Abstract: A 3D projection method and a 3D projection device are provided. The method includes: obtaining a first eye image and a second eye image, and forming a fusion image accordingly, wherein the fusion image includes multiple pixel groups, and each pixel group includes a first pixel, a second pixel, a third pixel and a fourth pixel; respectively generating a first projection image, a second projection image, a third projection image, and a fourth projection image based on the first, second, third, and fourth pixel of the pixel groups; and sequentially projecting the first, second, third and fourth projection images. The first and third projection images correspond to the first eye image, the second and fourth projection images correspond to the second eye image, and the first and second eye images are respectively one and another of the left and right eye image.
