtaining device property, and obtaining sensors
Error.h	Functions for handling errors, mainly used for obtaining error messages
Filter.h	The processing unit of the SDK can perform point cloud generation, format conversion and other functions
Frame.h	Frame related function is mainly used to obtain frame data and frame information
MultipleDevices.h	This file contains the multiple devices related API witch is used to control the synchronization between multiple devices and the synchronization between different sensor within single device
ObTypes.h	Provide structs commonly used in the SDK, enumerating constant definitions
Pipeline.h	The SDK's advanced API can quickly implement functions such as switching streaming, frame synchronization, software filtering, etc., suitable for applications, and the algorithm focuses on rgbd data stream scenarios. If you are on real-time or need to handle synchronization separately, align the scene. Please use the interface of Device's Lower API
Property.h	Control command property list maintenance
RecordPlayback.h
Sensor.h	Defines types related to sensors, used for obtaining stream configurations, opening and closing streams, and setting and getting sensor properties
StreamProfile.h	The stream profile related type is used to get information such as the width, height, frame rate, and format of the stream
TypeHelper.h
Utils.h
Version.h	Functions for retrieving the SDK version number information
hpp
ApplicationConfig.hpp
Context.hpp	The SDK context class, which serves as the entry point to the underlying SDK. It is used to query device lists, handle device callbacks, and set the log level
Device.hpp	Device related types, including operations such as getting and creating a device, setting and obtaining device attributes, and obtaining sensors
Error.hpp	This file defines the Error class, which describes abnormal errors within the SDK. Detailed information about the exception can be obtained through this class
Filter.hpp	This file contains the Filter class, which is the processing unit of the SDK that can perform point cloud generation, format conversion, and other functions
Frame.hpp	Frame related type, which is mainly used to obtain frame data and frame information
Pipeline.hpp	The SDK's advanced API type can quickly implement switching streaming and frame synchronization operations
RecordPlayback.hpp	Record and playback device-related types, including interfaces to create recording and playback devices, record and playback streaming data, etc
Sensor.hpp	Defines types related to sensors, which are used to obtain stream configurations, open and close streams, and set and get sensor properties
StreamProfile.hpp	The stream profile related type is used to get information such as the width, height, frame rate, and format of the stream
TypeHelper.hpp
Types.hpp
Utils.hpp	The SDK utils class
Version.hpp	Provides functions to retrieve version information of the SDK
ObSensor.h	This file serves as the C entrance for the SDK library. It includes all necessary header files for SDK usage
ObSensor.hpp	This is the main entry point for the SDK C++ library. It includes all necessary header files for using the library
