Anonymous Traffic Survey Cameras

Man­u­al Traf­fic Sur­veys Many peo­ple in the UK may be famil­iar with see­ing groups of peo­ple, or some­times a parked vechi­cle, clear­ly dis­play­ing a sign say­ing ‘Traf­fic Sur­vey.’ These peo­ple are employed to keep a tal­ly of the num­ber of vehi­cles using a road, and the types of vehi­cles. This infor­ma­tion is impor­tant for plan­ning … Read More

Sony Noise Cancelling Headphones as Binaural Microphones

Sony Noise Cancelling Headphones as Binaural Microphones

My Sony smart­phone has an unusu­al TRRRS (Tip-Ring-Ring-Ring-Seal) con­nec­tor, allow­ing it to use very rea­son­ably priced noise can­celling head­phones that have an extra micro­phone in each ear­phone. I found that the Sony app Sound Recorder allows select­ing record­ing direct­ly from these two micro­phones, and are great for bin­au­r­al record­ing, and I gave it a go walk­ing … Read More

Open Bionics robotic hand for amputees

Open Bionics robotic hand for amputees

“A pro­to­type 3D-print­­ed robot­ic hand that can be made faster and more cheap­ly than cur­rent alter­na­tives is this year’s UK win­ner of the James Dyson Award.” (BBC News link) This is a fan­tas­tic idea, which has so much val­ue to peo­ple with­out limbs. Bion­ic pros­thet­ics can cost up to £100,000, and £30,000 for a sin­gle hand. The 3D-print­­ed … Read More

Project Tango and Visual-Inertial Localization

This project enti­tled “Large-Scale, Real-Time, Visu­al-Iner­­tial Local­iza­tion” is inter­est­ing, using Google’s exper­i­men­tal ‘Tan­go’ hard­ware to improve real-time track­ing of loca­tion and posi­tion. The hard­ware is a tablet com­put­er with a motion track­ing cam­era, a 4 megapix­el 2µp pix­el cam­era, inte­grat­ed depth sens­ing and a high-per­­for­­mance proces­sor. This equip­ment aids in tasks like scan­ning rooms. A … Read More

Smart scanning technology detects early signs of potholes

Smart scanning technology detects early signs of potholes

Inter­est­ing work by a team led by Not­ting­ham Trent Uni­ver­si­ty on mak­ing a mobile scan­ner that can detect ear­ly signs of pot­holes. It uses con­ven­tion­al cam­eras, 3D scan­ners and com­put­er vision to detect ‘rav­el­ling’. Mov­ing this around at traf­fic speed mount­ed to a vehi­cle, and com­bin­ing it with GPS and a suit­able log­ging sys­tem, it … Read More
