1. A method of analyzing a tool trace, the method being performed by a portable tool trace analyzing apparatus comprising a camera unit and comprising:

  • obtaining a first image that is a three-dimensional (3D) image of the tool trace;

    displaying the first image on a screen;

    storing, in a database, second images that are 3D images of one or more tools and that correspond to a plurality of pieces of feature information of the one or more tools;

    when a specific tool is selected based on a user input, searching for a second image from among the second images in the database, the second image corresponding to the specific tool, and displaying the second image on the screen;

    matching the second image that is selected with the first image and thus generating a match image;

    displaying the match image on the screen;

    wherein the generating of the match image comprises;

    calculating an error between the first image and the second image;

    when the calculated error is greater than a preset reference value, the tool trace is not determined to match the specific tool, and when the calculated error is equal to or less than the preset reference value, the tool trace is determined to match the specific tool; and

    displaying a result of the determination on the screen;

    wherein the feature information of the one or more tools comprises at least a shape of a tool head; and

    wherein the generating of the match image further comprises generating the match image by matching a head part of the tool in the second image, with the first image.
