Distance measuring device, distance measuring method, program, electronic apparatus, learning model generating method, manufacturing method, and depth map generating method

A distance measuring method implemented by a distance measuring device that performs distance measurement, the distance measuring method comprising:

• receiving signals from a light receiving unit configured to acquire depth information;
• determining, based on depth values acquired by the light receiving unit, whether or not a difference in depth value between a first pixel in a depth map and a second pixel adjacent to the first pixel is larger than a first threshold;
• determining whether or not a difference in confidence between the first pixel and the second pixel is larger than a second threshold, when a difference in distance between the first pixel and the second pixel is determined to be larger than the first threshold;
• and
• confirming the first pixel to be a defective pixel, when the difference in confidence between the first pixel and the second pixel is determined to be larger than the second threshold.

A non-transitory computer readable medium storing a program, the program being executable by at least one processor to perform operations comprising:

• receiving signals from a light receiving unit configured to acquire depth information;
• determining, based on depth values acquired by the light receiving unit, whether or not a difference in depth value between a first pixel in a depth map and a second pixel adjacent to the first pixel is larger than a first threshold;
• determining whether or not a difference in confidence between the first pixel and the second pixel is larger than a second threshold, when a difference in distance between the first pixel and the second pixel is determined to be larger than the first threshold;
• and
• confirming the first pixel to be a defective pixel, when the difference in confidence between the first pixel and the second pixel is determined to be larger than the second threshold.
