Investigate camera undistortion performance and acceleration #4

Closed vainiovano closed 2 weeks ago

vainiovano commented 3 weeks ago

Investigate: could a GPU or other forms of hardware acceleration be used?

Spent: 1.5 h. Performance is pretty bad, but needs to be tested more. No CUDA support included, but might not be that difficult to implement.

Spent: Another 1 h. Figured out how undistortion should actually be done. Measured CPU and GPU performance and created slides.

Performance on my gaming PC: around 700µs for undistorting on CPU and 17µs on GPU
