The University of Canterburys Mechanical Engineeringexperts are among the Kiwi innovators battling againstCOVID-19.<\/p>\n
While commercial devices for crowd feverdetection exist, the global pandemic has made them hard tocome by. The CacophonyProject and2040 developed low-cost smart thermal camera systems fortracking the predators that threaten New Zealands nativebirds, and have been pivoting the technology to meet thisurgent need.<\/p>\n
Working with the University ofCanterbury, Callaghan Innovation, and the AucklandBioengineering Institute with testing, calibration andwriting for the instruction manual, they have repurposedtheir technology for crowd fever scanning at a safedistance. The system can measure forehead temperature to+\/-0.5C without a human operator.<\/p>\n
UC mechanicalengineers JulianPhillips, Lecturer TimGiffney and Professor MarkJermy have developed a temperature reference to give aconstant check calibration of these devices. The devices areunder trial and hoped to be implemented shortly to curb thespread of the virus.<\/p>\n
If thermal imaging cameras aredeployed for temperature screening, this stable temperaturereference can help with accuracy. We hope this stablein-frame temperature reference could be useful as a simple,rapidly deliverable approach, UC Engineering Lecturer TimGiffney says.<\/p>\n
By putting a stable temperaturesource in view of the camera, the system can continuouslycheck its reading, and make adjustments, UC Engineeringtechnician Julian Phillips adds.<\/p>\n
The main challengein developing the reference was coming up with a design thatcould be rapidly built with minimal resources, and fromlocal supplies as international freight is at an almostcomplete standstill.<\/p>\n
Fortunately I have quite awell-equipped workshop at home, needing only a few items tobe obtained from UC, Phillips says. In January Itravelled to Tonga to support a team of ourUC biomedical engineering students working on donatedmedical equipment. The experience of working underconstrained resources was good preparation for working underlockdown a similar level of flexibility and tenacity isrequired to get the job done.<\/p>\n
About 30 soldiersfrom Burnham, as well as New Zealand Police officers, wereused to test and calibrate the cameras. To help control thespread of COVID-19 it is envisaged the cameras will be usedat airports, hospitals, supermarkets and otherworkplaces.<\/p>\n

Objects at close to human bodytemperature only emit a very small amount of radiated heat,which is difficult to detect in the camera sensor. Thismeans it is not easy to make an accurate thermal camera thatis insensitive to external conditions.<\/p>\n
Comparingthe temperature of a surface to our reference at knowntemperature is less difficult. This could allow a widervariety of thermal imaging cameras to be used, which wouldbe useful in case of shortage.<\/p>\n
The internalcorrection routines of some cameras can also causeinconsistent readings, which our method could helpcontinuously calibrateout.<\/p>\n
