Embodiment

[0044] A system for measuring the minimum package size of an article mainly includes four parts, a RealSense camera, a projector, a measuring platform and a PC computer. Both the RealSense camera and the projector are connected to the PC through the USB interface, and the PC controls the projector through the USB, and receives the image data collected by the RealSense camera through the USB. When the measured object is placed on the measurement platform, the RealSense camera can quickly collect the visual image data and send it to the PC, and use the software algorithm of the PC for further data processing to quickly measure the package size of the measured object.

[0045] Divided by functional modules, the minimum package size measurement system for objects of the present invention is divided into five modules, a projector control module, a data acquisition module, a data processing module, a camera calibration module and a mechanical bearing module. The projector control modu...

Abstract

The invention discloses a size measurement system and method based on a RealSense camera. The measurement system includes a projector, a RealSense camera, a data processing module and a measurement platform; the RealSense camera and the projector are arranged above the measurement platform through a bracket, and the measured object is placed on the On the measurement platform, the calibration pattern projected by the projector on the measurement platform is used to calibrate the pose of the RealSense camera. The RealSense camera collects the image of the measured object on the measurement platform and sends it to the data processing module. The data processing module obtains The smallest package size of the item under test. The invention can quickly measure the minimum package size of articles, adapt to higher-speed flow operation, and has higher measurement accuracy.

Description

technical field [0001] The invention relates to the measurement field using stereo vision, in particular to a dimension measurement system and method based on a RealSense camera. Background technique [0002] In the context of modern consumption, the logistics industry plays an important role, and the efficiency of logistics operations directly affects the efficiency of the entire industrial chain system. In recent years, with the further development of the economy, the rise of Internet e-commerce and the emergence of new consumption models, the logistics volume has shown a trend of rapid growth. The high cost and the surge in logistics volume have put forward new challenges for automated and intelligent logistics management. No small request. [0003] The packaging of goods is often involved in the logistics industry. For various goods of different sizes and shapes, logistics operators usually rely on empiricism to select the specifications of the packaging box, resulting ...
