摘要:本发明公开了一种带压堵漏机器人自主漏点定位方法,通过摄像组件采集管道处的RGB图像和深度图像;将RGB图像和深度图像背景噪声滤除,得到去噪后的背景;通过训练好的YOLO v4模型对管道漏点进行识别,通过识别得到的管道漏点位置信息结合图像信息来粗略定位管道漏点的粗略三维位置;机器人上的机械臂基于上述的粗略三维位置,将携带有压力传感器的探针末端移动至漏点位置附近;通过对压力传感器所收集的压力数据,获知探针末端与管道的接触状态;通过循环修正对管道漏点的定位位置,指引机械臂将探针执行末端不断接近管道漏点,获得准确的管道漏点三维坐标位置。通过结合图像识别定位信息与压力信息来实现对复杂场景自动化管道漏点的精确定位。

Abstract: The invention discloses an autonomous leakage point positioning method of an under-pressure leaking stoppage robot. The autonomous leakage point positioning method comprises the following steps that an RGB image and a depth image at a pipeline are acquired through a camera assembly; background noise of the RGB image and the depth image is filtered to obtain a denoised background; a pipeline leakage point is identified through a trained YOLO v4 model, and the rough three-dimensional position of the pipeline leakage point is roughly positioned through the pipeline leakage point position information obtained through identification in combination with the image information; a mechanical arm on the robot moves the tail end of a probe carrying a pressure sensor to the position near the leakage point based on the rough three-dimensional position; the contact state of the tail end of the probe and the pipeline is obtained through pressure data collected by the pressure sensor; and by circularly correcting the positioning position of the pipeline leakage point, the mechanical arm is guided to enable the execution tail end of the probe to continuously approach the pipeline leakage point, and the accurate three-dimensional coordinate position of the pipeline leakage point is obtained. The accurate positioning of the leakage point of an automatic pipeline in the complex scene is realized by combining the image recognition positioning information and the pressure information.
