Abstract

The invention discloses an automatic acquisition system of baggage appearance information based on monocular vision and a method thereof. The system mainly comprises a loading platform, a color camera, a lighting device, an image processing module and a server, wherein the loading platform comprises a horizontal calibration board, a vertical calibration board and a mounting platform. The method comprises the following steps: segmenting a baggage area from a baggage image to obtain projection of a baggage on the horizontal calibration board and the vertical calibration board, so as to calculate the length, width and height of the baggage; and transforming color space of the baggage image to extract main color features of the baggage, and categorizing the main color features to obtain information on the color of the baggage. In addition, the method also comprises extraction and categorization of texture features of the baggage to obtain texture information of the baggage. Due to the automatic extraction of information on the size, color and texture of the baggage through computer vision and image processing, the invention can realize the automatic acquisition of the baggage appearance information, and is particularly suitable for acquisition of baggage information in accidents in small airports, railway stations, bus stops and the like.

Description

technical field [0001] The invention belongs to the technical field of computer vision and image processing, and in particular relates to a system and method for automatically acquiring luggage appearance information based on monocular vision. Background of the invention [0002] With the rapid development of the air passenger transport market in various countries in the world, the number of passengers flying to and from various places is constantly increasing. However, affected by various uncertain factors such as airports, baggage handling, sorting equipment, personnel quality, and even weather, there are more and more accidents of abnormal transportation of flight baggage. [0003] In order to effectively deal with abnormally transported luggage, the world luggage inquiry system WORLDTRACER came into being. This system is a modern information management system that can realize automatic check and search of accident baggage, real-time monitoring and system management. It...
