Re: default dot tracking parameters

Thanks for your advice, I finally got round to implementing it and it works great. Thanks!

Re: Single dot tracking interference

<t>I have tried tweaking the object_mass type parameters more carefully, and am able to prevent the infrared LEDs in the vicinity of the reflective ball from becoming the tracked object for more of the time. It is not totally consistent though, especially when I increase the distance of the reflecti...

Re: default dot tracking parameters

To clarify, I mean the C++ VC8 sample code.

default dot tracking parameters

<t>I am using the VC8 sample code for making my own application for use with a Slim v100.<br/> <br/> I want to be able to start the application with dot tracking parameters that are different to the default values. For example, for the OBJECT_MASS type dot tracking parameters I would like to be able...

Single dot tracking interference

<t>I am trying to optimise the single dot tracking of a reflective ball (roughly the size of a table tennis ball). The problem is I also have infrared LEDs in the vicinity (which can not be removed or obscured). Altering the dot tracking parameters like object_mass does help to favor the reflective ...

Re: IR reflectance with Slim v100

I set up an array closer to the lens and that fixed the illumination problem I originally described. Thanks for the good advice!

Re: IR reflectance with Slim v100

<t>Thanks for your reply. I will check out if this solves the problem. Its important for my application to have a large FOV - if I made a ring of emitters to go around the M12 1.9mm lens such that whole of its FOV was illuminated, could I get good tracking throughout the FOV with a retroreflective m...

IR reflectance with Slim v100

<t>My Slim v100 is not picking up IR reflected off markers properly. I am using a track IR 3 for comparison. When I put a marker in front of the track IR it picks up the reflected IR (emitted from track IR's LEDs) brilliantly, and does not pick up IR reflected off other sources (eg my hand). However...

Re: default values in c++ code

Thanks Birch, I followed your instructions and I can set the exposure value in the code.

Incidentally, does the API calculate the area of the IR source as a circle or a square?
