Abstract: The present disclosure provides a light field imaging system by projecting near-infrared spot in remote sensing based on a multifocal microlens array. The light field imaging system includes a near-infrared spot projection apparatus (100) and a light field imaging component (200), where the near-infrared spot projection apparatus (100) is configured to scatter near-infrared spots on a to-be-observed object to add texture information to a target image, and the light field imaging component (200) is configured to image a target scene light ray with additional texture information. The present disclosure can extend a target depth-of-field (DOF) detection range, and particularly, reconstruct a surface of a weak-texture object.

Abstract: A temperature control method for vehicle seat heating includes: when turning on or switching to a heating level, determining a heating period at present according to a temperature value corresponding to a current Negative Temperature Coefficient (NTC) sensor, the heating period including an initial heating stage, an approaching stage and a steady stage; and segmentally controlling the on-off of a seat heating apparatus according to a heating strategy corresponding to each heating period, so that the seat surface temperature reaches to and stabilizes at an expected target temperature of the level. Further disclosed are a corresponding temperature control apparatus for the vehicle seat heating and a temperature control system for the vehicle seat heating. By adopting the temperature control method for the vehicle seat heating, the seat surface temperature can quickly reach to and stabilize at the expected temperature value, and thus the use experience of a user is improved.
