Raspberry Pi Potato Sizing System

@AwaisChaudhry

Hello, I will design and implement a Raspberry Pi potato sizing system with a camera, running reliable image processing to measure potato sizes on a continuous conveyor. My approach is to start with a robust hardware setup using a Raspberry Pi Zero 2 W or 4, a Pi Camera Module or USB/IP camera depending on your preference, and a compact lighting plan to ensure consistent measurements. I will develop a Python/OpenCV pipeline that detects potatoes on the belt, measures relevant dimensions, and outputs a concise size summary for display. The system will be tested for accuracy by calibrating against known reference objects and tuned for steady throughput. I will also set up a suitable display interface (on-screen display, HDMI monitor, or a small touchscreen) and provide a simple, maintainable codebase with clear instructions for future adjustments. This project will cover camera integration, image processing, and a stable display setup, keeping the workflow fast and reliable for continuous operation. Which display type do you prefer for showing the potato size summary (screen type and resolution)? What display type and resolution do you prefer for showing the potato size summary on screen?

I recommend a Raspberry Pi 4 + HQ/USB camera with controlled lighting and OpenCV-based image processing for accurate size detection on a moving conveyor. For display, a 7” HDMI touchscreen is ideal—reliable, easy to integrate, and allows real-time stats (count, size distribution, alerts).

Hello, I understand you need a Raspberry Pi system to measure and summarize potato sizes on a continuously moving conveyor. I propose using a Pi Camera Module integrated with OpenCV for real-time image capture and processing. The system will detect individual potatoes, calculate size metrics, and display a running summary on a compact touchscreen or HDMI monitor, depending on your preference and mounting constraints. The software will handle calibration, lighting variations, and conveyor speed adjustments to ensure reliable, accurate measurements. Deliverables will include fully commented Python code, wiring schematic for the camera and display, installation notes, and a guide for calibrating and operating the system. Questions: 1. Do you prefer a dedicated touchscreen on the Pi or an external HDMI/monitor display for the summary? 2. Should the system also log size data for later analysis, or only provide real-time display? Thanks, Asif

Greetings, I have read the project description but haven't found any details requirements open a chat to discuss requirements in details.

@maxscender

I can help you. To ensure accuracy on a continuous belt, we must solve for motion blur and potato clustering. I will implement a high-shutter-speed capture pipeline using OpenCV, paired with a Watershed transformation to accurately segment potatoes that are touching or overlapping. A hidden challenge in this environment is "calibration drift" and vibration. I will use a fixed-plane calibration matrix to convert pixels to millimeters, ensuring measurements remain precise regardless of belt speed. For the display, a local web-based dashboard hosted by the Pi is more practical than a physical monitor. This allows any tablet or phone on the floor to view real-time stats via Wi-Fi, keeping the core electronics in a dust-proof enclosure away from the conveyor's vibration. I will also include a color-space filter to prevent the system from miscounting soil or debris as small potatoes.

Hi, I recently developed a Raspberry Pi vision system for object measurement on a moving conveyor, where the main challenge was achieving consistent size detection under varying lighting and motion conditions. From your description, you need a Pi-based camera system to measure and summarize potato sizes in continuous flow. The key considerations will be stable image acquisition, proper lighting control, accurate contour detection, and real-time processing without frame drops. My approach would be: 1. Select camera (Pi HQ or global shutter USB for motion accuracy) 2. Implement image processing (OpenCV: segmentation + contour sizing) 3. Calibrate pixel-to-mm conversion using reference object 4. Optimize processing pipeline for real-time performance 5. Display summary via HDMI touchscreen or web dashboard Quick question: What is the conveyor speed and expected size range of the potatoes? Best regards Mykola

Hi, I have strong experience with Raspberry Pi computer vision systems using OpenCV and Python, and I can build a robust, real-time potato sizing system for your conveyor belt application. Camera Setup: I recommend using a Raspberry Pi Camera Module (v2 or HQ) mounted above the conveyor belt for consistent imaging. A USB camera or IP camera can also be integrated if preferred. An LED ring light can be added for reliable results in varying lighting. Sizing Algorithm: Using OpenCV, the system will detect each potato as it passes, measure its pixel dimensions, and convert to real-world measurements using a calibrated pixels-per-mm ratio. Contour detection and perspective correction ensure reliable results with continuous flow. Display: I recommend a 7-inch HDMI touchscreen showing a live camera feed with bounding boxes on each detected potato, plus a real-time summary panel with size categories (small/medium/large), counts, and average dimensions. Data can also be logged to CSV for later analysis. Deliverables: Fully documented Python source code, setup instructions, calibration guide, and a live demo video of the system in operation. I can start immediately. Happy to discuss your conveyor dimensions and lighting conditions to tailor the solution. Looking forward to working with you!

I have successfully deployed several computer vision solutions on Raspberry Pi hardware for industrial sorting and real-time object sizing, which aligns perfectly with your potato measurement system. My background includes optimizing OpenCV pipelines to handle high-speed conveyor belts while maintaining high precision in dimension estimation and volume calculation. By leveraging the Raspberry Pi’s ISP and hardware acceleration, I can ensure that your system provides accurate, real-time feedback and data logging without the latency bottlenecks typical of standard implementations, drawing on my experience developing automated quality control systems for similar agricultural environments. To deliver a robust solution, I will implement a custom OpenCV workflow that utilizes a calibrated camera matrix to correct for perspective distortion and accurately map pixel measurements to metric units. I plan to use adaptive thresholding and contour analysis—or a lightweight, Pi-optimized model if the environment is complex—to isolate potatoes and measure their major and minor axes in real-time. The system will aggregate this data into a structured format, such as a CSV log or a local SQL database, providing you with automated summaries of size distributions and grading metrics that can be accessed via a local dashboard or exported for further analysis. Could you clarify the average throughput speed of the conveyor and the typical height at which the camera will be mounted above the belt? Additionally, are there specific lighting constraints or environmental factors we should consider when selecting the lens? I am available to jump on a brief call or chat to discuss the optimal hardware configuration and ensure we achieve the high-resolution accuracy required for your grading standards; let me know your availability to take this forward.
