REMOTE SENSING WORKSHOP

RUN BY: SIMON WITHERS

This workshop was an introduction to Remote Sensing by using Photogrammetry, one of several Remote Sensing technologies that include; 3D Scanning - LiDAR or SLAM scanning both terrestrial and aerial, terrestrial and aerial Photogrammetry, Ground Penetrating Radar and SONAR.

In the lecture Simon showed us a series of different scannings we can do.

We also saw examples of scanings that go through buildings and can get different sections of the building.

1. As an excersise we had to go out and take several pictures that we would later one add

As a part of an exercise we had to go out and take several pictures that we would later one add them on metashape and create a scan we had to make sure the picture were jpegs.

After opening metashape app we had to add the photos into the app.

3 we selected aligh photos from the workflow setting.png

We selected align photos from the workflow setting.

Once the photos are aligned they should look like this.

Select build dense cloud via workflow setting

After build dense cloud the model should look like this.

Select build mesh tool from the workflow settings

Scan should look like this following the above steps

As part of a different exercise we had to go out and scan elements. For these scannings I used the app called Polycam.

This is how the first scanning turned out

I experimented with the app by scanning different parts of our campus

I tried scanning to detail this bench since it was smaller than the previous scannings and it could catch more details than the walls and the buildings.

The result was pretty good as it captured many details.

Although the quality of this scan does not seem great, I found the concept of scanning very fascinating so I was trying to scan the route as we were walking around the campus.

SITE VISIT SCANNINGS

I used the technique taught during my site visits for the design module.

For this scanning I used scaniverse.

Using Scaniverse app I scanned this area which was quite large, but it did manage to scan details like the rubbish in the water.

I also scanned smaller areas which looked very detailed via scaniverse app.

For this scanning I used Polycam. The distances were a bit long and it dod not manage to capture everything in detail.
