ZR300 to use pre-made video or image instead live capture

SS26 — Tue, 09 Jan 2018 14:38:13 GMT

Hi,

I want to use pre-made files instead of live capture.

1. what is API used to load pre-made files and catch the frame by frame?

2. Is it possible to use to detect/track person any general video/image files which captured using any other camera's ?

3. Is it possible to track Leg using Body Tracking library (Skeleton tracking)

4. In Body Tracking, it it possible to calculate angles, Length of hands / Legs ?

Hello Sakthivel-S,

Thank you for having contacted Intel Technical Support.

To answer your questions:

It is possible to record and playback video samples using the ZR300 camera and RealSense SDK APIs. The playback takes the place of the actual device stream. See this sample for details on how to use the API:

https://github.com/IntelRealSense/realsense_sdk_zr300/blob/master/samples/src/playback_async_sample/main.cpp

This developer guide gives more information as well: https://software.intel.com/sites/products/realsense/sdk/developer_guide.html# Playback

Details on the Person Tracking feature can be found here: https://software.intel.com/sites/products/realsense/person/developer_guide.html

For Body Tracking the following is possible. You can calculate angles and lengths using the provided points. Lower body is not supported.

Body Tracking

The goal of this feature is to track the location of certain body parts. Currently, four parts are tracked: Head, Shoulders, Chest, and Hands.

Output: For each of the following points, the image and world coordinates are provided:

Head COM

Shoulder points approximation

Chest COM

Hands extremity points

From <</span> https://software.intel.com/sites/products/realsense/person/developer_guide.html# 1.2_Additional_Concepts_and_Definitions>

It is not possible to do this with videos from other cameras.

I hope you find this information helpful.

Do not hesitate to contact us again if you need further assistance.

Hi Josh,

1. I need a video, which is recorded using intel zr300 camera. Please let me know any link is available to get the video for testing purpose.

2. And also share any other intel realsense camera video captures .

3. While executing playback sample I got an error "failed to create playback device".

Is this expecting Intel realsense camera device should be connected ?

Hello Sakthivel-S,

That error occurs when you try to playback a file that is not valid. The ZR300 does not have to be plugged in to playback a file. Try this:

Record a sample file using /realsense_sdk/build/samples/src/record_async_sample

Then playback the file using /realsense_sdk/build/samples/src/playback_async_sample

Hi Jesus,

Thanks for tour valuable support.

I need a example video now. Could you please share a already recorded video link or video to use it with examples you have mentioned.

Since, we are yet to receive the device, before that want to check some examples of Realsense.
