UK’s Oxford robot car is here

I guess English scientists and engineers don’t like to be outdone by their American counterparts so after many years of hearing constantly about Google’s rapid development of self-driving cars, a team from Oxford university recently unveiled their very own robot car. And they make some very big claims about the new vehicle’s capabilities compared to… Read More »

A cheap stereo vision camera

Stereo vision cameras have certainly not gained wide adaptation in robotics research to the extend that time-of-flight sensors such as laser have. Part of the reason is the fact that the slower computers of the past have always made it difficult to deploy real-time machine vision systems for real-time robotics. Another has to do with… Read More »

Driftnet: Stereo vision art display

The Squidsoup crew, Anthony Rowe, Gaz Bushell and Ollie Bown, has put together a very interesting and entertaining display blending computer vision and art. The art display, Driftnet, gives people the ability to fly like a bird in a virtual environment. Driftnet depends on a Point Grey Research Bumblebee stereo camera to track a person… Read More »

Improving stereo vision with monocular cues

Stereo vision is an essential component for any mobile robot. The most popular stereo vision systems available today estimate the depth of points by finding matches between two (or more) spatially separated cameras and performing triangulation given known camera parameters. This correlation-based stereo algorithm is easily implemented in real-time on traditional CPUs or specialized FPGAs.… Read More »

Point Grey Research releases the Bumblebee XB3 multi-baseline stereo camera

Point Grey Research has finally introduced a new stereo camera with a wide baseline. Actually, the new Bumblebee XB3 has two baselines. The XB3 has 3 CCD cameras but it is not a trinocular stereo system similar to the company’s Digiclops camera. The 3 cameras on the XB3 are configured in a line providing stereo… Read More »

Tyzx’s DeepSea G2 3D vision system

As computers are becoming faster every year and computer vision research is making huge progress on new algorithms on a daily basis, 3D vision systems are starting to take their place in consumer applications. For example, stereo vision can be used in cars to detect other cars on the road or pedestrians; such information can… Read More »

Autonomous exploration with a vision-based mobile robot

In recent years, the vast majority of mobile robots have been constructed to rely heavily on a laser sensor for perceiving their surrounding environment. Laser is very accurate when it comes to measuring the distance to objects making it possible for mobile robots to navigate and map large and highly dynamic environments. On the other… Read More »
