60 degrees apart. It cannot be a hundred meters anywhere else

So I see you know you need to overlap of I see what you're saying. Well, yeah, you have to have two perspectives

I'm going to read the

analysis

The problem is that when human but being move

Let's say we do a simple walking gate

There will be times when this foot would be in front of this foot and this

I wouldn't see the mark. Okay, so we need at least two markers by two cameras on each marker for a 3d

display, okay

What we do is we we spread these a little bit more and we'll add a third camera that way if this

Foot covers that point you'll still see it with these

Now that's a simple straight walking going in one direction. Well, that's not too much more remote

Okay, when we have a trubilary event

sent jazz golf

Where things are going all over the place there would even with three cameras there'd be points that would be this and that

So that's why we have five cameras

So that's that's not a basic format of what we do

So we grab the video and we're gonna describe it first and then we'll go through and we'll start doing some stuff

Okay, all right. This is a lot of hands-on stuff

So we grab the video in fact, I'll show you what I just did

In fact first thing I'll do is I'll show you the five cameras

We bring up cat TV and this little camera here

We can also do it a different way, but

This is a very simplistic you open it up. You set the file name

I'll call this bread one

It tells me that I'm putting a temporary path on the defile

But we can make that in here

So in this case I'm going to

Now this data path that's going to a separate memory card, or is that

This goes into the heart

That we think of C as hard drive we put the hard drive we split into a C in the D. Okay

Because we want you to store your stuff on D. You wouldn't want you

So

Well, we'll use a temper right now, but we'll create a new file later when we start doing our actual work

So temp is fine. I just say open this temp

It tells me that the data

The temp path is when you collect data it goes into a temporary file and then you have the opportunity to trim it down

You don't want to trim it then you want to save the whole thing you just say okay

Go and it puts it back in the temp in the temp file or whatever your name is

The way you're gonna actually do this okay, so in this case we have a file called bread one

Next thing is how long do we grab for where?

We're editing in the in the temp path or do we wait until it doesn't do that?

Grabs everything grabs everything and then it gives you an opportunity before you actually save it to the data

You can do that, but you probably want to do that

But what it does is gives you an opportunity to trim the file a little bit if you want

The way I'm going to teach you to do it probably

Let's say you're in the field you want to do a golfer out in the golf course

There's gonna be a lot of wasted films you want to do you want to go and trim it down to something magical

Okay, but for most of the stuff you do

Next thing is how long do you want to capture?

Well, you want to capture long enough so that you get the whole event

In the case of a walking gate you're going to do about three cycles

Three strides so probably five six minutes is adequate a

second

For many of the activities where we'll do TV analysis of the body part I do 30 seconds

I can be a really quick vision of variation

So this tells me that I have six cameras on

If I only wanted one camera and I know which camera it is I could eliminate them like that

In this case, I want to show you that the six are actually up and running and

You'll never have to change this

This is this is in case you want nine of yours and you have to have two computers say this one starts with number one

First in number six this computer goes seven and one away

So that's good we'll say okay

It's zoomed

So we have six cameras are live and everything is good

You can unzoom it anything

Yeah, no you didn't it was on a play mode and still on a play mode mode

But now it's okay to stay

Now I'm ready to go I have to do two things

I have to put a calibration cube in the field and save that then I have to do the actual bit the calibration

You really have to say for a half a second. I need one really good frame

So in this case, I'm saving five seconds and I say okay ready and go now. It's capturing

Do that so we know we have something and make a noise the noise is for synchronization

What's too late? I'm going to cancel this and we'll do it again

The sound is a synchronization. Okay

If you're hitting a golf ball, that would be the same point for gee what I do is I tell the person

I'm going to clap as soon as you start don't be startled

Yeah, they take a step out and start moving the second foot and I go like that right now. I do it like this

Because I'm standing over here now, but I can see my hands go together as well as here

Okay, so in case some reason the sound failed again. I would still have this to synchronize on

Okay, so you should be and I can easily see when the when the cameras are are the same position

In order to digitize more than one view would have to make sure that the camera views are synchronized, right?

So in this case I'll start

Those five seconds

And the really important thing is to make sure you don't drop anything for some reason a number of five drops

Because if you happen to have a cycle that drops and God knows what happens in Microsoft anywhere

Some of the things going on you want to make sure that these are all yours

So you have this triggered to a stick that no, I said I started the camera collecting with this right the clock was a synchronization

I'll show you in a second where that comes in

Now if I say manually sync

It doesn't do anything if I say auto sync and I say sync over here

Now listen

It searches each film it points to the class the loudest marks. Okay, I'll try to adjust

Okay, so we heard six noises we know that everything's good now. It's gonna give us the whole scale

Okay sync it shows me where it found the same point to the views and I said sync and now we have this little graph and

There's you can't see them but there's actually six waters on there. Okay, and by going from camera to camera

It shows me where the same point is

And what you've seen a little differences here are half bridge

Let me back on you statement him if we didn't have the same

You
