AI Technical Summary
Technical Problem
Existing ranging technologies have high hardware costs for monitoring external damage to power lines, and laser point cloud scanning and dual visible light camera equipment are expensive.
Method used
By acquiring images from overhead line tower monitoring devices, the pixel coordinates and single-pixel accuracy of the highest point of the obstacle are determined. The shortest distance from the obstacle to the line is calculated by combining perspective principles, thus avoiding the use of complex laser point cloud scanning or dual visible light cameras.
Benefits of technology
It reduces the cost of ranging hardware, enables the rapid and accurate determination of the distance between obstacles and power lines, and improves the efficiency of power line safety monitoring.

Abstract
本申请涉及一种距离确定方法、装置、设备、存储介质和程序产品。所述方法包括：获取设置在架空线路的杆塔上的监控装置沿平视方向采集的第一图像，第一图像包括障碍物；在第一图像中确定目标点，目标点与第一图像中障碍物的最高点位于同一平面，且目标点在第一图像的竖直中心线上；根据障碍物的最高点相对于目标点的像素坐标和单像素精度，确定障碍物的最高点在实际场景中相对于监控装置所在位置的第一空间位置坐标；根据第一空间位置坐标和各第二空间位置坐标确定障碍物到架空线路的最短距离，第二空间位置坐标为架空线路上各点在实际场景中相对于监控装置所在位置的空间位置坐标。采用本方法能够降低测距成本。
