摘要： A computer-implemented image processing method for removing complex conjugate image data from image data in real-time using dispersion comprising receiving an image signal comprising image data including complex conjugate image data (902), performing baseline signal subtraction (906), resampling wavelength data to generate linear wavenumber image data (908, 910), processing the linear wavenumber image data to generate a complex conjugate resolved, CCR, result using at least one iteration of a CCR image processing algorithm (912), and computing a CCR image from the CCR result (914); and separating the resulting CCR image from the received OCT image data to remove the complex conjugate image data. The method may be performed in real-time and may use phase or magnitude data or a synthesis of the two when generating the image data from the CCR result.

摘要： A three-dimensional (3D) scanner, which is in communication with a display, includes one or more optical sensors. The scanner scans, using the one or more optical sensors, an object having a surface. The scanning generates data corresponding to a 3D shape of at least a portion of the surface of the object. The scanner generates a 3D reconstruction of the shape of the surface of the object. The scanner provides a preview of the 3D reconstruction of the at least portion of the shape of the surface of the object. The scanner provides, to the display, for rendering with the preview of the 3D reconstruction of the at least portion of the shape of the surface of the object, an indication of at least one of a quantity or a quality of the data corresponding to the 3D shape of the at least portion of the surface of the object.

摘要： A depth data measuring head (600, 700) comprising: a structured light projection apparatus (110, 610, 710) used for projecting, under the drive of a driving apparatus (114, 314) and at different projection angles, a beam having a texture to a measured space so as to form different textures on an object to be measured; and first and second image sensors (620, 630; 720, 730) that are respectively arranged on both sides of the structured light projection apparatus (110, 610, 710), the first and second image sensors having a predetermined relative spatial position relationship and imaging the measured space at least twice so as to obtain at least two sets of images having different texture distributions, wherein the at least two sets of images are used for obtaining single-measurement depth data of the object to be measured. The structured light projection apparatus (110, 610, 710) that reflects, at different angles, structured light generated by a light source module (I) is used, so that rapid, economical and low-failure-rate multi-pattern projection is implemented. Furthermore, the structured light projection apparatus (110, 610, 710) matches multiple pairs of binocular sensors (723, 724; 733, 734) sharing a light path, thereby further shortening the frame interval and improving the quality of depth fusion data. Also disclosed is a depth data computing device and measurement method.
