1. A system for measuring a naked-eye stereoscopic image, comprising an image acquisition device, a naked-eye stereoscopic display device and a processor, the processor being connected with the image acquisition device and the naked-eye stereoscopic display device, respectively;
the naked-eye stereoscopic display device is configured to display preset images in sequence, wherein each of the preset images is a monochromatic sub-view in a view from each of m view points, or a part of a monochromatic sub-view in a view from each of the m view points;
the image acquisition device is configured to acquire monochromatic images by capturing display contents of the naked-eye stereoscopic display device, and send the monochromatic images to the processor; and
the processor is configured to acquire at least one preset crosstalk amount to each stereoscopic pixel of the naked-eye stereoscopic display device from each of the m view points according to the monochromatic images, wherein each of the at least one preset crosstalk amount represents a proportion coefficient that measures how much a view from another view point affects a color value of a view from a target view point;
wherein when acquiring the at least one preset crosstalk amount to each stereoscopic pixel of the naked-eye stereoscopic display device from each of the m view points according to the monochromatic images, the processor is configured to:
for each stereoscopic pixel in the monochromatic images from each of the m view points,
acquire pixel values of the stereoscopic pixel;
acquire a color value of the stereoscopic pixel according to the pixel values;
acquire a total monochromatic crosstalk amount to the stereoscopic pixel according to color values of the stereoscopic pixel from each of the m view points, so as to acquire the at least one preset crosstalk amount.
