Methods and systems for positioning robots and adjusting postures

A system for positioning a robot, comprising:

• a storage device, configured to store a computer instruction;
• and
• a processor connected to the storage device, wherein when executing the computer instruction, the processor causes the system to perform the following operations:
• causing the robot to adjust an image capturing apparatus installed on the robot to a first target posture;
• obtaining a first image and a second image including a face of a target object, the first image being captured using the image capturing apparatus at the first target posture, and the second image being captured using a medical imaging device;
• determining at least one target region corresponding to at least one target portion of the target object from the first image, wherein the at least one target portion is a static facial region that is less affected by changes in facial expressions than other facial portions;
• and
• determining positioning information of the robot based on the at least one target region and the second image.

A non-transitory computer readable medium, comprising executable instructions that, when executed by at least one processor, direct the at least one processor to perform a method, the method comprising:

• causing a robot to adjust an image capturing apparatus installed on the robot to a first target posture;
• obtaining a first image and a second image including a face of a target object, the first image being captured using the image capturing apparatus at the first target posture, and the second image being captured using a medical imaging device;
• determining at least one target region corresponding to at least one target portion of the target object from the first image, wherein the at least one target portion is a static facial region that is less affected by changes in facial expressions than other facial portions;
• and
• determining positioning information of the robot based on the at least one target region and the second image.
