1. A texture image acquiring device, comprising: a collimator and an image sensor,
wherein the collimator is stacked on the image sensor, the collimator comprises a lens array and diaphragm component, wherein the diaphragm component is adjacent to the image sensor,
the diaphragm component includes a first diaphragm layer and a second diaphragm layer;
the lens array is configured to allow light rays to be converged and incident on the first diaphragm layer,
the first diaphragm layer is configured to allow light rays incident on the first diaphragm layer to pass through and be incident on the second diaphragm layer, and to restrict an angle of light rays capable of passing through the first diaphragm layer,
the second diaphragm layer is configured to allow light rays incident on the second diaphragm layer to pass through, and to restrict an angle of light rays capable of passing through the second diaphragm layer,
the image sensor is configured to sense light rays incident on the image sensor for acquiring a texture image,
the lens array comprises a plurality of lens units arranged in an array,
the first diaphragm layer comprises a plurality of first through holes arranged in an array,
the plurality of lens units and the plurality of first through holes overlap in a one-to-one correspondence in a direction perpendicular to the first diaphragm layer, and
at least one first through hole of the first through holes has a first opening center, and the first opening center is located at a focal point of a lens unit corresponding to the first through hole.
