Abstract
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 zfrom a target point P' to a board is calculated, a correction factor is obtained according to the predicted brightness g(z) 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 S′ of each pixel are calculated by the scale r, and the actual three-dimensional coordinates (S′, 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.
