New technology could make your dog a motion capture movie star
Other animals have also been captured using the method, including horses, cats, lions and gorillas

From reproductive rights to climate change to Big Tech, The Independent is on the ground when the story is developing. Whether it's investigating the financials of Elon Musk's pro-Trump PAC or producing our latest documentary, 'The A Word', which shines a light on the American women fighting for reproductive rights, we know how important it is to parse out the facts from the messaging.
At such a critical moment in US history, we need reporters on the ground. Your donation allows us to keep sending journalists to speak to both sides of the story.
The Independent is trusted by Americans across the entire political spectrum. And unlike many other quality news outlets, we choose not to lock Americans out of our reporting and analysis with paywalls. We believe quality journalism should be available to everyone, paid for by those who can afford it.
Your support makes all the difference.Researchers from the University of Bath have developed technology that would allow people to digitise their dogs.
Such an application could be used for a number of purposes, such as assisting vets in diagnosing issues walking and monitoring their recovery.
It could also be used for more entertaining reasons, such as putting digital representations of dogs into movies and video games – without constant use of motion capture suits or expensive equipment.
Computer scientists digitised the movement of 14 different breeds of dog, including lurchers and pugs, who were residents of the local animal shelter.
The motion capture suits, made especially for dogs, were filmed doing a range of movements as part of their activities.
They then created a computer model which could accurately predict and replicate the poses of dogs, capturing all the vital information without the dogs wearing the suits.
Instead, the researchers can use a RGBD camera. These are cameras also capable of recording depth alongside the red, green, and blue colours in each pixel that standard cameras photograph.
These cameras can cost approximately £100, while even low-budget motion capture suits can cost as much as $2,500 (approximately £2,000).
“This is the first time RGBD images have been used to track the motion of dogs using a single camera, which is much more affordable than traditional motion capture systems that require multiple cameras,” PhD researcher Sinéad Kearney said.
“This technology allows us to study the movement of animals, which is useful for applications such as detecting lameness in a dog and measuring its recovery over time.”
“For the entertainment industry, our research can help produce more authentic movement of virtual animals in films and video games. Dog owners could also use it to make a 3D digital representation of their pet on their computer, which is a lot of fun!”
Other animals have also been captured using the method, including horses, cats, lions and gorillas.
The researchers aim to extend this database further to make the results more accurate, as well as making it available for non-commercial use.
Professor Darren Cosker, director of the motion capture centre, said: “While there is a great deal of research on automatic analysis of human motion without markers, the animal kingdom is often overlooked."
“Our research is a step towards building accurate 3D models of animal motion along with technologies that allow us to very easily measure their movement. This has many exciting applications across a range of areas – from veterinary science to video games.”
