Ghost Drone

The Ghost Drone is a wind and rain resistant Indiegogo project drone aimed at filmmakers, photographers, sports enthusiasts, travelers and adventurers, GoPro owners and first time and experienced drone pilots.

It is controlled by a smartphone app (either iOS or Android operating systems) where you can click on a map and the drone will go to that position; the map can be downloaded in advance. The app also has a number of one-click commands including take off, hover, return and land. Two sliding bars can be used to control the height and orientation of the drone; while another two control the camera gimbal with one tilting the camera up and down while the other pans it left and right. It’s micro control feature allows more precise movement of the drone over small distances. The Auto-Follow mode keeps the drone following the smart phone. If the drone exceeds 0.6 mile limit or the signal is lost it will return to its place of origin.

The app communicates with the drone via a G-box system, with the app communicating with the G-box via bluetooth while the G-box communicates with the drone via a wireless radio.

Other developments at higher Indiegogo targets include integration with a waterproof smartwatch and controlling the drone by tilting the smartphone, while obstacle avoidance will be available in future versions.

  • Up to 20 mins flight time with the gimbal
  • 10 mph (restricted) flight speed
  • Up to 0.6 miles control distance
  • Wind resistance up to 21 knot (11m/s)
  • iOS and Android apps
  • Propeller protectors

The Ghostdrone comes in 3 seperate versions, only two of which have a camera gimbal:

  • Ghost Basic (£430) – No camera gimbal.
  • Ghost Aerial (£550) – 2-axis gimbal designed for GoPro and similar cameras.
  • Ghost Aerial Plus (£559) – 2-axis gimbal and Ehang Sports camera.

An RC controller can be purchased for an extra $99. Another optional extra are prop guards to protect both the system and what is may be flying near, and photos on the site seem to suggest that the mini legs attached to them can be used to replace the main landing gear, this would allow a greater field of view.

Potential
The Ghost Drone is marketed as the easiest done to fly, and the flight controls within the app will certainly enable many autonmated movements with one button click.

The propellors of the system are pointing down rather than up (unlike other systems), this is believed to provide more stable flight.

The fact that the Ghost Drone is wind and rain resistant means that is can be used in conditions that would ground other systems.

As with other systems, the follow-me technology will allow the easy recording of video site tours.

The Ghost Drone comes with an SDK (Software Development Kit) which has already been used by one of the users to create voice interface which can be used to control the drone.

Limitations
The Ghost Drone is limited to the abilities of smaller cameras.

The system does not come with an RC controller, although it is an optional extra for $99.

Although you can purchses prop guards the manufacturer suggests removing tham during filming as they destabilise the system in flight.

Kodak PixPro SP360 Action Cam

The Kodak PixPro SP360 is an action camera aimed at the extreme sports recording market.

It is able to record 360º 10MP photographs and Full HD 1080p Video using its curved lens. Using the Pixpro Remote Viewer App it connects to other devices with iOS, Android or Windows operating systems using Wi-fi and NFC (Near Field Communication) allowing both control of the camera and viewing of the images/videos. The images/vidoes can be viewed in a number of different modes – ring, dome, front 180º and rear 180º, 360º panorama and globe. The system also has motion detector sensor which starts recording when motion is detected.

Much like the GoPro camera the system comes with a number of accessories for attaching it to different devices as well as a waterproof case which aare available in the different bundles.

The PixPro SP360 costs $349 for the Explorer bundle for entry-level and the Aqua bundle for watersports and $399 for the Extreme Accessories bundle.

Potential
The camera is able to record much more than a standard camera without the requirement for multiple cameras and the images/videos created can be viewed/exported in a number of different modes. It is water resistant, can be attached to a UAV or a person allowing a wide range of recording possibilities.

Limitations
Although the system can record a 360º view images/videos with the camera pointing upwards it is only able to record a 214º images/videos while pointing towards a subject. The distortion of a domed lens may also impact on the quality of the results.

GoPro HERO

The GoPro HERO is a new budget camera in the GoPro range. It takes 5MP (mega pixels) photos which can be recorded up to 5 frames a second and records video at 1080p30 and 720p60. With its rugged case it is waterproof to 40m.

The interface has been made easier with the new QuikCature mode which allows the user to power on the camera and start recording by pressing a single button. Pressing once records video, while holding the button down for 2 seconds starts to capture time lapse photos.

The GoPro HERO costs £99.99.

Potential
The GoPro HERO has much of the same potential as the GoPro HERO4 which can be read here.

At only £100 its potential for budget wearable technology in archaeology is enhanced greatly, with the cost of 3 GoPro Heros being less than 1 GoPro Hero4.

Limitations
Up until now one of the major limitations of the GoPro has been the price, but with a GoPro costing £99.99 this drawback has been removed.

There are limitations to this budget model though, the camera is only 5MP as opposed to the GoPro HERO4 which is 12MP, which is quite a low level of recording for a modern digital camera. It will limit the amount of information recorded in a photograph, and hence any 3D models created from the results.

GoPro HERO4

The GoPro HERO4 is a new camera in the GoPro range, it consists of two separate models, the silver and the black.

Silver

The silver model includes a built-in touch-screen display, previously this had been available as an extra which connected to the back of the camera, the black model does not come with this.

It captures photographs with its 12MP camera at speeds up to 30fps and records video at 1080p60 and 720p120.

Black

Professional Video up to 4K30

It captures photographs with its 12MP camera at speeds up to 30fps and records video at 4K30, 2.7K50 and 1080p120.

Both models have built-In Wi-Fi + Bluetooth allowing connection and control from other devices using the GoPro App, Smart Remote2 and more.

With their rugged case they are waterproof to 40m.

The silver version of the camera is £289.99 while the back is £369.99.

Potential
The GoPro camera was designed with the extreme sports industry in mind, but it has since find a place in a number of other disciplines.

The size, weight and portability of the GoPro camera has meant that is had become the mainstay of the UAV (unmanned aerial vehicles) industry with the camera becoming standard on many quadcopters. The user can see what the camera sees by either using the on-board wi-fi and an app on tablet computers or phones; or a fpv (first person view) system which can be sent wirelessly to either a video monitor or video goggles. Motorised gimbals can be used to both, stablise the camera to remove any shake caused by the UAV, and to change the direction the camera is pointing in mid flight.

The GoPro also has great potential as wearable technology in the trench:

  • The camera comes with a number of mounts out of the box, including ones that can attach to hardhats, but other mounts are available including a chest harness. These could be used to record the excavation process by attaching GoPro camera to the archaeologist excavating; the video could be used to record video but the individual video frames, or photographs, could be used to create a 3D photogrammetry model of the excavation. The combination of head and chest mounted camera may provide enough images to make an accurate model of the excavation. The rugged plastic housing can protect the camera from anything that it comes across in the trench.
  • If a complicated or important excavation was being undertaken or an important artifact was being lifted the excavator could have a live conference with an expert who could advise them on the best way to excavate it.
  • Experimentation with aspects of wearable technology has been undertaken on the Portus Project in Italy under the auspices of the University of Southampton.

The use of the GoPro is not limited to a single camera, the Dual HERO System is a case that allows two GoPro camera to be put side by side which allows 3D footage to be created using the GoPro Studio editing software.

GoPro Dual HERO System

The 360heros series of GoPro mounts clips a number of cameras together allowing spherical video recording with up to 14 GoPro cameras, the videos recorded can be stitched together in video stitching software to create immersive 360˚ videos. Mounts are available for everything from the top of helmets, to UAVs, underwater recording and even for recording 360˚ 3D with 14 GoPro cameras.

The system can record immersive videos on the ground, in the air and underwater which can viewed in a video player online – http://video.360heros.com/website/users/webplayer/videodetails.php?vid=59

The Freedom360 provides a similar system.

A GoPro has even been attached to a shovel while archaeology is being undertaken – https://www.youtube.com/watch?v=ht0RR94O9jY&feature=youtu.be

It has been used in underwater test of sfm (structure from motion) – http://arc-team-open-research.blogspot.co.uk/2013/03/extreme-sfm-underwater-archaeology.html

Limitations
The HERO4 Black provides the user with a highly portable camera capable of recording 4K video, it does however come at a high price which limits the potential of using multiple cameras in an immersive recording system, the cheaper HERO does provide this opportunity however.

Raspberry Pi Camera Module

Although the Raspberry Pi itself comes with no digital recording capabilities out of the box, for another £25 the camera module can be purchased and used to record video at 1080p30, 720p60 and VGA90 modes and images can be captured with its 5 megapixel camera.
