World Launch of CrocSpotter Ai Algorithm

Little Ripper drone flying in North Queensland with live video stream running revolutionary CrocSpotter Ai Algorithm to Brisbane – World of Drones Congress.   Little Ripper drones is working with Amazon Web Services (AWS) to produce an ultra low latency of l second high definition video stream running Artificial Intelligence (Ai) analytics via a drone. The companies have been working together for the last 8 months to reduce the latency of the algorithm. CrocSpotter is one of 5 ’spotter’ Ai algorithms developed by The Ripper Group and its other technology partner, University of Technology Sydney.

On Thursday, September 26 at 10.30 am, a live video stream from a Little Ripper drone flying near Cairns in Far North Queensland, took place. The CrocSpotter Ai Algorithm function from the Little Ripper drone will go via AWS on to the big screen at the World of Drones Congress in Brisbane. This was the first time anywhere in the world a drone running CrocSpotter Ai Algorithm will be seen positively identifying Crocodiles and streamed live publicly.

There was be two teams at different locations operating this world breaking undertaking on Thursday. One at the Mowbray River just outside of Cairns in North Queensland from which the Little Ripper drone will fly over a lagoon in surveillance of crocodiles, and the other team 1691 kms away at the World of Drones Congress in the Brisbane Convention Centre.

Little Ripper drones carry the Ai Spotter as part of the drone’s payload with the on board video. As the video streams live from the Little Ripper drone to the pilot on the ground, the algorithm operates by ‘washing’ the video and alerts the pilot to a possible threat below. The threat is immediately highlighted by a flashing red box around the animal, and draws the pilot’s eyes directly to that part of the iPad he uses to fly to drone. The algorithm has a 93% accuracy of identification, and the naked eye between 16-19%!

The first Ai algorithm was SharkSpotter. It was developed in 2017 in response to a series of shark attacks in Northern NSW, with the aim of fast and efficient identification of a threat to swimmers for lifeguards.

Surf Life Saving Queensland, with funding support by the Queensland Government approached Little Ripper to develop a similar Ai algorithm to SharkSpotter for detection of crocodiles, in response to a series of incidents and increased sightings in 2017/2018 in North Queensland, Australia.

Little Ripper
Ben Trollope, CEO of The Ripper Group said, “The Ripper Group have a suite of Ai Algorithms operating and in development. The Ripper Group operates one of the world’s most advanced fleet of search and rescue drones with the Little Rippers. A Little Ripper drone performed the world’s first rescue by a drone at Lennox Head in NSW in January 2018, dropping an inflatable pod to save 2 teenagers in massive surf.”

“Today’s revolutionary unveiling and live stream comes in a tripartite cooperation between Little Ripper and their technology partners University of Technology Sydney in developing CrocSpotter, and AWS in reducing the video streaming of CrocSpotter Ai to a latency of almost 1 second for first responders. Currently, to run the CrocSpotter Ai algorithm through the Little Ripper on board video, it has a latency of 10-30 seconds.”

The same team that brought you SharkSpotter, the Ai-powered drone-based technology for protecting our beaches and keeping our wildlife safe, have developed the next breakthrough software for detecting crocodiles in Far North Queensland – CrocSpotter Ai.

University of Technology Sydney (UTS)
UTS researchers in the Faculty of Engineering and IT (Professor Michael Blumenstein and Dr Nabin Sharma) have continued their fruitful collaboration with The Ripper Group to develop cutting-edge Ai software deployed via drone on AWS for detecting crocodiles from Mission Beach to Port Douglas. The Queensland Government is keen to see the roll-out of the technology as part of their CrocWise programme to prevent crocodile attacks, but also to develop a better understanding of our crocodile populations from a conservation perspective.

The UTS team have used an Ai technique called Deep Neural Networks to detect the crocodiles via a smart camera from the flying Little Ripper drones, and have deployed the technology in the cloud. Professor Michael Blumenstein who is part of the UTS team said that the speed of the cloud-based Ai enables the crocs to be spotted in real-time, which is a world-first and a technological breakthrough given the very low latency.

“The technology enables crocodiles to be detected in complex environments including murky and muddy waters in both wetlands and the open ocean. This is the first time that this sort of animal detection drone technology has been deployed via a high-quality video stream at ultra-low latency with the Ai producing a greater than 90 % accuracy to detect crocodiles,” Dr Sharma said.

Amazon Web Services (AWS)
The Little Ripper drone uses Amazon Elastic Compute Cloud (Amazon EC2) instances, to support its online AI image-processing application. To accommodate its increasing image storage needs, the drone uses Amazon Simple Storage Service (Amazon S3) to ingest the aerial images each day. Amazon S3 is highly scalable and reliable, and the drone uses it to store aerial images as raw data.

Elemental Live produces video streams, which ensures uninterrupted video delivery to end users facing high network traffic or bandwidth constraints. It powers the TRG app to create content for a variety of viewers and devices. Elemental Live enables the low latency, which allows the video captured via the drone to be streamed to the app almost in real-time.

Ben Thurgood, Head of Solutions Architecture NSW and QLD, AWS Public Sector in Australia and New Zealand said, “The low latency video stream powered by AWS is critical to ensure information is quickly transmitted to pilots powering the drone. The cloud’s scalability has allowed The Ripper Group to innovate new ways to save lives and protect native crocodile wildlife. Organisations in Australia and around the world continue to leverage the breadth and depth of AWS to deliver innovative citizen services, and address some of the biggest community needs.”

The Ripper Group have been in partnership with since 2016 to maintain 17 remotely piloted aircraft systems (RPAS) across New South Wales and Queensland.

Craig Menerey, Regional General Manager, Queensland, said, “ Little Ripper drones have played a pivotal role in shifting the way drone technology is used to protect local communities by identifying sharks, marine life and other hazards, and supporting rescue services in emergency situations.

” is proud to support the evolution of drone technology to help save lives in coastal and in-land waterways across Australia, and build on our 45 year national partnership with the Lifesaver Rescue Helicopter Service who have conducted more than 80,000 missions nationally to date,” Mr Menerey said.
