A shape profile measurement device includes: a light projector and a light receiver arranged facing each other; a belt conveyor for conveying an object for measurement; and a calculation unit. The light projector includes a plurality of light-emitting portions arranged in an array direction, and each emits substantially parallel measurement light. The light receiver includes a plurality of light-receiving portions arranged in the array direction facing the plurality of light-emitting portions, and each receives the measurement light emitted from a corresponding light-emitting portion. The light-receiving portions output a signal indicating a light intensity of the received measurement light. The calculation unit acquires the signal of the light receiver when the object is at a plurality of different movement-direction positions between the light-emitting portions and the light-receiving portions, and obtains a shape profile on the basis of the signal acquired and information relating to the plurality of movement-direction positions.

The present invention relates to a method of determining the coherence between a physical object and a numerical model representative of the shape of a physical object, wherein a specific use of the method according to the invention is assessing and quantifying manufacturing defects. The method is characterized by a set of steps comprising: capturing multiple images of the physical object; processing the images to produce a second numerical model of the physical object; in a computer, aligning the first numerical model and the second numerical model to generate a third numerical model according to specific sub-steps, wherein the third numerical model comprises a plurality of points representative of the shape of the captured physical object. Compared with the first numerical model, the third numerical model allows determining a measurement of the coherence between the physical object captured by means of images and the first numerical model representative thereof.
