180×180 Apple tree fisheye test

This photo was made by using a pair of wide-angle (187° circular fisheye) SOHO cameras mounted on the stereomaton (in automated mode). Although any additional filters were applied, the exposure is not good and the color balance is worst (bigger artifacts manually corrected afterwards). I think there...

Re: Upgrading/New Drivers

there is a difference between make and sudo make . The difference is that executing through the sudo command, the make program get root privileges. You can remember it as sudo=" s uper u ser do ". It is always better to reserve execution with high privileges to the tasks that really need it, such a...

Re: Ethernet failure?

Thanks. As I work mostly with headless systems, I did not think at all about this way that might be obvious for others. It sounds strange that the hardware used to work and broke. Maybe a weak soldering on the connector that was damaged with manipulation (connectors and their connections are often w...

Re: Ethernet failure?

I don't get how you can have a terminal to type the command if the board has no network access. Anyway, even if I am very surprised and puzzled, glad you solved your problem.
As a simple user, I cannot answer the warranty part.

Re: camera calibration for stereo photo

Doing it automatically is not very simple, and you have to have a valid calibration of your system beforehand. If you want to do it yourself, you can get inspiration from the code of the stereomaton: https://github.com/haum/stereomaton/blob/master/code/stereomaton.py Lines 209 to 222 do the alignmen...

Re: Ethernet failure?

Woo. Strange story. How do you determine the IP it get? Could you draw a sketch of your network installation? If you had to change your hardware several times, there might be something you do not understand or something in your installation that interfer. With such problems, I would start to try to ...

Re: StereoPi schematics

The schematics are already published in PDF. Also, the kicad suite is a free software (both like in liberty and in price) so you can easily install it to inspect the design (which would not be possible with Altium). These are two possible ways to have access to the schematics before realizator answe...

Re: GPIO issue

I did not know this extension before, but it likely not use bare GPIO, but rather the peripherals such as I2C bus which are also available on the GPIO extension connector. There might be peripherals and drivers to enable, which is generally done through the device-tree or device-tree overlay mechani...

Re: 3,5 sreeen

The installer script possibly try to install the software without updating the list of available packages in the repository, thus maybe it tries to download something that was updated between the last update and now. Try to run "apt update" to update list list of packages before running your install...

Re: 3,5 sreeen

Realizator, it is possible to flash a ext4 partition with the bare minimum and then extend the FS to the whole partition with "resize2fs /dev/mmcblk0p2". In the application I have in mind, we do it to extend the size available to the user to several GB based on a system image of 120MB. I guess (not ...

Re: 3,5 sreeen

The error is just written in the log very explicitly: you do not have enough free space (to download the software your installer try to add).
What is the question?

Re: StereoPi Field Report

Ok, I've uploaded DWG, STL and OBJ models of the board I tried to open the DWG but the only software I know to open this format on my system has an experimental support and crashed. I used an online converter to get a DXF. The drawings are heavily detailed, but a part of the components are not in t...

You probably have read the article about the design of the case:

Re: StereoPi Field Report

It is nice to have a preview of another field report, but it would have been better to open a new post. Nice proposal by the way. I also was frustrated to not find this measure on the wiki when I designed my case, so it would indeed be interesting to add it. The position of the camera connectors rel...

Re: Batteries and typical power consumtion?

The amperage is what the boards (processor, cameras & co) will try to get from the power source. It can be almost 0 if the components do not consume and grow when you compute (get video frames, encode video, write to the SD, and do on). If your power source can feed it (its rating is superior), all ...

Re: StereoPi schematics

Wonderful. I found easily the components I searched both on the Kicad project and on the actual board. Unfortunately, the mod I wanted to do, to change USB otg/host automatically with cable plugged, will be trickier than I hopped as the related components are on the opposite sides. I planned to dril...

Re: button

Then you go for the hard way ;) I already gave an overview of the architecture we use. It is probably not the best solution because we had to make it work before a hard short deadline. As I said, I think that starting from the disparity map tutorial would be a good (probably better) way. In addition...
