The invention discloses an excavator front-view camera video stitching method in the technical field of video stitching and audio processing, and the method comprises the steps: obtaining images of an excavator front-view binocular camera, adding a timestamp to each frame of obtained image, and selecting the images with the same timestamp to form a to-be-stitched image pair; distortion correction is carried out on the to-be-spliced image pair through camera calibration, a homography matrix of the image pair after distortion correction is calculated, projection transformation is carried out on the homography matrix, and a same plane image is obtained; stitching stitching and stitching trace elimination are carried out on the overlapping area of the same plane image, stitching is dynamically updated, and a ghosting-free and distortion-free real-time stitching result is obtained; and compressing, coding and packaging the real-time splicing result frame of the excavator terminal in sequence, and rendering and dis
