Abstract:
A method and a system for remote sharing annotation trajectory in a three-dimensional space are provided. In response to activating a first electronic apparatus to display a first space, the first electronic apparatus obtains a first reference point of a designated object presented in the first space. After the first electronic apparatus displays the first space, the first electronic apparatus detects a three-dimensional movement trajectory of a target object in the first space, detects inflection point information of the three-dimensional movement trajectory and captures a diameter of the three-dimensional movement trajectory, and then sends the inflection point information and the diameter to a second electronic apparatus. In response to activating the second electronic apparatus to display a second space, the second electronic apparatus reconstructs the three-dimensional movement trajectory based on the inflection point information and the diameter, and presents the three-dimensional movement trajectory in the second space based on a second reference point relative to the first reference point.
Abstract:
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.
Abstract:
