An apparatus for object detection around a vehicle includes an imaging device mounted on the vehicle and a computing device. The imaging device is used to capture a video of an exterior environment of the vehicle. The computing device is used to execute a DSFPN module in order to provide a DSFPN model detector, which functions as a perception unit to process and analyze the video captured by the imaging device and to estimate a scale, a location and categories of an object. The DSFPN model detector includes a bottom-up subnet provided with auxiliary prediction heads, and a top-down subnet provided with prediction heads. When the DSFPN model detector is performed in a model training stage, both the prediction heads and the auxiliary prediction heads are used. In a detection stage, only the prediction heads are used in the DSFPN model detector, and the auxiliary prediction heads are removed.

Apparatus, system and method for object detection around vehicle and application of same

Apparatus and method for measuring physiological information of a living subject in a vehicle are provided. The apparatus includes an illumination unit configured to emit light at a wavelength and illuminate a region of interest (ROI) of the living subject with the emitted light; a light sensing unit configured to remotely acquire signals of light in a range of wavelengths reflected from the ROI of the living subject responsive to the illumination; a remote photoplethysmography (PPG) extraction unit configured to extract PPG signals from the acquired signals of light; a PPG processing unit configured to process the extracted PPG signals in the form of vital signs and subsequently determine a physical and psychological status of the living subject according to the vital signs; and a control unit configured to activate the illumination unit in a time-varying pattern and to activate the light sensing unit accordingly.
