The invention relates to a steel plate size measuring method, and belongs to the technical field of
steelmaking methods. According to the technical scheme, the method comprises the following steps: acquiring a video in a camera by using a camera function; the
image processor realizes conversion from videos to pictures; preprocessing the image; marking the outline of the image steel plate; training a user-defined steel plate
data set through a YOLOv8
algorithm; obtaining a steel plate contour; calculating the steel plate length. The method has the advantages that the advanced YOLOv8
algorithm in
machine learning is used for training the self-defined steel plate image
data set, on the premise that the steel plate is recognized, the contour, the length and the position information of the steel plate can be accurately obtained, and therefore the traffic collision accident caused by manual judgment errors is effectively avoided, and the traffic safety is improved. The
operation safety and the production efficiency of the
heating furnace are greatly improved, and the equipment loss and the potential production stagnation risk are reduced.
