Mission Report: 3D Scan and Data Collection

 Mission 1: 3D object mapping mission

(Submitter: Jinwook & Joel)

 

Weather conditions

●       Cloud Cover: Clear

●       Wind Direction: NE to SW

●       Wind Speed: 4 mph

●       Temp: 72° F

 

After we checked the potential hazards in the street view of google maps and confirmed that there we could fly without problems, we got permission from LAANCE (Class D, 400 feet)

LAANCE APPROVAL: ALTTVJQZJU10

We made an emergency plan (if the aircraft looks unstable, land as soon as possible).

 

2D mapping mission with skydio 2 +

We flew the drone Sykio 2+ with 2D landmowing pattern and opposing grid lines over the area shown in the image below.

The intended scan area was constituted of 5 parking slots, the mission was originally planned to have a camera lens angle of 90 degrees for the first pass, 80 degrees for the second pass and a perimeter flight at 45 degrees.

However, when we set up the flight, we ran into a problem. The Skydio platform didn’t allow us to configure independently the camera lens angle of the first and second flight passes, therefore, both of the opposing grid lines passes were flown with the lens angle inclined to 80 degrees; the flight of the drone was also configured to fly the perimeter with the lens at 45 degrees, this parameter was configured successfully.

The altitude performed for the flight was 100.5 ft (about 30.6 meters), this altitude was enough to clear obstacles and still obtain high resolution pictures of the scan surface, additionally, we made sure to overlap the pictures by 80% from the frontal and lateral sides to get good quality images, resulting in a total of 31 pictures.

 

2D mapping mission with mavic 2 pro 90 degrees

We flew the drone Mavic 2 pro with opposing gridlines over the area shown in the image

The intended scan area was constituted of 5 parking slots, the mission was planned to have a camera lens angle of 80 degrees for opposing gridlines pattern

The altitude performed for the flight was 100.5 ft (about 30.6 meters), this altitude was enough to clear obstacles and still obtain high resolution pictures of the scan surface, additionally, we made sure to overlap the pictures by 80% overlap and sidelap to get good quality images, resulting in a total of 9 pictures.

 

 

2D mapping mission with mavic 2 pro 80 degrees

We flew the drone Mavic 2 pro with opposing gridlines over the area shown in the image below.

The intended scan area was constituted of 5 parking slots, the mission was planned to have a camera lens angle of 80 degrees for opposing gridlines pattern.

The altitude performed for the flight was 100.5 ft (about 30.6 meters), this altitude was enough to clear obstacles and still obtain high resolution pictures of the scan surface, additionally, we made sure to overlap the pictures by 80% from the frontal and lateral sides to get good quality images, resulting in a total of 8 pictures.

Mission 2: 3D model mission

(Submitter: Jinwook & Joel)

Weather condition

●       Temperature : 57F

●       Humidity : 70%

●       Visibility : 10mi

●       Windspeed : 10 mph from Sout

And then we checked the potential hazards in the street view of the google maps. We got permission from LAANCE (Class D, 400 feet)

LAANCE APPROVAL: ALT1M4F2O0B0

We made an emergency plan (return home, land as soon as possible if the aircraft looks not stable)

Car simulating an accident using 3D scan(skydio 2 +)

 

We didn’t have a car for this mission so we tried to borrow a bike from our friends but we couldn’t, so we tried to use the random car for this mission but it’s weird as well so we finally used a shopping cart instead of a real car near Walmart for this mission. We set 90 % for both overlap and 10.9 ft for the distance to surface to get better quality for pictures. as a result, we got 250 images for car simulating an accident.

 

Car simulating an accident using the 3D orbit scan function(mavic 2 pro)

We tried to use the 3D orbit scan function but we were not able to do it because the space was not broad for the scan. So, we used FREE FLIGHT and orbited the shopping cart manually.

Why we chose these areas?

Submitter: Jinwook

The reason why we chose the turf farm was turf farm is good for doing our first mission, we were supposed to do mapping mission with skydio 2 + and mavic 2 pro. the wide open parking lot is good for mapping missions.

The reason why we chose the walmart was we had to find another option to simulate car accidents. we don’t have our own car, so we had to use different one and we finally decided to use shopping cart instead of real car. we also found enough space near walmart for the mission.

Skydio 2 + vs Mavic 2 pro

Submitter: Jinwook

In terms of the controllers, the Mavic 2 controller is better than Skydio’s for us. the reason is we are still used to Mavic 2 pro so it is still easier for us to control it. I also could feel the controller of the Mavic 2 Pro is smoother than the Skydio 2 +

In terms of the batteries. Both of the drones offer a good flight time, but we were able to feel the DJI Mavic 2 Pro offered a longer flight time.

In terms of the platform, even though Skydio 2 is a smaller company than Mavic 2pro now, the platform of Skydio looks better for us. the skydio2 + platform appeared more sturdy. we didn’t take much time to get used to the studio because of the sturdy platform. I spent much time getting used to the Mavic pro platform honestly. I can say the Skydio platform is well-organized compared to the Mavic 2 Pro.

In terms of the scanning,  the scanning of Mavic 2 pro was simpler than Skydio 2. We didn’t spend much time setting up for the scan with Mavic 2 pro. All we had to do was select which type of mission and set the angle of the camera, front overlap, side overlap, and drone speed. However, in terms of scanning the Skydio 2 +, we spent much time to set up for the scanning. we set boundaries, pillars, ar observer and visual geofence as well as basic settings (overlaps and the angle of the camera). so we could feel even though it took more time, we could get more specific and better results in skydio scanning.
