In Search of a Better Serial Camera Module

So I've been looking everywhere for a cheap serial camera to use in my projects, preferably with some basic image processing, like object or motion detection etc.. The cheapest one I could find that barely meets my needs is sold on adafruit for $35, it has a 640x480 pixels sensor and can do some motion detection but nothing more. Then there is the more expensive modules which cost around $40 that do nothing at all and finally there's the CMUcam, which has some really nice features, but way too big and expensive (costs $100) for my needs...

So I decided to make my own serial camera, keeping in mind the basic set of features that I want:

Low cost
Small form
Basic image processing
Open source (duh!)

First, I had to choose an image sensor to use, I was inclined to use the TCM8230MD, which I'm familiar with, however, the sensor alone costs $10 and I can't seem to find it any where else other than sparkfun. So, I've decided to try the Omnivision sensors, the cheapest one I could find is the OV9650 (1280x1024 pixels) sold on ebay for $2... The nice thing about this sensors is that it connects to the board with an FPC cable (that flexible yellow cable), which means it's possible to replace it later with another one (assuming it has the same pinout) and it also has a higher resolution than the TCM8230MD. The downside with this particular sensor is that it doesn't have JPEG compression, but I could live with RGB/RAW output, after all I plan to use it mainly for image processing, or I could try to implement the JPEG compression on the micro.

Moving on to the microcontroller, a powerful micro is needed to interface with this sensor, preferably with a DCMI hardware interface, I implemented a DCMI before in software with an LPC1768/TCM8230MD and it could barely keep up, so I decided to go with something faster.

Fortunately, I had a couple of STM32F4 micros laying around, which seemed perfect for the job since it runs at 168MHz, has a hardware DCMI (should make it a lot easier to interface the camera) and as an added bonus, it has a floating point unit and vector processing (SIMD), making it perfect for image processing... Unfortunately, the DCMI only comes with the LQFP-100 package, so I couldn't use a smaller one.

I started working on the PCB, first, I made a footprint for the sensor and its connector, which seems to fit nicely:

And then I moved to the layout,

OpenMV Update: 25FPS Face Detection, USB Support and More

So I've been working on OpenMV for the past week and this is what I have so far:

USB Support:

The camera now supports USB OTG full speed, I've also written a small userspace tool with libusb/SDL to interface with the camera and view the frame buffer, this makes it really easy to debug the image processing code, and it also lets you change the sensor's registers while watching the results in realtime.

I've mentioned building the STM32F4xx libraries in a previous post, you can checkout the repo linked there if you want to build the libraries.

Face Detection:

Many were very interested in this feature, well I've managed to get the viola-jones face detector working on the camera, and it's working fine.. For those of you familiar with the detector, the haar cascade is exported as a C header which is linked to the binary and loaded into the CCM (Core Coupled Memory) a 64KB memory block connected directly to the core. Only one integral image is pre-computed and allocated on the heap, the other one, the squared integral image, which is used for computing the standard deviation, can't fit into memory for the QQVGA resoultion, and so, instead, the standard deviation is computed on the fly for every detection scale using some SIMD instructions to speed it up a bit.

Pyzo - Python to the people

Posted on 13:40 by Unknown

Here's a new (to me) IDE for the Python Programming Language. It's called Pyzo. Check it out..

Don

Why Pyzo — Pyzo - Python to the people

Python and free software

Open source software is made by people who love writing code. Therefore the quality can be comparable to that of commercial software (and sometimes even better). The Python programming language is the basis for a large community thriving on open source software, and is used for a broad range of tasks.
Python is designed to be easy to read, and might well be the easiest programming language to learn. Nevertheless, it is really complete and powerful, and by using extension code, the crucial parts of an algorithm can be made as fast as C. Due to its open nature, Python is easy to extend. In this manner, people have been able to introduce technologies to Python such as USB interfacing, OpenGL, various GUI toolkits, and GPU computing.

Skipping on down...

With Pyzo we will build a coherent scientific Python environment that is easy to use for normal people. The Pyzo distro will get you a basic setup suitable for scientific programming. But the installation is transparent, so additional packages can be installed in the conventional way.
We have been working for several years on our IDE, and we’re getting very positive feedback. IEP is the portal through which one uses Pyzo.
We engage on improving standards and documentation of our own packages as well as that of other projects. Further we will develop more tools to use the documentation from within the IDE in an effective way.
We offer informal support through our mailing list. We think that we can be a good “middle person” between the normal user and the open source developers, by filing a bug report and helping the user to a temporal solution, or by simply solving the bug and sending a patch to the developer. There are plans for paid support as well.

Abstract

Technical progress in the open-source self replicating rapid prototyper (RepRap) community has enabled a distributed form of additive manufacturing to expand rapidly using polymer-based materials. However, the lack of an open-source metal alternative and the high capital costs and slow throughput of proprietary commercialized metal 3-D printers has severely restricted their deployment. The applications of commercialized metal 3-D printers are limited to only rapid prototyping and expensive finished products. This severely restricts the access of the technology for small and medium enterprises, the developing world and for use in laboratories. This paper reports on the development of a <$2000 open-source metal 3-D printer. The metal 3-D printer is controlled with an open-source micro-controller and is a combination of a low-cost commercial gas-metal arc welder and a derivative of the Rostock, a deltabot RepRap. The bill of materials, electrical and mechanical design schematics, and basic construction and operating procedures are provided. A preliminary technical analysis of the properties of the 3-D printer and the resultant steel products are performed. The results of printing customized functional metal parts are discussed and conclusions are drawn about the potential for the technology and the future work necessary for the mass distribution of this technology.

Snow Sleet and Ice in Azle (DFW) TX 12-07-13

Posted on 14:12 by Unknown

We had Ice and Sleet yesterday (12-06-13). And it is still here, today (Saturday). It is supposed to stay till Monday or Tuesday. It was 80F the day before the Cold Weather came in!:O I haven't been outside, any further than the Porch. To take some Pics. I made a Slide Show Video of my Pics yesterday.

Snow Sleet Ice Azle TX short by Don Bishop 12-06-13

Or You can watch it on YouTube here, https://www.youtube.com/watch?v=tuh_Uasc-w8

The Roads are very Slick, every where. So, I've seen on TV. Since, we don't have many Sand Trucks or Snow Plows in our Area. Most of the Roads, don't get Cleared of the Ice. Many Trees and Big Limbs have fallen on Homes and Cars, from the weight of the Ice. And some Car Port Covers have fallen on Cars too. And on some Apartment Complexes, in the area. And some Boat Covers at one of the Lakes. Fell on the Boats too. It's quite a mess, when we get this kind of Weather here. Since, we don't get it very often. We are just not very prepared for it, here. If your from a Cold Regen, that gets allot of this kind of Weather. You would probably laugh or be afraid of the Drivers here. When we have Ice on the Roads. They do some crazy things! Oh, and "Saturday morning, more than 130,000 customers remain without power in North Texas." And "The airport’s focus on Saturday was on airfield surfaces and public roadways, in addition to accommodating about 3,300 travelers who were forced to stay overnight in the terminals." Here's is a local News Page, with some videos, http://dfw.cbslocal.com/video/. It's 24F now and it's not supposed to get above Freezing Today. It's "Beginning to look allot like Christmas". But, I'm so glad that we only get this kid of Weather, a few days, each year. Stay Warm!:)
