Systems and methods for error correction in structured light

An apparatus for error correction in structured light, comprising:

• means for receiving a structured light image of at least a portion of a composite code mask encoding a plurality of codewords, the image including an invalid codeword;
• means for detecting the invalid codeword;
• means for generating a plurality of candidate codewords based on the invalid codeword;
• means for selecting one of the plurality of candidate codewords to replace the invalid codeword;
• means for generating a depth map for an image of the scene based on the selected candidate codeword
• means for generating a digital representation of a scene based on the depth map;
• and
• means for outputting the digital representation of the scene to an output device.

A non-transitory computer-readable medium storing instructions for error correction in structured light, the instructions when executed that, when executed, perform a method comprising:

• receiving, via a receiver sensor, a structured light image of at least a portion of a composite code mask encoding a plurality of codewords, the image including an invalid codeword;
• detecting the invalid codeword;
• generating a plurality of candidate codewords based on the invalid codeword;
• selecting one of the plurality of candidate codewords to replace the invalid codeword;
• generating a depth map for an image of the scene based on the selected candidate codeword;
• generating a digital representation of a scene based on the depth map;
• and
• outputting the digital representation of the scene to an output device.
