    • Optical device and corresponding method for treasuring the dimensions of at least a three-dimensional object, which has a planar base expending in the x-z plane and the height extending in the y direction. The device comprises a supporting means, on which the object is positioned and which defines a surface in the x-z plane, at least an illuminating means for illuminating the object, a first inspection means comprising a first recording means for recording images of the object on a first sensor from an oblique direction at a prescribed angle of elevation with respect tc the plane of the supporting means. Finally, the device comprises a computing unit for collecting, processing and displaying the images of the object. In particular, the first inspection means comprises a first image reproducing optic for producing a geometrical distortion of the image, such that the resulting ratio height-to-width of the image is increased.
    • 用于珍贵至少三维物体的尺寸的光学装置和相应的方法,其具有在x-z平面上展开的平面基底和在y方向上延伸的高度。 该装置包括支撑装置,物体被定位在该支撑装置上,并且限定了xz平面中的一个表面,至少一个用于照亮物体的照明装置,第一检查装置,包括第一记录装置,用于将物体的图像记录在一个 第一传感器从倾斜方向以规定的仰角相对于支撑装置的平面相对于tc。 最后,该装置包括用于收集,处理和显示对象的图像的计算单元。 特别地,第一检查装置包括用于产生图像的几何失真的第一图像再现光学元件,使得所得到的图像的高宽比增加。
