Abstract
The present invention discloses a system for wireless capsule endoscope with adaptive frame rate, comprising: a recorder data processor to filter the first posture information of a capsule endoscope and the second posture information of a portable recorder to obtain a quaternion p0 of the first posture information and a quaternion p1 of the second posture information, and to calculate an interpolated median s0 between p0 and p1 at time t0, and an interpolated median s1 between p′0 and p′1 at time t1; the recorder data processor also calculates a difference diff0 between the interpolated median s0 and s1, and works out the dot product of the difference diff0 and unit quaternion [1, 0, 0, 0].
