Plausibility of reading camera input and writing on it.

[pwillxorz]

I'm currently in a class where I'm studying augmented reality, and we're discussing possible devices to run our final projects on (we're supposed to have an AR experience we've made ourselves at the end of the class).


A lot of the class is going with iphones...... but I don't have the extra money to throw away for an iphone, let alone a dev license. I do however have a psp and access to the "official" webcam type deally. I was wondering if anyone's written drivers for capturing video and displaying it on the screen from the cam in homebrew. I've done a relatively extensive search on the subject, and though this is my first post, I've been on these forums for a few years, off and on... I've never actually programmed something for my psp, and would slowly ramp up to this project, but I'd like to know if some of the code I'd need is already available.

tl;dr version: I need to know of ANY and ALL webcam type drivers available to the homebrew community.

I'm not requesting people to write anything for me, for the record!

I have not used the cam in anything so I'm not really sure what source code is available,

Here are a few things that may help you get started,

Take a look at http://psp.jim.sh/pspsdk-doc/pspusbcam_8h.html

and http://silverspring.lan.st/5.00/kd/usbcam.xml

and http://forums.ps2dev.org/viewtopic.php?t=7074

Once you know the function names maybe google could help,

thank you so much!

You need absolutely Nanodesktop.
We've the tecnology that you're looking for.

Unfortunately, our servers are down until Monday, but you can
obtain infos at www.psp-ita.com

http://dl.qj.net has Nanodesktop.

Whats so great about Nano Desktop?

It is the most powerful tecnology for PSP development ever
realized in Italy. It has simple primitive for accessing to GoCam,
to the microphone, for network connection, an own graphical
system, a system for I/O accessing, disk cache manager,
file manager, VOIP, mathematical acceleration.

Other all, it integrates the support for OpenCV and a module for
algorithms of artificial vision. It you want to create applications
as augmented reality, Nanodesktop is the natural way.

This is a video of the new Blind Assistant CFW0005, the most
important application realized using nd.

But whats the differents from the pspsdk and Nano Desktop? Thats whats confusing me.

Nanodesktop works at high level.

Code: Select all

#include <nanodesktop.h>
int ndMain&#40;&#41;
&#123;
 int UsbHandleCamera;
 int Counter;
 ndInitSystem &#40;&#41;;
 UsbHandleCamera = ndHAL_CAM_ActivateCamera&#40;ND_USE_PSP_GOCAM&#41;;
 
 if &#40;UsbHandleCamera>=0&#41;
 &#123;
 for &#40;Counter=0; Counter<1000; Counter++&#41;
  &#123;
   ndHAL_CAM_GrabNewImage &#40;UsbHandleCamera, ND_CAM_TO_BASESCREEN, 0, 0, RENDER&#41;;
  &#125;
 &#125;
 else
 &#123;
  printf &#40;"GoCam is not connected \n"&#41;;
  ndDelay &#40;2&#41;;
 &#125;
&#125;

This program captures the images from the Sony GoCam and shows it
in the screen. Using PSPSDK you need hundreds of rows to
obtain the same result.

I might check it out.
