Time alignment

[mjl-655]

As far as I know, the camera takes pictures at a slower frequency than the radar frequency. How do you time align the two data, by fusing a sequence of adc signals into a tensor that corresponds to an image? I saw that each sequence in the data set contained images and radars, and they were numbered and aligned. There are also some files that need to be used in the annotation process that I haven't found a way to generate, such as data_seq_ref.json, DOAPoints.csv. Can you tell me how to generate them to ensure that the entire annotation network works properly? I would appreciate a reply.
