Motion Capture System

Motion capturing systems are used to record industrial, human or animal motion. There are a number of ways this can be done. Our system is an optical based system where several cameras are used to compute the 3D position of a set of markers. Very advanced calibration and tracking algorithms ensures high precision 3D-measurements enabling e.g. analysing fine details in human motor control or high accuracy biomass estimation of fish. All movements can be visualized real-time. The 3D positions can be used in various kinds of systems (physioterapists, sports, game industry, surveillance, simulators++). 3D Motion Technoligies AS are currently working within two interesting areas: Welfare technology and Aquaculture.

Welfare Technology

Although the term Welfare technology has its roots in a Nordic context, many people are more accustomed to similar terms such as Active Assistive Technology or Ambient Assisted Living. They are all related in that the objective is to use technological solutions to aid people in daily tasks. 3D Motion Technologies AS are currently focusing on gait analysis. Gait is the way in which we move our whole body, most often, this is done by walking. We are using our software to generate data to carry out gait analysis. The data produced from our system can be used to ie:

• analyse and perfect athletes movements
• highlight biomechanical abnormalities. Having joints capable of providing sufficient movement and muscels capable of producing sufficient force is vital to generate an efficient gait cycle. If joints are stiff or muscels weak, the body must find ways of compensating for the problem, leading to biomechanical abnormalities.
• gait recognition: an emerging biometric technology which involves people being identified purely through the analysis of the way they walk

Aquaculture

Aquaculture and fish farming is an important and steadely growing industry in Norway. There is a need for developing more accurate, secure and sustainable methods for monitoring and measuring fish in cage farms. 3D Motion Technologies are tailoring our product to determine the size, shape and movement of 3D objects under water: points, length and height of a fish. The movements can be visualized in real time. The data produced from our system can be used to ie:

• biomass-estimation
• detection of salmon louse
• visual inspection of fish in a cage farm.
• analysis of fish movements to determine when to stop feeding, or to detect at an early stage stressfull behaviour of the fish

Generally, we can use the data both as an answer other data can copy or be analyzed against, and as a real-time analyzer of the data against some answer.
