摘要
针对电力系统巡检过程中双目测距算法的复杂性,提出了一种基于相机高度和俯仰角的单目测距模型,有效解决了电力系统中的测距问题。同时针对测距应用中相机高度和俯仰角的变化,考虑了影响因素对测距精度的影响,具有良好的可靠性。通过测量相机高度和俯仰角,识别图像中目标物体所在区域,根据相机内参对采集到的图像进行坐标变换,获得目标物体的三维坐标信息,根据测距模型计算出实际距离,通过实验验证了所提方法的正确性和有效性。
This paper proposes a monocular ranging model based on camera height and pitch angle, which effectively solves the ranging problem in power systems due to the complexity of binocular ranging algorithms.The model also takes into account the influence of the camera height and pitch angle on the range accuracy, and owns good reliability. By measuring the camera height and pitch angle, the area where the target object is located in the image is identified, and the coordinates of the acquired image are transformed according to the camera internal reference to obtain the 3D coordinate information of the target object, and the actual distance is calculated according to the ranging model. The correctness and effectiveness of the proposed method are verified through experiments.
