We found and based on your interests. I got the second camera and two degree wide angle lenses 1. After calibration the disparity was terrible. I figured it was because I used the clips on the back of the cameras to hold them in place. Indeed a small movement of the lens is enough to render the calibration obsolete. I think there is still room for improvements, but this proves the general feasibility of the idea. I tried to find some information about the electronics on the board of the camera, but like a lot of cheap Chinese electronics it seems the used chip is not very documented, or at least not in English.

There seems to be only one chip doing all the work, there are traces going from the camera module to it, and the USB lines are also connected directly to the chip. When calling lsusb in the command line it reports a 1e4e Cubeternet device for the camera. The manufacturer is listed as Etron Technology, Inc. The code on the component itself didn't help much either:. From the front the camera looks like it's missing a lot components.

The diodes D are connected to Q2 which looks like a typical SMD transistor footprint, so technically it's possible to add some LEDs to the camera board, which is nice I guess Also there is an 8-pin unpopulated footprint U5 , seemingly not a necessary part, omitted to lower production costs.

The traces go to the main chip, perhaps some memory? I don't want to spend too much time reverse engineering the hardware for now, as it seems to be working well enough to make a stereo camera with a pair of those.

Consistently recognising connected physical hardware is important, in this case as left and right cameras. First one needs to get the distinguishing information from the devices, for that there is a useful command:. This will print a lot of information about the devices. You should look at the block that starts with something similar to:. In there note down the idVendor and idProduct attributes for both cameras, these will distinguish the two devices. I received the camera and tested it. The image size is x pixels 0.

The image quality is not the best though and the lens absolutely not suited for the application. I opened the camera it to see if the lens was replaceable, the lens mount is a standard M12 screw-type, so I ordered a second camera and a pair of degree, 1. View all 4 project logs.

In your opinion, if correctly calibrated, this could work much better than yours? Is it possible to solve the shutters synchronization problem with an algorithm that gives me a frame tolerance? Are you sure? You should get some disparity in any case, the cameras seem to have excellent specs, the limiting factor will probably be the RPi. Nice work so far on this.

What software are you using, opencv? Keep us updated on the progress, if you want to collaborate at all let me know, I'm working on the same problem in the context of autonomous drone. The project is on halt for some time. The project on which I want to use this stereo camera isn't finished yet, so I just made a proof of concept. Now I'm dedicating my time to finishing other projects before I can continue this one.

There are may reason why stereo camera are expensive :. Those cheap USB camera are rolling shutter, cannot be synchronized or only with a hack and data is compressed to be streamed over USB2. If you want to sense depth on a DIY cheap robot you are left with :.

The Hackaday Prize. View Gallery. Description This project aims to build a low cost stereo camera using commercial off-the-shelf COTS parts and provide instructions on how to calibrate the stereo camera and extract a disparity map. Lots of robots could really use this kind of sensor for navigation, object recognition, obstacle avoidance Using two cheap cameras it is easy to build a stereo camera, however it's not straight forward to understand the complexities of image rectification, stereo calibration and output manipulation.

This project will be a feasibility study and a tutorial on how to build such a device. Lessons learned: The disparity only starts working at about 1. The lenses are not degrees, I barely get 35 degrees, perhaps it's due to the tiny sensor size. I ordered the second camera from the same seller on eBay, however the manufacturer was reported as Generic instead of Etron Technology, Inc.

Images are slightly unsynchronized, still the disparity looks like the one above even on moving objects at 30fps. On the back there is some code, possibly some production code: AXTOPDBY Also there is an 8-pin unpopulated footprint U5 , seemingly not a necessary part, omitted to lower production costs. The second camera arrived, but now how to distinguish between the two in Linux? To fix that Linux uses something called udev rules , there has even been a Hackaday article about how to set up a rule for a device.

Notice how the lens depicted on the eBay image is not the same as the one it was shipped with Pablo need it!

The Pride of Building A Webcam From Scratch | Make:

His goal is to use his knowledge to empower students to be able to make their dreams reality, by realizing that they can build anything they put their minds to. What we saw was a big smile and a look of victory. While students from other classes, who happened to be in the same lab space, seemed confused as to what could possibly be that exciting in a class lab, the students from my class knew exactly what had happened.

This student had streamed the first successful image from his handmade webcam to a web browser. To fully understand this experience, we have to take a step back.

Then, during my postdoc, my work led me to become heavily involved in the low-level development of an embedded device. When I subsequently became a professor at Northwestern University, I knew that I had to fill the educational gap I had noticed as an undergraduate.

The class that I designed centers on building a webcam from scratch. The students start by researching components. After that, they learn about embedded programming using C. Students start with a simple program that creates an edge-triggered interrupt that is activated with a pushbutton, and then they start writing the main code that will make the webcam work which they keep writing throughout the term.

This allows them to create a breakout version of the webcam, using these breakouts and through-hole components along with breadboards and wires. Then, they learn PCB design in Eagle, and students design their final webcam based on their breakout version. While the boards are getting manufactured, they design a website for the webcam stream, which is hosted on the WiFi module. After this, they learn CAD for 3D printing, and students make a custom 3D-printed enclosure for their camera.

At this point, the manufactured PCBs have arrived and the class solders their boards and connects everything for final testing. This entire process occurs during a ten week span. At the low level, the camera module captures an image and converts it to JPEG. The MCU has a parallel interface for camera data, so it captures and buffers this image.

Once they know the length of the image, they are able to transfer it to the WiFi module. Hopefully, the excited outcry described in the beginning can now be better understood. Students spend an immense amount of time in that lab, trying and failing, trying and failing, until finally a success comes along, and it is a major victory.

Students learn quickly that hardware systems are very difficult to design and debug, as a malfunctioning component could be due either to a hardware issue e. This is why, after spending hours and hours trying to capture an image from the camera and send it over WiFi to the web browser, something actually appears on the screen, students often scream or jump out of their seats.

They say they now know how to approach any design challenge, and are not afraid of complicated systems, knowing they could design them themselves if necessary. Latest Ilya Mikhelson.
