Sausage Analysis Software (SAS)Exciting news: at Basler we are exploring new opportunities in the Point-of-Sale markets (POS). In our large network of friendly partner companies we get a lot of chances to work on special camera projects. We don’t produce any “end-systems” but often produce special cameras for special markets. There is one very exciting project here just entering its production phase. It is a joint venture with a leading german “lebensmittel” producer. The camera has been nicknamed here “das Würstli” and is used for food inspection. I like the name because it’s got an umlaut in it – and umlauts are cool (ask Mövenpick).

One recognised problem of the food industry is the quality of the end product especially in the fast food world. It doesn’t matter how good and clean you produce your raw product, if the end delivery station (the sausage and chips health bar around the corner) doesn’t correctly cook it – then it’s all for nothing. So why not check the product at production and then at final delivery? Hence the sausage inspection system (SIS). The idea is every manufactured sausage gets inspected and recorded. Then they get cooked and sold and at the point of sale (POS) the SIS does the same and sends its information to the database.This way the producer can check that the consumer gets his or her product in the best possible way.


A protoype of the forthcoming POS sausage checking installation. This is only a test version we have built up to see if the concept works. The construction department has to see if they can reduce the size a bit for the final product. Can also be used for endless sausage inspection.

The clever bit is the sausage analysis software (SAS) which can uniquely identify a sausage due to is wurst-druck (sausage print). Every sausage has it’s own wurstabdruck (like a finger print) and the SAS can recognise this. The software is still in prototype stage and the initial system will instead work with an embedded RFID tag (which the consumer will have to remove before enjoying the product). The advantage of the RFID tag is also that a consumer with a NFC enable phone can download the app and see which farm the pig came from (interviews with explicit pigs will also be possible so you can get to know your dinner before eating it).


Prototype of the SAS. The computer correctly identifies the sausage ID and analyses it. The health plugin in test is shown. This will not be available inside europe due to the data protection act (otherwise health insurance agencies could determine the health of potential customers and this would negatively affect them). Newer version of the software can also deal with chips on the plate.

The initial version is only for the northern german sausage, but we are working on export variety for salami and weißwurst. Weißwurst is presenting us special problem due to a misfunctioning white balance correction (it only works with black plates at the moment). The camera is already creating a large amount of interest in the swiss research community. Ketchup is also a problem, but we hope with a complex red pixel Hough-Kunze removal filter to get rid of it.
Soon all these sausages will be supported by the onboard SAS.

Soon all these sausages will be supported by the onboard SAS. The inspection will work over a spline fitting function (codename FrameSausages). A separate camera will be required for the salad inspection.

This is a very exciting phase of Basler moving into the point-of-sale market. If it works I will soon be able to show my children and friends “our” cameras at every “Frittenbude” (northern german equivalent of a health food bar).


This article was published on the birthday of Otto von Bismarck (April 1st). Famous for two things: the unification of Germany in 1849 and his sausage quote:

Laws are like sausages, it is better not to see them being made.

And if you hadn’t yet guessed… April Fool!

    I am quite interested in such a machine. We have been pursuing such development for some time, but it has been very difficult. I see an opportunity to resell such a device in volumes of 200,000-500,000 / yr,

    Can it be extended to bacon and other processed meats? Scrapple and Haggis are also adjacent markets for us, and growth is expected.

    Please provide best pricing, availability, and shipping options to Pyongyang.

    Is such a device compatible with DOS and Vic20?

    • Always good to find new markets for new products. We will be in contact with you shortly (we have to finalise the port to the ZX Spectrum and Amiga ST first).
