Virual Oral Question and Answer


IEEE/ICACT20230138 Question.1 Questioner: phamdinhlam@kyonggi.ac.kr 2023-02-19 오전 11:38:50	IEEE/ICACT20230138 Answer.1 Answer by Auhor sdk@etri.re.kr 2023-02-19 오전 11:38:50
The distance between two ships is calculated in the same 2D space. But in fact, different cameras will give different distances with each different angle of view from the two ships. What happens when two ships cross each other, going parallel to the camera's perspective? like letter x, letter T,...	Prior to the experiment, we derived px and py by measuring the horizontal and vertical distances from the simulation camera viewpoint, and used them for the experiment. As the questioner said, due to the difficulty of measuring the vertical distance, the error appears larger in the vertical measurement than in the horizontal measurement.
