Hi, just wanted to share my project. I'm using a raspberry pi + RPi camera board + far IR sensor + arduino to detect when people are wearing a mask. The basic idea is pretty simple: use OpenCV to find a face in the photo, and then get the temperature at that location using the IR device. Not bulletp...

One of the reasons NIR is used for iris recognition is to reduce reflection, so you might want to experiment with different filters. However, there are algorithms for recognition in the visible spectrum as well, so the Pi NoIR seems well suited for such a project. There's lots of open-source matchin...

Thanks for making this code available. I was just looking at the source, and correct me if I'm wrong, but it seems that it is processing/face-finding the frames at 7-9 fps, but they aren't necessarily new frames. That is still limited by the speed of raspistill timelapse mode, which is about 1 fps? ...

In Icelandic: Hæ Kári. Lítur mjög spennandi út. Ég hlakka til að heyra meira um þetta verkefni!

For anyone else who has this problem, I think I have found some relevant information:

It looks like there is something about the way the RPi issues an I2C read command that is not compatible with this sensor.

Is there any reason why the RPi would be unable to read RAM using I2C? Details: I am trying to get my RPi interfacing with the MLX90620 thermal sensor The MLX90620 has both EEPROM and RAM. I am able to read from EEPROM, write to RAM, but not read from RAM (code below) I found a blog post that says: ...

I was having the same problem, but with a different pin (BCM 17). In the end, it turns out there was an driver loaded at boot time that was preventing me from using all the GPIO pins (it was for LedBorg). Now that I look at their site they are clear about this. However, I hadn't used the component f...

Cool - good find! Any idea how easy it would be to interface with an RPi? Just today I came across this: http://www.melexis.com/Infrared-Thermometer-Sensors/Infrared-Thermometer-Sensors/MLX90620-776.aspx Super-low resolution at only 16x4 pixels, but it is a true thermal imager (thermopile technology...

I'm at the very early stages of a project idea. What I would like to do is experiment with stereoposis. The basic idea would be to have two CSI cameras and combine them to get an estimate of depth. I'm assuming there won't be enough computational power on a single RPi to run 2 cameras and do all the...
