Panoramic image generation method and system and engineering vehicle

The invention discloses a panoramic image generation method and system and an engineering vehicle, and relates to the technical field of panoramic image generation. The method comprises the following steps: acquiring an imaging picture of each camera, and determining an imaging area of an extension part on the imaging picture; based on the pose relation between the camera and the vehicle body of the vehicle, determining the corresponding relation between each position point around the vehicle body and the imaging picture; on the basis of the corresponding relation, setting the weight of the position points corresponding to the interior of the imaging area mapped to the panoramic image to be 0, and determining a target weight value of each position point mapped to the panoramic image in combination with the initial weights of other position points corresponding to the exterior of the imaging area; determining a target pixel value of each pixel point on the panoramic image based on the pixel value corresponding
