Abstract

Embodiments of the invention disclose a capsule endoscope system and a distance measuring method for a capsule endoscope. The capsule endoscope system according to an embodiment of the invention comprises the capsule endoscope, a magnetic ball and a distance measuring device, wherein the capsule endoscope comprises a housing and an imaging element located in the housing; the imaging element shootsan image of the cavity wall at a predetermined position of a cavity by using automatic exposure parameters; the magnetic ball is used for controlling the position and the posture of the capsule endoscope in the cavity by adopting magnetic force so as to reach the predetermined position; and the distance measuring device is used for acquiring the automatic exposure parameters from the capsule endoscope to obtain the distance between the predetermined position and the inner wall of the cavity. According to the capsule endoscope system and the distance measuring method for the capsule endoscopein the embodiments of the invention, the distance to be measured can be conveniently and rapidly obtained.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a capsule endoscope system and a distance measuring method for the capsule endoscope. Background technique [0002] Endoscopes are used to detect the health status of the stomach and esophagus, which can help doctors make accurate diagnoses, and are increasingly used in the medical field. In the process of in vivo detection, it is very important for the doctor to know the position of the endoscope and the shooting area to know the distance parameter between the endoscope and the site to be measured (for example, the stomach wall). [0003] In the prior art, the endoscope uses a time of flight (TOF) method for distance measurement. figure 1 A schematic diagram of a measuring principle of a distance measuring device according to the prior art is shown. Such as figure 1 As shown, a distance measuring device (TOF chip) 10 is provided on the endoscope, including a laser...
