摘要： An apparatus and a method for dual mode depth measurement are provided. The apparatus is used for measuring a depth information of a specular surface in a depth from defocus (DFD) mode or measuring a depth information of a textured surface in a depth from focus (DFF) mode. The apparatus includes a light source, a controller, a processor, a lighting optical system, an imaging optical system, a beam splitter and a camera. The controller is for switching between the depth from defocus mode and the depth from focus mode. The lighting optical system is used to focus a light from the light source on an object surface in the depth from defocus mode, and the lighting optical system is used to illuminate the object surface with a uniform irradiance in the depth from focus mode.

摘要： An object recognition system based on machine learning includes a 2D image capture module, a 3D space capture module, a data selection module, a data alignment module, a feature capture module and a detection module. The 2D image capture module captures a 2D image. The 3D space capture module captures 3D point cloud data. The data selection module performs object segmentation and depth recognition to select at least one region of interest (ROI). The data alignment module maps coordinates of the at least one ROI to coordinates of the 2D image. The feature capture module calculates features of the 2D image and extracts at least one feature of interest corresponding to the coordinates of the ROI from the features of the 2D image. The detection module obtains the feature of interest and identifies at least one object in the 2D image according to the feature of interest.

摘要： Measurement system and method for measuring multi-dimensions of an object are provided. A two-dimensional (2D) image capturing device captures at least one macro-2D image of the object. A three-dimensional (3D) information acquisition device acquires micro-3D measured data of the object. A integration and estimation device performs 2D and 3D image correction on macro-2D image and micro-3D measured data to map micro-3D measured data into macro-2D image to output 3D-topography data corresponding to macro-2D image of the object, and based on machine learning mechanism, performs matching procedure on at least one connection feature between any two positions in 3D-topography data with a database to elect an adapted model. Based on its corresponding to at least one fitting function, the integration and estimation device estimates the connection features of 3D-topography data to output at least one estimated feature amount, thereby obtaining measurement results corresponding to the object.
