Day 7: Scanning continues

by Dr. Mark Schuler • 2019, Research Phase

As I do more scanning — 108 scans so far — I marvel at the capability of the hardware while struggling with the challenges of the site. Heat continues to be a problem. If I scan in the early part of the day, I have harsh sun angles. If I scan later in the day, the heat can shut me down (the iPad actually) in about an half hour. I also wish I had worked more with the scanner in advance. To be effective in archaeology, the device needs an extendable pole for the tripod. These are just a few of the thing the field is teaching me.

Enjoy today’s scan of the structures southwest of the church…

Day 6: Scanning the Church Proper

by Dr. Mark Schuler • 2019, Research Phase

Today, two projects were my focus. First of all, using my chart of walls, I went systematically through the site reviewing and noting the interrelationships of the walls. This work is essential as I build the final report on sequencing.

Secondly, and more visually exciting, I began the scanning of the church complex. Had a little trouble with heat shutting down the iPad, but I am quite happy with the result:

Point cloud for the Northeast Church

As one zooms in, the detail is quite excellent. The cloud still requires some cleaning and geo-referencing. But the initial product provides the hoped-for basic data..

Amazing Scans…

by Dr. Mark Schuler • 2019, Research Phase

I returned to Sussita to refine the scanning techniques. When dealing with large spaces, I am discovering that the scans must be closer together. The software could not auto-register the scans; but I was able to be much more successful manually. The results:

Back to the field tomorrow. This is exactly the kind of data I was hoping to gather.

Scanning easy . . . registration, no so much …

by Dr. Mark Schuler • 2019, Research Phase

Today, I did trial scanning in the field. I went up to Sussita early to avoid the harsh sunlight, but there were no protective clouds. The scanning was easy. But the iPad had trouble registering the third scan. I did a total of sixteen scans around the perimeter of the main excavation area and in major spaces.

First scan operation

Back at my room on the kibbutz, I loaded the scans onto the laptop and had the same problem with auto-registration. Above is the output of my first attempt at manual registration. The cloud is quite messy and not well aligned. So, I have read up more on registration and am working on a second attempt. Weekends are helpful.

Day 5: Ready for scanning

by Dr. Mark Schuler • 2019, Research Phase

It took a week, but today we finished the cleaning of the NIP.

What has once been full of weeds and brush is now visible.

This weekend we will test our scanning processes. After some wall analysis on Sunday, the detailed scans will start on Monday. We look forward to the results.
