In order to realize the size measurement of large forgings in thermal state; an online measurement method based on line laser scanning is proposed in the paper. The measurement system mainly consists of a line laser projector and a charge-coupled device (CCD) camera. The laser projector is driven by the stepper motor for scanning the forgings continuously; while real-time images are captured by the CCD to provide the information for further feature extraction. First of all; particle swarm optimization algorithm is utilized to reduce the optical distortion error between actual and ideal images as a kind of optimization method. Secondly; the preprocessing is carried out to improve the image quality of the hot parts; and further two-dimensional image information of the forgings is obtained bymeans of center extraction. Thirdly; the size of forgings is calculated through processing the data acquired by continuous scanning the forgings and the realtime shotting. Finally; the measurement of forgings on overall outside size is achieved. The method proposed in the paper is viable according to the experiment results. © Springer-Verlag London 2013;
