The invention relates to a method and device for orienting an umbilicated fruit, in which, during a first orientation phase (22), the presence of at least a portion of an umbilicus is detected in at least one initial image (II), then the fruit is driven (24) in spinning rotation about a first axis of rotation at an angular amplitude of between 5° and 45°, and then the presence of at least a portion of an umbilicus is detected in at least one subsequent image (IU). If at least a portion of an umbilicus is detected in at least one initial image (II) and no longer detected in each subsequent image (IU), the first orientation phase is stopped and the method is continued.

A shape inspection apparatus includes N illumination light sources, a line sensor camera, a measurement control unit, and a data processing unit. The measurement control unit controls the illumination light sources to modulate luminescence intensities at a frequency that is 1/N of a frequency of a scan rate of the line sensor camera, and to emit lights by sequentially repeating N different patterns of illumination intensity ratios. The data processing unit generates a first separated image and a second separated image based on a photographed image, generates a first mixing elimination image acquired by removing an unnecessary illumination component from the first separated image, and a second mixing elimination image acquired by removing an unnecessary illumination component from the second separated image, and calculates an inclination of the surface of the strip-shaped body based on a difference between the first mixing elimination image and the second mixing elimination image.
