摘　　要：An approach,known as Edge Tracking Method,has been developed in particular,which searches out the outer edge and the central spot edge of the coherent image of a particle.The processing procedure of the digital images and its program have been worked out in detail.Finally,the outer size and the central size a particle image are determined by means of the presented technique,then the particle size and its position are calculated by means of the Three-Dimensional Judgement Technique.The results obtained are reasonable.An approach,known as Edge Tracking Method,has been developed in particular,which searches out the outer edge and the central spot edge of the coherent image of a particle.The processing procedure of the digital images and its program have been worked out in detail.Finally,the outer size and the central size a particle image are determined by means of the presented technique,then the particle size and its position are calculated by means of the Three-Dimensional Judgement Technique.The results obtained are reasonable.
