The invention discloses a jib crane hoisting operation anti-collision method and a system. According to the system, an obstacle classification model is established, and the appearance and position information of obstacles in an operation area is accurately acquired by adopting a crane jib head autonomous detection and study method. A cylindrical coordinate system of a crane is established, the operation area is divided into different sectors according to slewing angles, the sectors are divided into different fan-shaped grids according to the distance from a slewing center, environmental data of the operation area are precisely stored based on the fan-shaped grids, and a hoisting safe operation three-dimensional boundary wall is generated by utilizing the data of the fan-shaped grids. Motion and position parameters of a crane jib at the next moment are predicted by using a weighted linear regression model based on the position information of the crane jib at the most recent 20 moments. Aiming at the predicted motion and different distances from the boundary wall of the crane jib, crane jib control strategies such as no intervention, speed limiting, micro-motion and prohibition are adopted. Functional tests in an actual operation environment show that the system can effectively prevent the collision between the crane jib and the obstacles in the operation area.
