Virtual Reality Projection Alignment for Automatic Measuring Truck’s Box Volume in Single Image

Abstract

A virtual reality projection alignment-based volume measurement using single image is presented to reduce the cost of truck’s box volume measuring system. This paper uses the ASM algorithm to establish a virtual reality environment with the parameters of the camera. Then, the tank volume of the truck is determined in the virtual reality environment with by using the EPnP algorithm and the geometric correction calculation. Experiment results show that with the proposed method single image is involved to measure the volume of the truck’s box automatically, complexity of the measuring system is low which leads to good real-time performance, and the measurement error is within 5%.
