    摘要: Techniques to determine a search range for a stereo based matching pyramid. A first disparity estimation value for a first level in a stereo based matching pyramid based on an image may be received. A search range for a second level may be determined using the first disparity estimation value. The search range based on a pyramid level of a second level may be increased. The search range may be increased based on a pyramid level of the second level. A second disparity estimation value may be selected from the search area for the second level. A depth map for the second level may be determined based on the second disparity estimation value. Other embodiments are described and claimed.

    摘要: Systems and methods may provide for projection of a plurality of structured light patterns. In one example, the method may include generating a low-resolution pattern image utilizing a returned image, wherein the low-resolution pattern image is an approximation of an image that would have been generated utilizing a low-resolution pattern and generating a high-resolution pattern image utilizing a preprocessed returned image and a preprocessed low-resolution pattern image, wherein high-resolution pattern image is an approximation of an image that would have been generated utilizing a high-resolution pattern.

    摘要: Systems and methods may include utilizing a structured light pattern that may be, among other things, decoded in the three directions (e.g., vertical, horizontal, and diagonal). In one example, the method may include detecting a first feature of a target image in a return image, designating a feature type of the first feature, and an index with the letter, wherein the index is associated with the pattern slide. The method may also include calculating a horizontal position in the pattern slide of the first feature, calculating a vertical position in the pattern slide of the first feature, and calculating a depth of the first feature.
