The invention discloses a production technology and method for three-dimensional films. The key point of the shooting and production method is that an axis spacing is required during shooting while an image spacing is required during post synthesis; dual sight point dislocation that occurs when human eyes look at an actual object is simulated by using an axis spacing formula and sight focusing of human eyes is simulated by using an image spacing formula; specific data of the axis spacing is related to parameters such as digital camera specifications, the average human pupil distance, lens parameters, specified focal plane distance, projection sizes and the like; and then the camera is translated for a distance of the axis spacing value and two dual sight point images are taken. For post synthesis, images on the left side of the left sight point image and images on the right side of the right sight point image are cut off by using software. A value is pixel number of the image spacing. Then left and right or upper and lower three-dimensional video files are synthesized, and then three-dimensional images are projected by using three-dimensional projection equipment. After a viewer wearing matched three-dimensional glasses, the left eye only sees left images while the right eye only sees right images, so that a three-dimensional watching effect is achieved.
