Title: Method for detecting three-dimensional position attitude of circle feature, device for executing the method and medium recording software for realizing the method
Inventor: FUJIWARA NOBUYUKI
IPC: G06T7/60
Filed: 1999-08-19
Abstract: PROBLEM TO BE SOLVED: To detect the three-dimensional position attitude of a circle feature such as hole or end point of cylindrical portion of an industrial component by calculating the circle feature while defining the sequence of points of an edge line segment, which is the source of an extracted circular arc, as sequence of circle candidate points in the limit of an install state in which the hole of an object component to be detected is not almost inclined with respect to the optical axis of a camera. SOLUTION: In the limit of the install state in which the hole of the object component to be detected is not almost inclined with respect to the optical axis of the camera, when extracting a circular arc feature, a circular arc extracting part 110 defines only the circular arc settled within a set radius range as a circular arc feature. The range of the circular arc radius is preset by a circular arc radius range calculating part 20 while using a similar relation and that value is stored in a memory 30. An extracted circular arc circle candidate point sequence setting part 120 sets the sequence of points of the edge line segment, which is the source of the extracted circular arc, as the sequence of circle candidate points. On the basis of the set sequence of circle candidate points, a circle feature data calculating part 40 calculates the circle feature. Thus, even when oil or dust is stuck on the surface of the component, the portion to become the circle can be extracted.

Filed: 1993-08-27
Abstract: PURPOSE:To record information for magnetic recording while suppressing influence of heat on a substrate to the minimum by forming a heat insulating layer between a substrate and a magnetic recording layer to prevent thermal diffusion from the magnetic recording layer to the substrate even when the magnetic recording layer is heated. CONSTITUTION:Either the magnetic material in a first magnetic recording layer 4a or the magnetic material in a second magnetic recording layer 4b which constitute the magnetic recording layer 4 has higher coercive force and lower Currie temp. Tc than the other. In this medium, during magnetic recording is performed while heating, the distribution of temp. increase concentrates in the magnetic recording layer having a high coercive force and a low Currie temp. which is the upper second magnetic recording layer 4. Since diffusion of heat to the magnetic recording layer having a low coercive force and a high Currie temp. which is the lower first magnetic recording layer 4a is little, the Currie temp. of the first magnetic recording layer 4a is designed rather low and damages due to heat can be decreased.
