[0047] In specific implementation, a method for detecting the sedimentation velocity of fine sand based on image grayscale includes the following steps:
[0048] a. Obtain a detection device with the following structure. The detection device includes a settlement vessel, a light source, a camera, and a computer. The settlement vessel is made of transparent material and has a rectangular cross section. The light source is located on one side of the settlement vessel and has a height and settlement. The containers are consistent, the camera is located on the other side of the settlement container and is used to collect images of the settlement container, and the computer is connected to the camera;
[0049] b. Carry out gray-concentration calibration. When calibrating, use the above-mentioned detection device to configure the sediment solution of different concentrations in the sedimentation container, stir it evenly, turn on the light source and the camera to collect the image, and u...
