Research on Camera Calibration Methods in Substation Visual Inspection Technology
Machine vision-based substation inspection can reconstruct the structure of substations,detect the safe distance between workers and high-voltage equipment,enhance the reliability of inspection work,and ensure per-sonnel safety.Substation inspection work needs to consider factors such as safe distances,the range of camera-collected information,and the distance between the camera and inspection equipment.Firstly,based on Zhang Zhengyou's calibration method,the relationship between the coordinates captured in images and the world coordi-nates is analyzed.Then,considering parameters such as camera accuracy and depth of field,a coordinate transfor-mation matrix is obtained using Zhang Zhengyou's calibration method to determine the optimal distance between the camera and inspection equipment.Finally,a model to validate the algorithm's effectiveness is constructed.
