Claim 12:
13. A depth data measuring method, including:
projecting strip-coded structured light in a scanning manner to the capture area;
using a first image sensor and a second image sensor having a predetermined relative positional relationship to photograph the capture area respectively, in order to obtain the first and second two-dimensional image frames illuminated by the structured light, wherein synchronously turning on the pixel columns in the strip direction corresponding to the current scanning position in the first and second image sensors for imaging, based on the scanning position of the structured light strip;
using a plurality of structured light image frame storage units included in each pixel in each image sensor or N pixel storage sub-columns included in each pixel column or each group of pixel columns to respectively capture strip-coded structured lights of different patterns projected in sequence in the first and the second image sensors to generate a set of image frames each for a different pattern; and
performing pixel matching in the first and the second image sensors on the set of image frames of different patterns for one depth data calculation, to obtain the depth data of the object to be measured in the capture area.
