This paper describes an approach for high-performance image retrieval method named interlaced fast sequential matching and its application to mechanical drawing processing. Conventional image retrieval methods for a huge image such as Correlation Matching and SSDA have a shortcoming with their performance.Thus, we use the interlaced fast sequential matching with rotation process in order to avoid the difficulties in the conventional methods. If we can find an efficient method to retrieve any drawing objects without OCR process, the more efficient management of old mechanical drawings can be performed. We first discuss some essential issues to be considered in mechanical drawing processing. Experimental results by using the proposed method are also described. The good performance of the proposed method is shown.
