Disclosed are an image acquisition method, apparatus and device based on multiple cameras. The image acquisition method based on multiple cameras comprises: acquiring a first image photographed by a first camera and a second image photographed by a second camera simultaneously with the first camera (S1); obtaining an overlapping region of the first image and the second image via geometrical optics (S2); removing the overlapping region from the first image to obtain a standby image after removal of the overlapping region (S3); and splicing the standby image and the second image (S4). Therefore, the technical effects of saving on calculation power and accelerating the splicing speed are achieved.
