Motion guiding method and motion guiding apparatus
First Claim
1. A motion guiding method, comprising:
- disposing a linear light source on a reference surface-facing side face of an arm piece of a main body at a distance above a reference surface, the main body being in contact with the reference surface;
projecting, by the linear light source, a reference light line on the reference surface and a direct light line on an outer surface of the main body, wherein one edge of the outer surface of the main body is adjacent to the reference surface;
capturing an image by an image-capturing module, with the image showing the reference light line, the direct light line, and a reflected light line, wherein the reflected light line is a reflection of the direct light line on generated by the direct light line striking the reference surface;
computing a reference angle formed between the reference light line and the reflected light line shown in the image to obtain a relative angle between the image-capturing module and the linear light source; and
moving the image-capturing module based on the relative angle.

Abstract
A motion guiding apparatus includes a guiding device and a mobile unit. The guiding device includes a main body, an arm piece, and a linear light source. The main body is in connection with the arm piece and arranged on a reference surface. The linear light source is arranged on the arm piece and forms a reference light line on the reference surface and a direct light line on the main body. The mobile unit is capable of capturing an image showing the reference light beam, the direct light beam, and a reflected light line. The mobile unit can also compute an angle formed between the reference light line and the reflected light line to obtain a relative angle between the mobile unit and the linear light source, so as to move in accordance to the relative angle. A motion guiding method is also provided.

5. A motion guiding apparatus, comprising:
-
a guiding device comprising; a main body having a first end portion and a second end portion, the first end portion being in contact with a reference surface; an arm piece extending from the second end portion; and a linear light source disposed on a reference surface-facing side face of the arm piece, the light emitted by the linear light source projecting a reference light line on the reference surface and a direct light line on an outer surface of the main body with one edge of the outer surface being adjacent to the reference surface; and a mobile unit comprising; a moving module including a roller and a motor; an image-capturing module including a lens, a light-sensitive element and an image processor, for capturing an image of the reference light line, the direct light line, and a reflected light line, wherein the reflected light line is a reflection of the direct light line on the reference surface; and a computing module connected to the moving module and the image-capturing module, including a processor for computing a reference angle formed between the reference light line and the reflected light line shown in the image, so as to obtain a relative angle between the mobile unit and the linear light source such that the computing module drives the moving module to move based on the relative angle. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12)
