Abstract

FIELD: transportation.

SUBSTANCE: invention relates to methods and devices monitoring security of cargo during transportation. Sent cargo is tracked by means of security video cameras. Image processing is performed by special software. Image of sent and recieved cargo is obtained by using video cameras, whereupon on the basis of camera readings and with the help of computer analysis of images 3D scenes with sent and recieved cargo are created, geometric characteristics of the cargo are determined and stored. In the presence of differences in geometric characteristics of sent and recieved cargo the conclusion on the cargo integrity violation is made.

EFFECT: technical result is high safety of cargo.

Description

The invention relates to methods and devices for tracking the safety of cargo during transportation. Designed to automatically track cargo integrity violations.

There are ways when the transported cargo is closed in special boxes and sealed. However, this method is not suitable for cargo transported in open wagons, for example, when transporting scrap metal.

As the closest analogue, a method for remote monitoring of the safety of cargo in a train is adopted, given in RU 2138077 C1, 09.20.1999.

The technical result of the method is the automatic fixation of the differences between the sent and received goods. Sent cargo is removed using cameras. Image processing is carried out by special software. The scene obtained as a result of image processing completely captures the geometric characteristics of the consignment and therefore is called an electronic-geometric seal. Upon receipt of the cargo with the help of video cameras, the received cargo is removed before receiving the cargo. After processing the image, the resulting scene is compared with the scene taken during the shipment. If the integrity of the cargo was violated along the way, then when comparing the scenes, differences will be found.

A method for verifying the safety of cargo during transportation, including obtaining an image of the cargo and comparing its geometrical characteristics, characterized in that they receive an image of the sent and received cargo using cameras, is based on the testimony of the cameras using computer image analysis to build 3D scenes with the sent and received load, determine and remember the geometric characteristics of the cargo and if there are differences in the geometric characteristics of the sent and received Ruza conclude violation of the integrity of the cargo.

As camcorders, TOF cameras can be used.

The essence of the invention lies in the fact that the loading and unloading fronts are equipped with video cameras. Including TOF cameras [Time-of-flight camera http://en.wikipedia.org/wiki/Time-of-flight_camera; Kinect http://ru.wikipedia.org/wiki/Kinect], able to receive 3D images with high accuracy immediately at the exit from the camera.

Camcorders are positioned to cover the loading or unloading space. Based on the testimony of the cameras, a 3D scene of the space covered by the cameras is built using computer image analysis. The 3D scene in this case uniquely determines the geometric characteristics of the object and is actually an electronic-geometric seal. Also, the 3D scene is built after the transportation of goods before unloading. Comparison of 3D scenes obtained before and after transportation, allows you to capture the differences and automatically determine the violation of the integrity of the cargo.

To build a 3D scene in real time, KinectFusion software can be used [KinectFusion - construction of a 3D scene in real time http://habrahabr.ru/post/126379/3]. This software selects objects in the image.

After building a 3D scene, comparing the geometry of the objects becomes a simple engineering task and is carried out by sorting the objects of the resulting 3D scenes.

Claims (2)

1. A method of verifying the safety of cargo during transportation, including obtaining an image of the cargo and comparing its geometric characteristics, characterized in that they receive an image of the sent and received cargo using video cameras, while 3D scenes with the sent and received cargo, determine and remember the geometric characteristics of the cargo and if there are differences in the geometric characteristics of the sent and received cargo ie finding of violation of Georgia's territorial integrity. 2. The method according to claim 1, characterized in that TOF cameras are used as video cameras.
