The invention relates to an
image analysis method for a spray freezing
coating effect based on Image J, which comprises the following steps of: 1) a picture acquiring process, namely shooting a tray filled with
inert carrier particles by using a high-definition camera, and storing the picture; shooting the no-load tray, and storing a picture; 2) an
image processing process: utilizing Image J
software to calculate a quantitative relation between the number of pixel points of the picture and
millimeter, and setting the unit length of the picture;
cutting out a to-be-processed part in the picture; dividing the colors of the pictures into 256 types, and converting the
cut pictures into 8-bit pictures by utilizing Image J
software; converting the 8-bit pictures into a
binary image by utilizingImage J
software; counting an
image area ratio occupied by a black region in the
binary image to obtain a projection area of spray freezing
coating; and 3) a
coating effect analysis process; accordingto the present invention, the spray freezing coating picture shot by the
high definition camera is processed and analyzed to obtain the
inert carrier particle
surface coating effect, the result is reliable, accurate and objective, the operation is simple, and the implementation is easy.
