Abstract In order to realize the whole process intelligent management of power transmission and transformation engineering, and ensure the safety of tower hoisting and the use effect after hoisting, a moving point coordinate calculation method based on multi-scale Retinex algorithm was proposed. The multi-scale Retinex algorithm was used to enhance the image quality of tower hoisting, the features were extracted by the least square method, and the categories of tower were identified by feature matching. The moving point coordinate calculation models of different categories of tower hoisting were established by Picard method, and the moving point coordinates of multi-lifting point constraint rope of tower hoisting were calculated. The test results show that this method has good image enhancement effect. The test results of BIQI index and BRISQUE index are more than 4.6. It can complete the distinction of towers in the image, obtain the classification results of towers, calculate the moving point coordinates of lifting point restraint rope system, and ensure the safe lifting of towers. The inclination angle is less than 10 °, and the more uniform the section bending moment is more than 92.5%.
