00:00We use three ways to digitalize the cave, one is the three-dimensional laser scanning machine that we hold in our hands.

00:27The main task is to obtain the detailed three-dimensional model of the whole cave.

00:31The other is the three-dimensional laser scanning machine that is used in combat.

00:34The main task is to control the large area of the cave.

00:37The data that it scans out is the electron data.

00:39In the later stage, we can also generate this kind of three-dimensional model for it.

00:43The other is to take pictures.

00:45The main task is to obtain the textual information of the whole cave.

00:47Because the data from our laser scanning machine is colorless,

00:51so we take pictures to obtain its color information.

00:54The three kinds of data are integrated with each other.

00:56In the later stage, they are integrated together to form a colorful three-dimensional model.

01:00The difficulty is that this thing is a fine grain.

01:03In fact, it is the same as a paper brush.

01:05When it is scanned, it does not mean that it can be stepped on immediately.

01:08You may not be able to scan it with bare feet.

01:10It needs to be scanned and processed repeatedly.

01:15The strongest one I have scanned so far is the 19th cave.

01:19This cave is relatively large in volume.

01:21It also has two holes.

01:23It is equivalent to three caves.

01:25At that time, it took us about two and a half months to collect the official website.
