A depth estimation method based on light-field data distribution includes the following steps: S1. adjusting pixel distribution of input light-field images to generate a series of refocused light-field images having different focal lengths; S2. for a spatial point, corresponding to a macro-pixel, extracting intensity ranges for the macro-pixel from the refocused light-field images, and then selecting one refocused light-field image corresponding to a minimum intensity range, the focal length of the selected refocused light-field image being taken as a scene depth of the macro-pixel; the macro-pixel corresponding to one point in an actual scene, the intensity range of the macro-pixel being a variation range of intensity values of all points within the macro-pixel; and repeating the step S2 to obtain scene depths of all macro-pixels.
