AI Technical Summary

Technical Problem

Existing weighbridge systems for measuring vehicle weight are cumbersome and costly, and there is a need for a non-contact method to accurately measure vehicle weight, especially for cargo transported by trailers and trucks, to comply with environmental regulations and prevent road damage.

Method used

A camera-based system that captures vehicle motion over a speed bump, analyzes the image using AI to calculate weight through deep learning, utilizing a vehicle recognition unit, motion analysis unit, and AI calculation unit to determine vehicle characteristics and weight.

Benefits of technology

Enables accurate, real-time, and non-contact measurement of vehicle weight, reducing the need for costly infrastructure and providing compliance with environmental regulations.

Abstract

The present invention relates to a camera image-based moving vehicle weight measurement apparatus capable of non-contact measurement of the weight of a moving vehicle passing over a road speed bump, the apparatus comprising, as main components: a vehicle recognition unit including a server and a camera that captures movement of a vehicle; a vehicle motion recording unit for capturing movement of the vehicle when the vehicle passes over the road speed bump; a vehicle motion analysis unit which uses the captured image of the vehicle so as to quantitatively analyze motion of the vehicle and convert same into data, thereby extracting a time-series vehicle motion displacement amount, and which extracts core data from the motion displacement amount; and an artificial intelligence calculation unit for calculating, on the basis of the core data of the vehicle motion analysis unit, the weight of the vehicle by means of deep learning artificial intelligence.
