[REL] TMA / 4-bearing method general line detector & solver v0.1

Hi, this is another fun program that I converted from the original open-sourced Dangerous Waters TMA project.

The core technology behind it is to use computer vision to detect lines in an image and do automatic TMA directly on those lines. The program outputs target course and shows target position/trace directly on the image, but you'll need to calculate the speed yourself.

You're required to record bearing using the same time interval but does not need to be stationary when taking the first 3 bearings. Hopefully this will make TMA or other hydrophone methods like 3/4-bearing method extremely easy in any sub sims.

The instructions are provided in the download section: https://www.subsim.com/radioroom/dow...o=file&id=5605

Happy hunting!
