i have an intel realsense ZR300 camera , i want to use it to get depths of the objects (distance between the camera and each object ) using the camera in blind assistance system project , i need details for that ?

It may be useful to you to provide a history of similar RealSense projects.

A couple of years ago, a RealSense community member called McCool whose expertise was in robotics created a 'turtlebot' with navigation that could use a ZR300 and the ROS vision software.

Before that in 2015, some Intel employees created a system for the ZR300's predecessor the R200 called Spatial Awareness Wearable (SAW), which sensed obstacles and relayed signals to vibration pads on the body of the visually impaired person. That project relied on an old version of the RealSense SDK that didn't support the ZR300 though, so it would be difficult to convert that project for your own needs.

More recently at the start of 2019, an echo awareness application was developed for the current 400 Series camera generation.

Regarding your own project: if you are using the ZR300, the RealSense SDK For Linux (an SDK made specially for the ZR300) may fit your needs. It has a wide range of useful tools, including an "Object Library" that can recognize objects and output 3D coordinates.
