detecting a rectangular beam

August 8, 2018 - 10:15pm #1

hi,

For my application i want to detect a rectangular beam and render a video as shown in this video

https://vimeo.com/215520764.

Can i implement something like this using vuforia and how?

how long(distance)  can  i place augmentations is extended tracking?

any help would be appreciated

Hello,

One additional thought about the jitter you're observing: For optical see-through devices (such as HoloLens), the printed target much match the dataset's target size exactly. Recall that the Target Manager works exclusively in the units of meters.

This differs from 2D planar targets on video see-through devices where the aspect ratio of the printed target must match what was uploaded to the Target Manager (and is in your dataset).

Just something to keep in mind during your HoloLens testing.

Thanks,

I cannot speak to HoloLens capabilities. Vuforia does provide the ability to recognize images.

If Vuforia's Extended Tracking is enabled, it will recognize the target and then hand-off tracking to HoloLens spacial tracker. The jitter may be related to Vuforia's Extended Tracking not being enabled as real-time tracking with the HoloLens forward-facing camera is a sub-optimal solution.

As previously mentioned, it is unlikely that a feature-poor (and geometry-poor) rectangular beam could be reliably detected by Vuforia.

Just to clear some doubts

1.Using hololens spatial mapping can i map an office area and anchor employee profiles near workspace ,also trigger this  employee  profiles by a good image target (logo )and using extended tracking.

2.when I am using multiple image targets for my application i am getting ar camera shaking (Jitter).So I am thinking to use extended tracking + spatial mapping with hololens.

Hello,

First blush is that it is unlikely that a feature-poor (and geometry-poor) rectangular beam could be reliably detected by Vuforia. If there was something else for the detection algorithm to grab onto (company logo on or near the beam), then HoloLens spacial tracking could take over once an initial pose was derived by the detector.

With HoloLens, the Extended Tracking is only limited by their spacial mapping tech.

Thanks,
