3D time-of-flight active reflective sensing system and method

Abstract

Systems and methods provide for identifying a dynamic object in an enclosed space and the presence of a component at a first location. The system uses an active electro-optic 3D sensor, such as a three-dimensional time-of-flight camera, to identify the presence or absence of reflected pulses to determine, for example, proper seat belt placement, or to identify changes in the characteristics of reflected pulses to determine, for example, changes in the position of the living thing and thus determine the possible movement of said living thing.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to and is incorporated by reference into U.S. Provisional Patent Application 62 / 431,185, filed December 7, 2016 and entitled "3D Time of Flight ActiveReflecting Sensing Systems and Methods." technical field [0003] The present disclosure relates to the monitoring of non-line-of-sight areas of vehicles by active optical sensors and optical reflective integration, and more particularly, to the use of time-of-flight reflective sensing systems to detect changes in reflected images to detect the presence of moving objects. Background technique [0004] Systems for detecting a child seated in a child seat have been developed and tested, where the sensing system is integrated directly into the child seat structure, as indicated in a recent NHTSA report (DOT HS 812 187, July 2015) . These systems are based on the detection of child seats by several sensing mechanisms including pressure, force...

Problems solved by technology

All of the above methods can be prone to incorrect classifications due to clothing, due care, blocking obstacles, occupant lack of movement, etc.

In addition, many of these systems depend on sensing the projected location of the occupant and cannot account for the separation of the occupant from the sensed location
