Things have moved on a bit since the last post on this subject. The first thing that is noticeable is that it looks much more like a proper application. The tools to the right are lined up better, and when the window is resized, the window’s contents don”t completely fall apart!
I have a small fascination with Metric Time. The continuance of the French project to measure the world in sensible, easy to understand units. Like the Metre, the Litre and other metric units, Metric time divides the day up into easy to comprehend units. So, you get 10 hours in a day (instead of the normal 24), and each hour is divided into 100 minutes, and each minute divided into 100 seconds.
After my last post, I’ve been looking at a number of GUI tools that I can use to create a control system in Python. I finally settled on WXGlade, simply because it’s pretty much as close to what I am familiar with as I can get.
I say “as familiar with” because the way it works seems to be much the same way that web sites were once constructed – by using tables to handle the layout. This seems to be the way of things with this kind thing in the world of Python, and it seems to be that it works this way because that’s how people choose to work. So no dragging elements around like you would, say, in Xcode on a Mac when creating a UI for a phone or desktop machine. Continue reading Stereo Camera UI→
Since the last post, I’ve made more progress – which I guess is a good thing. The actual results of the so-called camera have not changed, but things have changed to speed it up.
Firstly, I have a new Raspberry Pi (a birthday present from my wife who feels I need more encouraging) – this is a model 3 B, so it has a quad-core processor, is faster and has more USB ports – allowing me to connect all the cameras AND a keyboard at once. It also has WiFi built-in, so it’s suddenly portable – I’m not restricted to where the Ethernet cable will let me go. Continue reading More on the Stereo Camera→
This is an experiment that I have been thinking about for a while (and I expect I am not the first person to have a stab at this). I wanted to see if I could make a stereo camera with a Raspberry Pi and a couple of web cameras. As I already had a Playstation 3 camera and I found another in second-hand shop for £1.50, I decided that this would be the best option to see if the thing would work. The PS3 cameras are a bit rubbish, and output to 640×480 pixels, so the images aren’t great (I’m scaling them up at the moment to the target size, eventually better cameras will result in scaling down which will give better results).
