How to manage feature flags in ASP.NET Core apps with Azure?
No matter how simple or complex an application is, choosing the right configuration provider right at the start will mak...
In my previous article, I wrote about the Azure Digital Twins service that enables the visualization of physical environments and associated devices. This time I would like to present another interesting scenario, in which IoT devices and Azure cloud services play a crucial part too, thanks to Custom Vision solution.
I talked about data generated by IoT devices, like temperature or humidity, but there are even more exciting scenarios. Imagine that there is an IoT device with a camera that can analyze the crowd (to see how many people are in the room or what emotions they are showing) or analyze packages on the production lines to detect damages.
If you did not hear about Azure Cognitive Services, let me introduce this topic and explain how these tools support the Internet of Things solutions.
Azure Cognitive Services are services and tools available in Azure cloud that allow developers to build intelligent applications without having direct AI or data science skills and knowledge. The main purpose of Azure Cognitive Services is to help developers create applications that can see, hear, speak, and understand.
The Azure Cognitive Services catalog consists of five main pillars:
As said above, the cloud-based Custom Vision service gives developers access to advanced algorithms for image processing and returning information. In a simple scenario, after uploading an image or providing an image URL, Microsoft Custom Vision algorithms can analyze visual content in different ways based on inputs and user choices and then return appropriate results. Below you can see an example of face analysis.
Another interesting scenario where Custom Vision service can be used is related to production lines and packages. For instance, this solution can consist of an IoT device with a connected camera to detect potentially damaged boxes.
Internet of Things device market is growing fast right now. There are many manufacturers that provide IoT devices not only with integrated sensors (e.g. temperature sensor) but there are also devices like GPS trackers or devices with camera to constantly monitor the selected area. During the recent Microsoft conference called Build, there were many interesting announcements, including IoT devices for monitoring purposes. Below I present an example of IoT product from Lenovo which will be available in the Azure IoT Device Catalog this summer. This solution enables running Custom Vision module on IoT devices with camera.
Another great product released by Microsoft is the Azure Kinect camera. It enables real-time video analysis and works with Custom Vision service. I encourage you to watch this short video below.
The main question is: How can we use Custom Vision service together with IoT devices? Let’s go over some examples.
Safety on the construction site is the most important aspect. Each worker should wear a helmet together with a jacket. Without the protective equipment, workers are not allowed to be on the construction. To avoid danger, it’s possible to implement IoT devices with a camera to analyze if workers wear helmets and jackets. If there is someone without the protective clothing, an alert can be sent, based on the Custom Vision analysis results.
Another useful example of using IoT devices together with Custom Vision service is to monitor packages on the production lines. It would be much more complicated to manually check each package to see if there are any damages. In this case, IoT device with a camera could be used to analyze packages on the production line and alert if some of these packages are damaged or not properly closed.
Crowd analysis can also be a good example of a case where Custom Vision service and IoT devices play a significant role. As an organizer of some event, you may need to measure how many attendees were in a specific area or check if there were more women or men. Of course, there are many other parameters you could collect and analyze.
As you can see, the Internet of Things solutions are not limited to sensors and collecting data from them. There are a lot of cases of how IoT devices together with Azure Cognitive Services can boost productivity, solve some monitoring problems and provide valuable information.
Now you know that Azure Cognitive Services consists of five main pillars: Vision, Speech, Language, Web Search and Decision and are aware of the possibilities of each solution.
This specific area of IoT is still growing so I expect to see more exciting scenarios in the future. In the meantime, feel free to get in touch for more information!
