Abstract: The present disclosure provides a device and method for depth sensing by utilizing the combination of a ranging sensor and an image sensor. The ranging sensor can accurately detect distance measurement from an object. The image sensor can take images with high resolution of the object. By combining each sensor data from the ranging sensor and the image sensor, accurate depth information with high resolution of the object may be obtained. A structured light having patterned shapes are used in conjunction with the ranging sensor to receive reflected patterned shapes of the object. These reflected patterned shapes are used to analyze distance measurements associated with the specific patterned shapes. These distance measurements from both the ranging sensor and the image sensor is aligned and combined to generate an accurate depth map with high resolution using a processor of an electronic device including the ranging sensor and the image sensor.

Abstract: A method and apparatus for determining space occupancy and performing volumetric measurement of a transportation system using a time-of-flight (TOF) sensor array are provided. In the method and apparatus, the TOF sensor array, which is mounted in a transportation system and includes a plurality of TOF sensors, outputs a plurality of distance measurements made by the plurality of TOF sensors, respectively. In the method and apparatus, a map of one or more objects positioned in the transportation system is generated based on the plurality of distance measurements. The map is output for display to a user by a display.
