The invention relates to the technical field of automobiles, in particular to a static calibration method and device for a vehicle-mounted camera, a vehicle and a storage medium, and the method comprises the steps: 1, calibrating the camera based on a Zhang's calibration method, and obtaining an internal parameter initial value and an external parameter initial value corresponding to the camera; step 2, calculating distortion parameters of the camera; 3, optimizing the internal parameter initial value and the external parameter initial value based on an adaptive large neighborhood search algorithm to obtain a target internal parameter and a target external parameter; and step 4, calibrating the camera according to the optimized internal parameters, the optimized external parameters and the distortion parameters. According to the method, on the basis of the Zhang's calibration method, the initial solution of the camera is iteratively optimized in combination with the adaptive large neighborhood search algorith
