Indirect ToF is an integrating approach (accumulate numerous pulses and read out several subframes to compute depth image) conversely to event sensing being based on time-continuous photocurrent. I'm neither able to see how indirect ToF shall be able to withstand intense ambient lighting conditions - it's universally appreciated that they're really not. Outdoor operation under full sunlight has always been an issue for ToF. Conversely, event sensors work on time-continuous photocurrent and are sampling the temporal changes only. I am not aware of a work illustrating limitations of event sensors at strong illumination. Quite the opposite actually, if you look at dynamic range measurements of event sensor publications, they have a lower cutoff where the signal is too weak to reliably create events without excessive latency, but most people seem to struggle to actually measure where these devices clip. I would appreciate if you could provide references and more elaborate explanations to support your view.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-19092890.post-62374637305890818482022-02-14T17:30:28.150+02:002022-02-14T17:30:28.150+02:00Cool publication!
