【摘要】 本文针对标准金属量器自动检定流程中存在的量器安装定位烦琐、过程缓慢的问题，通过分析标准金属量器的图像特征及其与相机间的相对位姿要求，提出一种基于单目视觉的量器空间定位方法。该方法使用激光测距获取相对距离、YOLOv4识别玻璃液位管和表尺位置，并分割图像、使用标准件法测量罐体轴线旋转角度，对量器与相机间的当前相对位姿进行数值化并提供定位引导。实验证明：该方法测量精度满足需求，能为工作人员提供直观的定位意见。更多还原

【Abstract】 Aiming at the cumbersome and slow installation and positioning of standard metal gauges in the automatic verification process, this paper proposes a spatial positioning method based on monocular vision by analyzing the image features of standard metal gauges and the relative pose requirements between the standard metal gauges and the camera.The method uses laser ranging to obtain relative distance, YOLOv4 to identify the position of the glass liquid level tube and the gauge, and splits the image, uses the standard part method to measure the rotation Angle of the tank axis, numeralizes the current relative pose between the gauge and the camera, and provides positioning guidance.The experimental results show that the measurement accuracy of this method meets the requirement and can provide intuitive positioning advice for the staff.更多还原
