When the RealSense stops connecting

The RealSense D435 RGBD camera is generally very robust and reliable. It can however fail to connect and display the image and depth frames. When this happens, hardware notification errors appear in the realsense-viewer software as shown below. Usually this is caused by a connection issue, such as trying to use USB 2 with the RealSense,…Read more When the RealSense stops connecting

Integrating the Intel RealSense D435 with ROS

The Intel RealSense D435 is the latest RGBD camera available from Intel,  and is an upgrade from the Intel R200 camera already discussed in a previous post. The D435 is a stereo depth camera that is designed to work both indoors and outdoors. The 3D reconstruction is constructed using active Infrared (IR) stereo. Setting up the…Read more Integrating the Intel RealSense D435 with ROS

How the Intel RealSense R200 camera works

The Intel RealSense R200 is a USB powered long range stereoscopic camera that can be used for robotics and HCI computer vision applications. About the camera The camera consists of two infrared and one full HD colour imaging sensors, as well as an infrared laser projection system. As a result, the camera provides three video…Read more How the Intel RealSense R200 camera works

Getting started with ROS nodelets

ROS nodes communicate using TCP/IP protocol which might be too slow for applications that require sending large amounts of data (like 3D point clouds or video streams). For processes running on the same computer, a pointer to the data can be sent rather than sending the data itself over TCP/IO. The Intel RealSense Robotics Development…Read more Getting started with ROS nodelets
