1. A developed impact mark analysis apparatus comprising:
an image acquisition unit configured to receive at least one first image that is at least one photograph of impact marks developed by applying an amino acid reaction reagent, and a second image that is a photograph of impact marks at a crime scene, which are developed by applying an amino acid reaction reagent from evidence at the crime scene;
at least one memory storing computer program instructions; and
at least one processor configured to execute the computer program instructions to:
obtain at least one first outline image by outlining the at least one first image, and to obtain a second outline image by outlining the second image;
store the first outline image corresponding to related tool characteristic information in a database;
obtain a first thinned outline image and a second thinned outline image by thinning the first outline image and the second outline image, and determine whether the first outline image is matched with the second outline image by comparing the first thinned outline image with the second thinned outline image;
display the first outline image matched with the second outline image, the second outline image, and the related tool characteristic information on a display.
