Embodiment Construction

[0055] Below in conjunction with accompanying drawing, the present invention will be further described:

[0056] Such as Figure 7 As shown, a long-distance non-contact luggage volume detection system includes:

[0057] The luggage object image acquisition and processing module extracts the outline of the luggage object and the depth information of each part from the background image, and generates a depth map;

[0058] The three-dimensional space size reconstruction module of luggage objects can accurately construct the three-dimensional space model of luggage objects;

[0059] The volume calculation module is used to judge the type of the three-dimensional space model of the luggage object, and calculate the volume of the luggage object according to the judgment result; this module can accurately calculate the volume of both rigid and flexible luggage objects;

[0060] The luggage placement prompt module displays the effective luggage detection and placement area and angle...

Abstract

The invention relates to a long-distance non-contact luggage volume detection system and a method thereof. The system and the method are used to perform long-distance non-contact hard and soft luggage volume detection in airports, train stations or other scenes. The system comprises a luggage object image acquiring and processing module, a luggage object 3D spatial dimension reconstruction module, a volume calculation module, a luggage placing position prompt module, a feedback module, a camera, and a central processor. The technical problems to be solved in the invention include: automatically identifying a luggage in a detection area under a long-distance space environment; processing the surface geometric characteristics of the luggage after claiming; building a 3D space model; judging whether the luggage is soft or hard; calculating the volume using different algorithms; and feeding the volume detection result and suggestion back to a user through a multi-channel interaction technology. The invention provides a convenient and quick luggage volume self-detection method for passengers, and inconvenience brought by an oversized luggage is avoided.

Description

technical field [0001] The invention relates to a long-distance and non-contact luggage volume detection system and method for scenarios such as airports and stations. Background technique [0002] Airports, stations and other places have strict regulations on the size of carry-on luggage. However, most of the current luggage volume detection systems are simple iron frames. Specific and accurate baggage size and handling recommendations. Depth detection technology can detect the distance and surface geometric changes of objects in three-dimensional space, but there are still problems such as low accuracy and cumbersome correction for measurement calculations. 3D real-sensing detection technology can provide easier correction methods and higher accuracy in object measurement. The non-contact book scanning device with the announcement number CN105095894A uses the cooperation of the depth information collection component, the color information collection component, and the se...
