Intel® RealSense™ SDK Code Samples

This set of code samples was created to be used during the Brazilian Intel RealSense Hands-on Labs to make it easier for the participants to understand how to use the Intel® RealSense™ SDK.

This article is in the Product Showcase section for our sponsors at CodeProject. These articles are intended to provide you with information on products and services that we consider useful and of value to developers.

Abstract

This set of code samples was created to be used during the Brazilian Intel RealSense Hands-on Labs to make it easier for the participants to understand how to use the Intel® RealSense™ SDK. The 12 samples use the C# SDK wrapper and provide simple, console-based apps that print the information available from the RealSense modalities including face and hand tracking and speech recognition. Also, there are two WPF apps showing how to display the camera streams and how to achieve background subtraction .

Introduction

As part of preparation for the Hands-On Labs Brazil, we created 12 code samples with instructions to show how to leverage Intel RealSense voice and camera capabilities with simple examples. The code is commented (in English) and can be freely shared with the worldwide developers’ community.

The samples were implemented using C# and are basically simple console applications that show how to use the RealSense SDK functionalities. The code has been tested with the Intel RealSense SDK R2 (RSSDK).

We hope you enjoy our contribution and if you have any questions or need help, please use the comments section below.

Pre-Requisites to Run the Samples

Important Intel RealSense Documentation Links

Available Samples

Camera Calibration Library

Camera Calibration is a library project that receives a device and a modality and makes the proper calibration to improve the quality of the camera recognition for that specific mode, for example hand tracking.

Reference Links:

Device

The Device sample makes device enumeration possible. Select a device and get the available streams and set device configurations. Note: this sample uses the Camera Calibration Library to configure the devices.

Reference Links:

Emotion

The Emotion sample lists emotions using SenseManager with a procedural implementation. This sample finds all the emotion data and prints each one along with its intensity value.

Reference Links:

Emotion with Callback

The Emotion with Callback sample has the same functionality as the Emotion sample, but with a different implementation. It shows how to use handlers in the RSSDK to get module data. It uses the Emotion module, but can be implementated with other modules.

Reference Links:

Face

Face is a sample that implements some of the various functionalities of the Face module. It uses the PXCMFaceData object and processes information separately as listed in the functionalities below:

Reference Links:

Face Recognition

The Face Recognition sample detects a face and checks if the user is already registered. When the program detects a face that is not registered, the user can press the space bar to register their face in the database (in memory).. After registration, the sample prints the unique identifier of the recognized face.

Reference Links:

Hands

The Hands sample tracks hands, fingers and gestures. The sample prints how many hands are detected and their positions (image and world), body sides, joints and detected gestures.

Reference Links:

Object Tracking

The Object Tracking sample detects a 2D object using the Intel RealSense SDK. It uses JPEG/PNG markers, and tracks X, Y, and Z positions as the object is tracked by the camera. Note: This sample requires that the camera is calibrated with a specific tag.

Reference Links:

Segmentation

Image 1

The Segmentation sample uses the WPF structure to display the camera stream on a WPF form and uses the Segmentation feature to remove the image background.

Reference Links:

Speech Recognition

The Speech Recognition sample shows how to use both Speech Recognition modes: DICTATION or COMMAND. In dictation mode, it recognizes all words that users are saying and prints them on the screen. In Command mode, the program sets a standard dictionary and when the user says one of added commands, it prints it on the screen.

Speech Synthesis

The Speech Synthesis sample is an implementation of the text-to-speech capability of the Intel RealSense SDK. When a sentence is made available in the profile, it converts the sentence to audio and plays it.

Reference Links:

Streams

IR stream view (notice the effect from the outside lighting in the background.)

Image 2

The Streams samples uses the RSSDK to display the Creative Camera streams (Color, Depth and Infrared) into a WPF form. The sample selects a stream by its type and shows a window with the selected camera stream, updating the image frame-by-frame in the selected FPS configuration.
