trying to research into LiDAR technology a little bit, get a kind of understanding of it

i dunno, there is something that i really enjoy about the imagery of these point maps
i guess it gives this feeling of how a computer could see - this mixture of a heat map/point map
everything is constructed through these points, there's a strange atomisation of everything, the way a road marking is viewed is the same as how a person, or a vehicle is realised
it's a kind of holistic view of the world
and with this video - the manipulation of the view point gives a visualisation to the difference of the method of capture - because i think there's a pull to see this as a type of photography - and in a way you have this development process of the image, but maybe a question arises in thinking about this in Bathes terms of studium and punctum - could a 3D scan like this have a punctum? or maybe that is kinda the challenge of how you make sure this technology doesn't only become situated as just a tool
because it maybe feels easier to assign the cultural position of the studium to an image/scan created in this way - and it almost feels double layered in its studium at the moment because of the relative newness of the technology
what's maybe interesting is that everything it is picking up is relative to something existing on different layers (textured)
looking at the comparison between these two images, you can see that the LiDAR has registered the STOP markings on the tarmac, raised painted marking, versus the stop sign that only shows the shape, with any printed marking being lost
to capture something with this - you need an element of depth - without depth you are left with a plain front
for a minute i was thinking that this maybe lends itself more to looking at natural forms, as there is much more likely to be elements of texture, less flat surfaces, but i guess in thinking about it more, i would be really interested to see the level of detail LiDAR could capture - because realistically even something we visually perceive as being smooth, is most likely going to have at least small imperfections
there's something about the contexts that this technology is being presented in by the creators - obviously it is very much linked to notions of automation, self-driving cars/smarter cars, and then in this warehouse setting - and in this warehouse setting, i guess it makes me think of maybe the above point of how does it register smooth surfaces? does there have to be an integration of LiDAR to allow some form of automated device/vehicle to move around the space, then another kind of barcode scanner that registers an item for collection - i think the thing is that the potential of technology like this for examination of spaces, whether that be natural sites (woodlands, rainforest, deserts etc.), and also for examination/recreation of historical sites feels very exciting, but obviously there has to be this push towards business, ways of seemingly making things easier, removing the potentiality of human error - gradually phasing out workers
"The OS1 now outputs fixed resolution depth images, signal images, and ambient images in real time, all without a camera...The OS1 captures both the signal and ambient data in the near infrared, so the data closely resembles visible light images of the same scenes"
