Stereo camera technology

Stereo camera technology is based on the principle of observing an object from two points of view at the same time.

The stereo camera technology can handle a large variation of surfaces and materials and has other properties that make it extraordinarily suitable for the applications developed by CIND. The ability to measure objects in movement with a high degree of accuracy, as well as the ability to efficiently process large flows of products are among the biggest advantages of our  applications of this technology.

Since our stereo camera system does not use any lasers or other potentially harmful components, there are fewer limitations for installing it than for other solutions with similar functionality.

The system is comprised of relatively few hardware components compared to other measurement systems. It consists of two cameras, computers and a few other IT components, as well as lighting (if necessary) and the mechanic components necessary for installation.

Our system handles most measurements continuously during the real time flow of goods – something of a challenge before due to the complex calculations necessary to use images as a basis for measuring the flow of goods.

How it works

Our cameras are set up with a known distance between them and with a calibrated angle between their lines of sight. Because of that, it is possible to measure x-, y- and z- positions of every point in the image with a high degree of precision.

The precision of the measurements are decided by the camera resolution. If we assume that we use cameras with 10Mpx resolution, i.e. 10 000 000 pixels spread over the surface of the measurable object, we can see that there is a large potential for precise measurements.

Stereo camera technology is already being used in other fields, such as mapping. CIND and SAAB are now implementing the speed normally reserved for flight industry calculations to make it possible to measure product volumes in real time, continuous flow of goods.
