摘要： The present invention provides a sampling capsule and a sampling capsule system. The sampling capsule includes an enclosure, a partition wall arranged in the enclosure, and a sample chamber enclosed by the partition wall and the enclosure at a first side of the partition wall. The sampling capsule further includes an inner sample inlet on the partition wall, an outer sample inlet, a sampling tube and a switch assembly. The outer sample inlet is on the enclosure at a second side of the partition wall. The sampling tube connects the outer sample inlet and the inner sample inlet, and the switch assembly clamps or unclamps a portion of the sampling tube. When sampling is needed, the switch assembly unclamps the sampling tube to sample liquid. When sampling ends, the switch assembly tightly clamps the sampling tube to prevent sample liquid leak or contamination.

摘要： A control method and a control system for a capsule endoscope are provided. The control method comprises acquiring a frame rate of the capsule endoscope. The frame rate is the number of frames of images captured by the capsule endoscope per unit time. The control method further comprises controlling the number of radio frequency transmission channels that are turned on according to the frame rate. The number of radio frequency transmission channels that are turned on is at least two, and the radio frequency transmission channels transmit the captured images. The control method and control system for the capsule endoscope can adaptively distribute a plurality of radio frequency transmission channels according to the real-time position of the capsule endoscope, and further turn on the radio frequency transmission channels to transmit a plurality of signals synchronously or asynchronously.

摘要： A method for measuring objects in digestive tract based on an imaging system is provided. The imaging system enters a calibration stage, and obtains a calibration image. A measurement stage enters, and the imaging system places in the digestive tract to capture at least one detection image. The depth distance zi from each pixel in the detection image to the imaging system is calculated, and it records as a depth image z(x, y). The scale r of each pixel in the detection image is calculated according to the depth image z(x, y). The actual two-dimensional coordinates Si′ of each pixel point in the detection image are calculated by the scale r, and the actual three-dimensional coordinates (Si′, z(x, y)) of each pixel are obtained. The distance between any two pixels in the detection image or the area within any range is calculated.

摘要： A method for measuring objects in a digestive tract based on an imaging system is provided. The imaging system captures a detection image in the measurement stage. The depth distance zi from a target point P′ to a board is calculated, a correction factor is obtained according to the predicted brightness g−1(zi) of a reference point P in the detection image. The depth image z(x, y) from the actual position of each pixel to the board is calibrated by the correction factor. The scale r of each pixel is calculated according to the depth image z(x, y). The actual two-dimensional coordinates Si′ of each pixel are calculated by the scale r, and the actual three-dimensional coordinates (Si′, z(x, y)) of each pixel are obtained. The distance between any two pixels in the detection image or the area within any range are calculated.
