What is Thermographer?
Thermographer is a service that enables industrial workers, supervisors, and inspectors/auditors who use DAQRI Smart Helmet to generate detailed, real-time 3D thermal maps of their environment, equipment, and infrastructure. Through its use, you’re able to identify thermal anomalies and physical changes to worksites over time, as well as compare historical models to identify trends.
How does Thermographer work?
Thermographer uses the sensors, proprietary algorithms, and software built into DAQRI Smart Helmet to generate dense 3D models. No external sensors or equipment required. The thermal and depth data from the Helmet’s cameras and sensors, along with the user’s position and orientation data from DAQRI Visual Inertial Odometry (VIO) technology, enable the Thermographer service to generate a 3D virtual reconstruction of a wearer’s environment in real time, overlaid with thermal data both on the device and in the cloud. Thermographer is able to distinguish features and objects down to just a few centimeters in size. In many cases, we can actually tell the position of a switch based on the 3D model. Designed to work in industrial scenarios, it can map temperatures from -20 to 120 C, delivering optimal results at a range of 0.5–2.5 meters.
Why is Thermographer awesome?
Environmental mapping is a foundational technology of augmented reality, and a companion to our VIO. Combined, they can inform where you are and provide information about the world around you. Frequently used environments can be continuously updated and refined by multiple users for continuous improvement. Additionally, this service can run in the background, while other tasks are performed with DAQRI Smart Helmet. Thermal Maps can be used to detect thermal anomalies and physical changes in an environment to initiate work tickets, reduce unexpected outages, and share data with Quality Inspectors. This information enables enhanced energy efficiency, audit compliance, and provides the exact locations of faulty or dangerous hotspots in the workplace. One example would be identifying a particular area as a safety “keep-out” zone. Using the generated maps, we can instantly determine if a foreign object is in that zone and notify the user to take action. A more colloquial example would be that in large warehouses, there are specific paths that cranes follow that need to be kept clear. Workers sometimes forget these zones, since the cranes may operate infrequently, and place objects in the zone. Environmental mapping can help identify an unsafe object like a pallet that may be in that path, so the user can move it to avoid a potential collision.
When you record and visualize thermal changes of worksites, you can identify potential maintenance and safety issues by viewing thermal trends, automatically using change detection to identify the presence or absence of objects, and performing historical inspections, audits, and investigations by visualizing site changes over time. For thermal trends, when you have a thermal incident, you can go back and examine, in depth and over time, the thermal characteristics of the object and surrounding environment. This can help you perform a root cause analysis and identify if it was a slowly emerging thermal problem due to poor maintenance activity (e.g. not changing an air filter), or if it was a single incident that caused an immediate thermal spike (e.g. a forklift running into a cooling unit).
Knowing when something is too hot (or too cold) can save equipment and lives. Any one of these points is worthy of their own deep dive, but collectively, they show just how important Thermographer will be to the workplace. And don’t just take our word for it.
