London-based engineering and design agency Ivmech Mechatronics and Innovation has designed a Raspberry Pi accent that delivers sensor fusion between a thermal imaging sensor and a visible-light digicam — merging the 2 right into a single view.
“The PitFusion is a cutting-edge dual-camera module developed for the Raspberry Pi, combining a thermal imaging sensor (MLX90640) and a Raspberry Pi [compatible] digicam [module] right into a single, compact system,” Ivmech Mechatronics explains of its creation. “This progressive module is designed to supply customers with the flexibility to seize each thermal and visible photos concurrently, opening up a variety of purposes in fields comparable to automation, robotics, safety, and environmental monitoring.”
Thermal imaging sensors are designed to measure temperatures at a distance — appearing like a non-contact thermometer, however somewhat than taking a single spot measurement capturing readings over a grid and deciphering them because the acquainted “thermal imaginative and prescient” imagery the place, utilizing a normal “iron” coloration scheme, scorching issues glow pink, yellow, or white, and chilly issues are blue or black. A visual-light digicam, equally, captures a grid of sunshine and coloration measurements that may be considered as a picture — and the PitFusion works to mix the 2.
The concept of mixing thermal imaging with visible-light imaging is not new: loads of business thermal cameras do the identical, sometimes as a manner so as to add element to the usually low-resolution thermal view. The PitFusion, although, is designed to be used with the Raspberry Pi household of single-board computer systems — and targets these trying to play with thermal fusion imagery on a funds.

The system relies on a 5 megapixel visible-light digicam able to capturing imagery at a decision of as much as 2,592×1,944. Subsequent to the visible-light digicam is the thermal sensor, a Melexis MLX90640 — chosen for its low value and with a considerably restricted decision of 32×24 for 768 complete readings updating at 32Hz. The low-resolution thermal information is streamed to the Raspberry Pi over the I2C bus, then scaled as much as match the decision of the MIPI Digital camera Serial Interface (CSI)-connected visible-light digicam — displaying a fusion of the 2.
Ivmech Mechatronics is taking orders for the PitFusion on its web site at $120.10 plus delivery, a value that displays the low decision of the thermal sensor; the corporate has additionally revealed supply code Python-powered supporting software program on GitHub beneath the reciprocal GNU Basic Public License 3, with the promise that schematics and board layouts information will comply with sooner or later.
