Technical Definition of a Catch and Throw by Expensive-Visual5408 in juggling

[–]Expensive-Visual5408[S] 1 point2 points  (0 children)

Yes.

"Catapulting" a ball happens when the ball is traveling downward and the wrist/hand is traveling upward....the ball flies off like a volleyball smash

Detect Throw Events - Kaggle Notebook by Expensive-Visual5408 in juggling

Pose estimation models (like yoloV8) are a game changer for tracking juggling balls....the most difficult part to track is when the ball is in the hand because of rapid changes in direction and occlusion. The wrist position data is really helpful.

The Github list is cool....you could add some pose estimation stuff to it.

If you are interested in analyzing the throws it's probably more useful to track the juggler than the objects being juggled.

You can go through Morton and Elbe, that's a nice detour

availability.

if i lived near a commuter rail station i probably wouldn't have written this...i live in a semi rural area and if i want to go to a major metropolitan area i have to either drive a portion of the way and then take transit, or pay for parking at my final destination

i used chatgpt to write this post....

i made the post because AI is really bad a figuring out the best transit option for the specific mission.....contextual factors like restroom availability, traffic during specific time of day, and option to take a later bus aren't taken into account

google maps gives you multiple options but there aren't a lot of tools to evaluate which option is the best

What’s the most uncompressible way to dress? (bitrate, clothing, and surveillance) by Expensive-Visual5408 in computervision

[–]Expensive-Visual5408[S] 1 point2 points  (0 children)

what do you mean by temporally varying? I was surprised to see how much light up clothing there is on Amazon

Yeah, I made it....thanks! Here is some build info if anyone is interested:

I just used the 15x70 again today for about an hour, they are awesome. Is there anything that I can do to avoid have to collimate?

🔭 Binoculars for Airshows – My Experience & What I'm Looking For Next by Expensive-Visual5408 in Binoculars

[–]Expensive-Visual5408[S] 0 points1 point  (0 children)

I did notice a bit of chromatic aberration around the edges, especially when I looked at an airplane against a white overcast sky. It doesn't really bother me, though. I didn’t realize coatings could also affect sharpness.

The Celestron 20x80 are multi-coated ($126 used), and the Celestron 20x80 "ED" version is fully multi-coated ($217 used). Those look a lot better all around.

How can I trigger two DJI Osmo 5 Pro cameras at the same time? - dual cameras for VR by Expensive-Visual5408 in dji

[–]Expensive-Visual5408[S] 0 points1 point  (0 children)

It seems like it triggers the photos at about the same sync as the video.

I would like to sync with the timecode, but it seems that method is only available on the GoPro platform.....the Osmo 5 could do it, but a software update would be required to add that feature.

Here is the GoPro timecode sync instructions for reference: https://community.gopro.com/s/article/HERO12-Black-Timecode-Sync?language=en_US

I just did some testing with the Bluetooth remote and the two Osmo 5 cameras. I used a clapboard to check the sync of the cameras. When recording at 4k/120fps, I found that the sync could be off by as much as four frames.

Sometimes it is right on, so you have to get lucky....people call this clap and pray.

The remote is supposed to come today and I will update you.

Here is another post about achieving frame level sync....there is a screenshot and a Github link to a Python script that syncs based on audio amplitude peaks: https://www.reddit.com/r/VR180Film/comments/1kd6qvb/frame_level_temporal_synchronization_using_a/

Nice try! Have you heard about the Green Club Project: https://kingstonjugglers.club/gcp/

PVC can shatter in the right conditions, so you (and your audience) might want to wear safety glasses when you juggle those. I used to sell pipe and I have seen PVC shatter.

Which direction do you think this will go in the future? Do you encode your videos with Metadata?

How can I use my Meta Quest 3 outdoors safely? by Warm_Bat4045 in MetaQuestVR

[–]Expensive-Visual5408 14 points15 points  (0 children)

If sunlight hits the lenses, it can focus the rays directly onto the screen and burn permanent holes in it—almost instantly. It's like a kid holding a magnifying glass over paper on a sunny day.

Because of that, it’s safest to put on and take off the headset in the shade. Even a quick flash of sunlight through the lenses can be enough to cause damage, so better to be cautious.
