PURPOSE:To provide the shape detecting device capable of accurately detecting the picture position of an object even when the shape of the scanning window does not coincide with the shape of the picture of the object or even when the scanning position of a scanning window does not coincide with the position of the object. CONSTITUTION:The device is provided with a visual sensor 1, picture memory 2, position discrimination means 11 discriminating the position of the objective picture, edge point detecting means 12 having plural sampling line windows with proper length which detect the picture density at the position of the detected picture and detecting the edge point of the picture density on the sampling line window as the contour point of the objective picture, and shape setting means 12 setting the contour line of the objective picture from the contour line position. |
