The invention belongs to the technical field of intelligent traffic control, and provides a traffic intersection panoramic video acquisition device and method based on frame image contour splicing, and the method comprises the steps: S1, erecting an image collection device, and calculating an image overlapping region; s2, gray processing is carried out on the image, and dynamic foreground removal processing is carried out on the gray image; s3, selecting and correcting a difference threshold value; s4, carrying out feature unit division on a gray level image overlapping region of which the dynamic foreground is removed; s5, calculating a characteristic index G, and determining a target unit; s6, performing one-to-one mapping on the target units in the overlapping areas of the two adjacent images, completing splicing of the two adjacent images, and finally splicing to form a panoramic image; and S7, carrying out inverse transformation on the spliced final image to restore a color image, and transmitting the panoramic image to a background at a speed of P frames per second to form a continuous video image. The image splicing is completed under the condition that image distortion is not processed, a large amount of computation is reduced, and the equipment investment cost is reduced.
