    • It is made possible to provide a deformable mirror apparatus which is deformable to a complicated shape (high-order shape). A deformable mirror apparatus includes: a substrate; a plurality of electrodes provided on the substrate; a spacer fixed above the substrate, having a first opening passing through from a first face of the spacer facing to the substrate to a second face of the spacer facing opposite from the first face, surrounding the electrodes, and having a step on the second face; a drive part including a membrane part disposed so as to cover the step of the spacer and so as to be opposed to the electrodes, a casing part having an opening at a bottom face of which the membrane part is exposed and supporting the membrane part, and a reflection film provided on the membrane part; and a voltage generator configured to generate predetermined voltage patterns on the electrodes, respectively.

    • It is possible to measure a 3-dimensional shape by using a projector and an imaging device without requiring calibration in advance. A pattern light is applied from a projector to an object and this is imaged by an imaging device to capture an image as an input. An in-camera parameter, an in-projector parameter, a parameter of positional relationship between the camera and the projector are estimated. By using the estimation results, a 3-dimensional shape of the object is measured. When a laser pointer is attached to the projector and a laser is applied to the object for capturing an image as an input, scaling of the object shape can also be estimated. Moreover, when measuring a plurality of objects or measuring the same objects a plurality of times, the accuracy of the 3-dimensional shape respectively obtained can be increased by simultaneously processing the inputs. Moreover, when one of projector and the camera is fixed and the other is moved while measuring the same object a plurality of times, the accuracy of the 3-dimensional shape obtained as a result can be increased by performing bundle adjustment.
    • 可以通过使用投影仪和成像装置来预测不需要校准来测量三维形状。 图案光从投影仪施加到物体,并且其由成像装置成像以捕获图像作为输入。 估计摄像机内参数,投影机内参数,相机与投影机之间的位置关系参数。 通过使用估计结果,测量物体的三维形状。 当激光指示器附接到投影仪并且激光被施加到物体以捕获图像作为输入时,也可以估计对象形状的缩放。 此外,当测量多个对象或多次测量相同的对象时,可以通过同时处理输入来分别获得所获得的三维形状的精度。 此外,当投影仪和相机中的一个被固定并且另一个在同时测量相同的对象的同时被移动时,通过执行束调整可以提高作为结果而获得的三维形状的精度。
