20130156268 | IMAGE INFORMATION PROCESSING APPARATUS AND METHOD FOR CONTROLLING THE SAME - An image information processing apparatus performs three-dimensional measurement of an object using a captured image obtained by projecting onto the object a projection pattern containing a two-dimensional symbol sequence that is obtained by assigning a predetermined symbol to each code in a projection code string in which a plurality of types of codes are arranged two-dimensionally and capturing an image of the object. The apparatus obtains an imaging pattern by extracting a symbol sequence from the captured image, and converts symbol dots in the imaging pattern into corresponding codes, thereby obtaining an imaging code string. The apparatus obtains a predetermined number of codes according to one sampling feature selected from a plurality of types of sampling features, generates an information code string by arranging the obtained codes, and determining the correspondence between the information code string and a part of the projection code string, thereby performing three-dimensional measurement. | 06-20-2013 |
20130229666 | INFORMATION PROCESSING APPARATUS AND INFORMATION PROCESSING METHOD - A projection pattern that includes a measurement pattern for measuring a distance to a target object, and a code pattern for identifying the measurement pattern is projected onto the target object. The target object onto which the projection pattern was projected is sensed. On the basis of a relationship between the measurement pattern and the code pattern in the sensed image, the projection pattern that is to be projected onto the target object after the projection pattern are changed, the code pattern is read out in the sensed image of the target object onto which the changed projection pattern was projected, and the measurement pattern is associated with it. Using the associated measurement pattern, a distance from the projection unit or the sensing unit to the target object is acquired. | 09-05-2013 |
