intel realsense sr300 object tracking

LMart13 — Fri, 04 Aug 2017 09:32:16 GMT

how can i track the same target identifier of an object every time?

it seems not returns the same trackvalue of an certain object

Are you using 2D or 3d object tracking, please? And are you using the RealSense SDK in Windows or the RealSense SDK For Linux?

In the RealSense SDK for Windows, the object tracking documentation says that you will get more reliable results if you use 3D tracking for objects whose position is moving. For stationary objects such as a table or an object sitting still on the table, 2D tracking may suffice.

I tried both,neither 2D nor 3d object tracking stable. And i use the RealSense SDK in Windows.

i want to calculate the rotate angle of my object,so i want the same point.but when i rotate my object ,the trackvalue become werid

how can i ensure the same trackvalue of the object?MartyG,

please help me.

There was an object tracking script for the F200 (the SR300's predecessor camera) that calls QueryAllTrackingValues. By doing so, it provides information on both the rotation and position of the tracked object.

QueryAllTrackingValues returns trackvalues[5]. how can i fix one identifier,so i can calculate the rotation angles relative to previous identifier.then i can calculate the correct rotation angles of the object.

if everytime i use QueryAllTrackingValues returns different identifiers,i don't know the exact rotation angles of the object relative to the previous pose when the object rotated.

is there any functions can return the assigned identifier,no matter how i move or rotate the object.so that i can keep the same pose all the time.it's important when i want to pick the object when the object pose changed,

the accurate angles should be returned.:(MartyG

let me describe my application scenarios for short:

i use my gripper to pick some object.and first of first.i should tell my gripper the initial pose and the final pose of the object(the angle and the position).

so the tracked thing should be the same identifier on the object,if not i can't calculate the exact position and the angles.these can be useful when my gripper want to grab the object.

if the tracked object rotated and moved,then my gripper should rotate the same angles and move the same distance relative to the initial pose.rather than the random rotation and position returned from

QueryAllTrackingValues or QueryTrackingValues,

do i need to mark the markdID on my trakced object.but the align map worked not so well.it affected by the light or other unknown reasons,i dont know.

QueryTrackingValues is supposed to return the values of a particular identifier (cosID).

I wonder if another way to achieve your project goal would be in the RealSense implementation in the Unity game engine. The RealSense SDK provides a script called TrackingAction that can be set to object tracking, to change the position and rotation of a virtual object based on the tracking of a real-world object.

please give me a link of this TrackingAction software

the questions is how to align a cosID,returned IDs are random.

can i use this script to set my interest identifier,and export as code snippet ?

Unity can be downloaded from here. Once you have done that, I can explain the further steps for setting up RealSense in it.

Unity sees like a game related develop tool.Hope it will useful

Yes, Unity is a game creation engine. It is very powerful, and I use it for my own game project.

You can learn more about using RealSense with it by reading my large range of how-to guides for it. Good luck when you get to try it on the 6th.

Since my project is not a game project,Unity is not helpful.

Is there any other ways to fix cosID on the object ? like align map,not worked so well.

Re: intel realsense sr300 object tracking

sr300 can't be used to track certain object .if the result is random,it cant be used to do anything.

Although Unity is primarily used as a game creation engine, it does not mean that you have to make games with it. You can use it to make serious projects too. You can think of it as a visual object programming environment.

It is true that some objects are harder to track than others. For this reason, RealSense has a 3D tracking mode called Edge Based Tracking that may be able to follow objects that other tracking modes cannot. What kinds of objects have you found cannot be detected by the tracking, please?

In RealSense's 3D model scanning feature, objects with surface curvatures that are difficult to detect can be made more easily detectable if you place other objects in the background, as it helps the camera to lock onto the object you are trying to scan. Maybe you could see if this principle works with object tracking too.

I dont know how to align the cosID of the object with Unity.Your samples are all about virtual object.
