Hardware products that SICK make has configuration parameters such as exposure time and frame rate. These parameters usually have some functional relation to each other.
Normally we express numerical parameters as integers or floats in program code. The relation between these parameters is also expressed as functions in program code. The function between two or more numerical parameters may interchanged, depend on choice made on enumeration parameter, here called function switch.
Each parameter usually also has a minimum and maximum value that is affected by the value of other parameters. With many parameters, their current value, min and max values, bidirectional relations to other parameters and function switches, software code quickly become complex and numerical consistency become hard or impossible to uphold.
The master thesis work focuses on the following
Investigate if it is possible to construct a general, theoretical system and prof-of-concept software implementation of it, to express relation graph between floating point parameters in such way that bidirectional numerical consistency is kept between parameters. Further, investigate if it is possible to choose algorithms in such way, that this system can be run on somewhat restricted embedded device.
The system should…
Suggested path forward
The hypothesis is that numerical consistency to a large degree can be upheld, if functions only are specified in a single direction in a relation. However, since we still want to have a bidirectional relation without specifying the inverse functions, the functions used need to be monotone in the legal range of the input parameters. For calculating the input value of a function, given the output value, a root-finding algorithm like bisection can hopefully be used.
Prerequisites
Computer science with focus on algorithms and numerical methods.
