To reduce the time and economic costs of freight cableway path planning, according to factors such as geographical information, project requirements, and costs of cableway erection and operation, the requirements of cableway path planning are proposed, and the technical process of automatic path planning is developed. To meet the requirements of cableway erection, an automatic method for screening loading and unloading points based on clustering was presented to achieve the avoidance of cableway to highway, and by the use of three-dimensional terrain data, a search method for trestle positions based on terrain adaptation is proposed. The selected trestle positions can ensure that the distance between the bearing cable of the cableway and the ground meets the construction requirements, and in this way the number of trestles is optimized to reduce the cost of the cableway. The field applications of the proposed method demonstrate that it can provide thousands of cableway paths and trestle positions automatically in around half an hour, showing fast planning and comprehensive data analysis.
