Other AbstractThe invention claims a based on video image movement of the grain of grain loading state method and device for detecting method comprises: Through colour digital camera car to transport grain collects the image to obtain grain tank inlet and grain plane of the colour image; Using smoothing the edge of beeline detecting and filter processing on the surface of the colour image to obtain grain bin of the opening of the whole edge contour; Using colour space conversion and threshold value segmentation on image processing method so as to obtain the grain bin on the grain in the image area; Using two-dimensional convex pack algorithm to obtain grain representative area on the edge of convex point respectively and calculating these convex point to the grain bin of four edges of straight line distance; According to real time measurement of these distance through the preset threshold value judging whether the grain the grain box opening each distributed position of the loading state it realizes harvester vehicle to move grain unloading the grain loading state of the detecting. The grain state and corresponding operation indication of real time displaying the detecting terminal. The invention has convenient installation and maintenance and it is easy to operate and the detecting speed is quick the stability is strong the precision is high the advantage of.
