AI for Occupancy Analytics | Building a Smart Parking System

Описание: In this video, João Marcos, Product Engineer at Roboflow, demonstrates how to build a computer vision application to manage logistics in an intermodal yard. You will learn how to process drone footage to identify which parking stalls are empty and which are occupied by trailers.

João walks through the entire process, starting with Roboflow Rapid to detect trailers and stall numbers without labeling any data. He then dives into Roboflow Workflows to architect a logic solution for determining occupancy. Finally, he integrates an OCR model (OpenAI) to read the specific stall numbers for actionable reporting.

= Topics covered in this video =
⚡ Rapid Prototyping: How use text prompts to detect objects without labeling and training a model from scratch.
↔️ Workflow Logic: Using "horizontal padding" to verify if a trailer is parked next to a stall number.
⚖️ Advanced Filtering: Using Detection Consensus to identify empty stalls by comparing datasets.
🔡 OCR Integration: cropping, rotating, and sending images to an OCR model to read text.
