The invention discloses a 3D stereo-imaging capsule endoscope system based on structured light. The system comprises a capsule shell body, a controller, a light emission sub-system, an illumination device, an imaging sub-system and a capsule positioning sub-system, wherein the controller, the light emission sub-system, the illumination device, the imaging sub-system and the capsule positioning sub-system are disposed inside the capsule shell body; a signal control output end for the light emission sub-system of the controller is connected to a signal input end of the light emission sub-system; an illumination light signal control output end of the controller is connected to a signal control input end of the illumination device; an imaging signal output end of the imaging sub-system is connected to an imaging signal input end of the controller; and a positioning information communication end of the capsule positioning sub-system is connected to a positioning information communication end of the controller. The system disclosed by the invention has the advantages that information inside an alimentary canal can be displayed in an all-round manner; and a doctor can make diagnosis more accurately and effectively.
Description
technical field [0001] The invention relates to the technical field of medical equipment, in particular to a structured light-based 3D imaging capsule endoscope system and method. Background technique [0002] The existing wireless capsule endoscope enters the digestive tract through human oral intake, and the peristalsis of the digestive tract provides power for it to move in the digestive tract, thereby completing the shooting of the digestive tract image, and transmitting it to the outside of the body through a wireless transmission system for display. [0003] The images obtained by wireless capsule endoscopes widely used in the market are only two-dimensional and static, and cannot clearly display the real situation of the three-dimensional images in the digestive tract in all directions. In response to this problem, the Chinese patent "Virtual Reality Capsule Endoscope" with the patent publication number CN104720735A has designed a capsule endoscope. The capsule endosc...
