Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings.

[0018] Such as Figure 1-3 As shown, the obstacle recognition and ranging system for the roller construction process includes two 16-line laser radars, four industrial cameras and an embedded industrial computer connected to the roller construction instructions. An industrial computer 2 is installed in the cockpit of the road roller 1, and an industrial camera 3 for obtaining image information of the construction area of ​​the road roller is installed around the top of the cockpit of the road roller. The camera and the laser radar are respectively connected to the industrial computer through the expansion network port of the industrial computer, and the inter-node communication is established between the camera and the laser radar through the Robot Operating System (ROS) system.

[0019] Using the distance measurement method of this system, firstly, the image data of ...

Abstract

The invention discloses an obstacle identification distance measuring system and a method oriented to the construction process of a road roller, The system comprises an embedded industrial control computer, an industrial camera is arranged around the top of the cockpit of the road roller, a lidar is respectively arranged on the front side and the rear side of the road roller, the industrial cameraand the lidar are connected with the industrial control computer, and communication between the industrial camera and the lidar is established through a ROS system. The system fuses the image and point cloud data to realize the obstacle recognition and measurement in the construction process of road roller. The system has the characteristics of full coverage of construction environment, high accuracy of target recognition, high accuracy of obstacle position measurement, good real-time performance and strong anti-interference ability, and is suitable for unmanned road roller construction.

Description

technical field [0001] The invention relates to an obstacle identification and distance measurement system and method, in particular to an obstacle identification and distance measurement system and method for the construction process of a road roller. Background technique [0002] Machine vision is to use visual sensors to obtain pictures and use image processing systems to perform various measurements and judgments. It is an important branch of computer science. , pattern recognition, artificial intelligence, signal processing, optomechanical integration and other fields. [0003] In the research of automatic driving system, target detection and ranging is an important part of automatic driving system, which directly affects the safety and reliability of the whole system, so it puts forward higher requirements for its real-time performance and accuracy. Compared with the automatic driving system of the car, the construction environment elements of the road roller are rela...
