Method and device for processing scan image of three-dimensional scanner

A scan image processing method performed by an electronic device, which comprises at least one processor and at least one memory configured to store commands to be executed by the at least one processor, the method comprising:

• generating a three-dimensional image of a shape of an oral cavity by the at least one processor based on an image acquired from a three-dimensional scanner;
• displaying a screen comprising a first region on a display by the at least one processor, at least the three-dimensional image being displayed in the first region;
• receiving, by the at least one processor, a user input for selectively recording a predetermined region of the screen;
• and
• generating, by the at least one processor, a video image by recording a region of the screen corresponding to the user input in response to the user input,
• wherein the recorded region comprises a portion of the first region, and
• wherein the scan image processing method further comprises:
• detecting, by the at least one processor, a tooth in the image acquired from the three-dimensional scanner;
• starting, by the at least one processor, recording a region corresponding to the user input in response to detecting the tooth, and
• stopping, by the at least one processor, recording when the tooth is not detected in the image acquired from the three-dimensional scanner for a predetermined time while recording the region corresponding to the user input.

A non-transitory computer-readable recording medium recording commands which, when executed by at least one processor, cause the at least one processor to perform an operation, wherein the commands cause the at least one processor to:

• generate a three-dimensional image of a shape of an oral cavity based on an image acquired from a three-dimensional scanner;
• display, on a display, a screen comprising a first region in which at least the three-dimensional image is displayed;
• receive a user input for selectively recording a predetermined region of the screen;
• and
• generate a video image by recording a region of the screen corresponding to the user input in response to the user input,
• wherein the recorded region comprises a portion of the first region, and
• wherein the commands further cause the at least one processor to:
• detect a tooth in the image acquired from the three-dimensional scanner;
• start recording a region corresponding to the user input in response to detecting the tooth, and
• stop recording when the tooth is not detected in the image acquired from the three-dimensional scanner for a predetermined time while recording the region corresponding to the user input.

A system for three-dimensional scanning, comprising:

• a three-dimensional scanner comprising an input device and configured to scan a shape of an oral cavity;
• and
• an electronic device communicably coupled to the three-dimensional scanner,
• wherein the electronic device comprises:
• a communication circuit communicatively connected to the three-dimensional scanner;
• an input device;
• a display;
• and
• at least one processor,
• wherein the at least one processor is configured to:
• generate a three-dimensional image of the shape of the oral cavity based on an image acquired from the three-dimensional scanner via the communication circuit;
• display, on the display, a screen comprising a first region in which at least the three-dimensional image is displayed;
• receive a user input for selectively recording a predetermined region of the screen;
• and
• generate a video image by recording a region of the screen corresponding to the user input in response to the user input,
• wherein the recorded region comprises a portion of the first region, and
• wherein the electronic device detects a tooth in the image acquired from the three-dimensional scanner, starts recording a region corresponding to the user input in response to detecting the tooth, and stops recording when the tooth is not detected in the image acquired from the three-dimensional scanner for a predetermined time while recording the region corresponding to the user input.
