This is called dataset asymmetry: you end up with a huge dataset of valid items and a tiny dataset of faulty items. One solution is to make use of unsupervised learning techniques. These methods allow us to build models without relying on labeled data, that has been specifically identified and labeled as faulty. Instead, they learn from the overall distribution of data points, identifying patterns and deviations. Once we've trained our anomaly detection model, we can deploy it to small devices with limited hardware resources. These lightweight models consume minimal power, and can even operate without an internet connection. -Under the hood, a clustering technique named Gaussian Mixture Models is used.

manufacturing operations rely on effective and accurate inventory and product counting, so that businesses have accurate and known quantities of products to fulfill orders, ship to retailers, and plan their finances accordingly. In typical scenarios, business have up-to-date counts of inputs such as supplies and raw materials, partially completed products that are currently being worked on, and finished goods ready for distribution. To alleviate the burden of counting the units in each stage by hand, which could possibly be very time-consuming, computer vision can be used to identify and quantify parts, supplies, or products instead. +Large scale production and manufacturing operations rely on effective and accurate inventory and product counting, so that businesses have accurate and known quantities of products to fulfill orders, ship to retailers, and plan their finances accordingly.

To alleviate the burden of counting the units in each stage by hand, which could possibly be very time-consuming, computer vision can be used to identify and quantify parts, supplies, or products instead. -There are two distinct counting operations to consider. The first is a "total quantity" at any given time, such as "there are 8 objects on the assembly line at this exact moment". The second scenario is a value that includes a time factor, for example, "14 items moved from point A to point B along the conveyor belt since we began work this morning." Each of these counts are important, so we'll cover both of them here. First, we'll perform a count of items detected in a camera frame, then we will explore how to count the total number of objects that moved past a stationary camera placed above a conveyor belt. +There are two distinct counting operations to consider.

The second scenario is a value that includes a time factor, for example, "14 items moved from point A to point B along the conveyor belt since we began work this morning." Each of these counts are important, so we'll cover both of them here. First, we'll perform a count of items detected in a camera frame, then we will explore how to count the total number of objects that moved past a stationary camera placed above a conveyor belt. A machine learning model that recognizes a distinct item will be needed, along with the camera and hardware. ## Solution -We'll use the [Avnet RZBoard V2L](https://www.avnet.com/wps/portal/us/products/avnet-boards/avnet-board-families/rzboard-v2l/) along with Edge Impulse to accomplish this task. The Avnet RZBoard V2L is a compact single board computer powered by a Renesas RZ/V2L SoC, running a Linux operating system. It has 2gb of RAM, 32gb of onboard eMMC storage, an SD Card slot, micro-HDMI display output, an ethernet port, built-in WiFi and Bluetooth connectivity, USB ports, and a 40-pin GPIO header for expansion.

They mostly use proximity sensors or color sensors to detect objects for counting. Proximity sensors detect the presence or absence of an object based on its proximity to the sensor, while color sensors can distinguish objects based on their color or other visual characteristics. There are some limitations of these systems though; they typically have difficulty detecting small objects in large quantities, especially when they are not in a row or orderly manner. This can be compounded by a relatively fast conveyor belt. These conditions make the object counting inaccurate. +The object counting systems in the manufacturing industry are essential to inventory management and supply chains.

This can be compounded by a relatively fast conveyor belt. These conditions make the object counting inaccurate. ## Our Solution After experimenting with computer vision on the Jetson Nano [in a previous project](https://docs.edgeimpulse.com/experts/featured-machine-learning-projects/quality-control-jetson-nano), I believe that a computer vision system with its object detection capabilities can explore its potential to accurately count small objects in large quantities and on fast-moving conveyor belts. Basically, we'll explore the capability of [Edge Impulse's FOMO models](https://edge-impulse.gitbook.io/docs/edge-impulse-studio/learning-blocks/object-detection/fomo-object-detection-for-constrained-devices) that have been optimized for the GPU in the Jetson Nano. In this project, the production line / conveyor belt will run quite fast, with lots of small objects in random positions, and the number of objects will be counted live and displayed on a 16x2 LCD display. Speed and accuracy are the goals of the project. -![Schematic diagram](../.gitbook/assets/high-speed-counting-jetson-nano/Photo02.png) +![Schematic diagram](../../.gitbook/assets/high-speed-counting-jetson-nano/Photo02.png) ## How Does It Work? @@ -29,23 +30,23 @@ This project utilizes Edge Impulse's FOMO algorithm, which can quickly detect ob The machine learning model (named `model.eim`) will be deployed using the TensorRT library, configured with GPU optimizations and integrated through the Linux C++ SDK.

By using these plastic toys, we will be able to test and refine our sorting techniques in a safe and controlled environment. ## Hardware Selection -We are using [Arduino Braccio ++](https://www.arduino.cc/education/braccio/) for the robotic manipulation. +We are using [Arduino Braccio ++](https://www.arduino.cc/education/braccio/) for the robotic manipulation. -![braccio_plus](../.gitbook/assets/robotic-arm-sorting-arduino-braccio/braccio_plus.png) +![braccio\_plus](../../.gitbook/assets/robotic-arm-sorting-arduino-braccio/braccio_plus.png) For a depth camera, we will be utilizing the [Luxonis OAK-D](https://docs.luxonis.com/projects/hardware/en/latest/pages/BW1098OAK/), which will be doing object recognition and localization.

In ideal conditions, icicles can form at a rate of [more than 1 cm (0.39 in) per minute](https://en.wikipedia.org/wiki/Icicle). In cold climates, many people are injured and killed each year by these solid projectiles, leading responsible building owners to often close sidewalks in the spring to minimize risk.

And of course, using a high-level programming language like MicroPython simplifies any development considerably. -The MicroPython used for this project is available in this GitHub repository: [https://github.com/ronibandini/openMVClassificationPerformance](https://github.com/ronibandini/openMVClassificationPerformance ) +The MicroPython used for this project is available in this GitHub repository: [https://github.com/ronibandini/openMVClassificationPerformance](https://github.com/ronibandini/openMVClassificationPerformance) ## References [https://docs.openmv.io/](https://docs.openmv.io/) -[https://openmv.io/pages/faq#:~:text=The%20OpenMV%20Cam%20consumes%20about,140%20mA%20when%20processing%20images](https://openmv.io/pages/faq#:~:text=The%20OpenMV%20Cam%20consumes%20about,140%20mA%20when%20processing%20images) +[https://openmv.io/pages/faq#:\~:text=The%20OpenMV%20Cam%20consumes%20about,140%20mA%20when%20processing%20images](https://openmv.io/pages/faq) [https://www.edgeimpulse.com/blog/automated-manufacturing-inspection-with-fomo-ad/](https://www.edgeimpulse.com/blog/automated-manufacturing-inspection-with-fomo-ad/) diff --git a/renesas-ra6m5-getting-started.md b/readme/prototype-and-concept-projects/renesas-ra6m5-getting-started.md similarity index 63% rename from renesas-ra6m5-getting-started.md rename to readme/prototype-and-concept-projects/renesas-ra6m5-getting-started.md index 6e2d7f59..8fb373dd 100644 --- a/renesas-ra6m5-getting-started.md +++ b/readme/prototype-and-concept-projects/renesas-ra6m5-getting-started.md @@ -1,14 +1,14 @@ --- -description: Getting Started with machine learning on the Renesas CK-RA6M5 Cloud Kit and Edge Impulse. +description: >- + Getting Started with machine learning on the Renesas CK-RA6M5 Cloud Kit and + Edge Impulse. --- -# Renesas CK-RA6M5 Cloud Kit - Getting Started with Machine Learning +# Renesas CK-RA6M5 Cloud Kit - Getting Started with Machine Learning -Created By: -Swapnil Verma +Created By: Swapnil Verma -Public Project Link: -[https://studio.edgeimpulse.com/public/233106/latest](https://studio.edgeimpulse.com/public/233106/latest) +Public Project Link: [https://studio.edgeimpulse.com/public/233106/latest](https://studio.edgeimpulse.com/public/233106/latest) ## Introduction @@ -20,40 +20,40 @@ This is a Getting Started Guide for the Renesas CK-RA6M5 board with Edge Impulse The Cloud Kit comes with the following items in the box: -- The CK-RA6M5 development board -- RYZ014A PMOD (CAT-M1 Cellular Module) -- SIM card -- Antenna -- 2 Micro USB to A cables -- Micro USB A/B to A adapter cable -- Documentation +* The CK-RA6M5 development board +* RYZ014A PMOD (CAT-M1 Cellular Module) +* SIM card +* Antenna +* 2 Micro USB to A cables +* Micro USB A/B to A adapter cable +* Documentation -![Renesas CK-RA6M5 Cloud Kit](.gitbook/assets/renesas-ra6m5-getting-started/ra6m5-kit.jpg) +![Renesas CK-RA6M5 Cloud Kit](../../.gitbook/assets/renesas-ra6m5-getting-started/ra6m5-kit.jpg) ## Quick Start Project Each CK-RA6M5 board comes preinstalled with a quick-start project.
