1. A method for depth mapping, comprising:
- receiving in a digital processor an image of a pattern of spots that has been projected onto a scene, which includes a feature having a set of elongate appendages, which have respective transverse dimensions that are less than twice an average distance between the spots in the pattern that is projected onto the feature;
processing the image in order to segment and find a three-dimensional (3D) location of the feature; and
connecting the spots appearing on the feature in the 3D location in order to extract separate, respective contours of each of the elongate appendages in the set.

Abstract
A method for depth mapping includes receiving an image of a pattern of spots that has been projected onto a scene, which includes a feature having a set of elongate appendages, which have respective transverse dimensions that are less than twice an average distance between the spots in the pattern that is projected onto the feature. The image is processed in order to segment and find a three-dimensional (3D) location of the feature. The spots appearing on the feature in the 3D location are connected in order to extract separate, respective contours of the appendages.

12. Apparatus for depth mapping, comprising:
-
an imaging assembly, which comprises a sensor that is configured to capture an image of a pattern of spots that has been projected onto a scene, which includes a feature having a set of elongate appendages, which have respective transverse dimensions that are less than twice an average distance between the spots in the pattern that is projected onto the feature; and a processor, which is configured to process the image in order to segment and find a three-dimensional (3D) location of the feature and to connect the spots appearing on the feature in the 3D location in order to extract separate, respective contours of each of the elongate appendages in the set. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)

- 23. A computer software product, comprising a non-transitory computer-readable medium in which program instructions are stored, which instructions, when read by a processor, cause the processor to receive an image of a pattern of spots that has been projected onto a scene, which includes a feature having a set of elongate appendages, which have respective transverse dimensions that are less than twice an average distance between the spots in the pattern that is projected onto the feature, and to process the image in order to segment and find a three-dimensional (3D) location of the feature and to connect the spots appearing on the feature in the 3D location in order to extract separate, respective contours of each of the elongate appendages in the set.
