Thesis - Performance of custom compression algorithm in FPGA



Apply by



High speed laser triangulation cameras from SICK can produce a lot of 2D and 3D image data continuously transmitted over ethernet. The image data has some characteristics to take advantage of in compression and the cameras has some embedded device restrictions that has led to the investigation of a custom compression format.

A proof-of-concept implementation of the compression format is already done as a C++ program on PC.  The data compression has some degree of freedom in how to utilize the compression format to its advantage and the heuristics to use when encoding. The task is to investigate if the custom compression format can be adapted for implementation on FPGA.

The bachelor thesis work focuses on the following examples of research questions

What trade-offs need to be done compared to the C++ implementation?

What aspects affects compression speed and space requirement on FPGA?

Given the tradeoffs made, how does the FPGA-implementation perform compared to C++ implementation when looking at compression ratio?
