A coupled localization method for shot photoelectric sensors based on an improved bat optimization algorithm

To realize comprehensive, accurate, and real-time positioning of target objects, and to overcome the problems of insufficient positioning accuracy and susceptibility to interference that a single sensor may face in complex environments, we propose a coupled positioning method for radio photoelectric sensors based on an improved bat optimization algorithm. After extracting the laser point cloud plane of the radio photoelectric sensor, a high-precision control field is established based on it. Based on the control points in the high-precision control field of the shooting photoelectric sensor, an equation for the plane parameters of the shooting photoelectric sensor is established. The optimization objective function of the shooting photoelectric sensor plane equation is established according to the unknown parameters of the plane equation and rotation matrix. Then, the bat optimization algorithm, which is improved by introducing a second-order oscillation link, is used to optimize and solve the optimization objective function of the shooting photoelectric sensor plane equation. The calibration results of the shooting photoelectric sensor plane parameters are obtained. The power function is used to couple and fit the calibration results of the multiple plane parameters of the shooting photoelectric sensor, and the coupling positioning result of the shooting laser sensor is obtained. The positioning accuracy is improved through multi-sensor collaboration. Experiments show that this method can effectively extract the laser point cloud plane of a radio photoelectric sensor, realize its laser plane parameter calibration, and accurately locate the target in space with a strong application effect.
