I want to design real time depth measurement system. so, which type of camera is compatible for Raspberry Pi 3 to get depth.
You're unlikely, I think, to be able to do this with any Pi model other than the Compute Module.
The Compute Module includes two ZIF connectors which can be used to attach two Raspberry Pi camera modules. The bandwidth available to these cameras is substantial, and the compute module is just about capable of rendering depth maps from the data produced.
The Pi 3 has only 1 CSI interface, so you can only attach 1 Pi camera board, which is of no use for stereoscopic vision. You could try connecting 2 USB cameras, but given the limited bandwidth (circa 480Mb/s) and unpredictable timing of USB cameras I think you're going to have a hard time getting enough synchronised data from them to create a practical depth map.
