Abstract
Systems and methods are provided for monitoring an enclosure that is transported by a vehicle. The system may include a mmWave device configured to direct mmWave signals into the enclosure, at least one camera configured to capture an image of the enclosure, and a lighting device configured to direct light into the enclosure when the at least camera captures the image of the enclosure. The system may further include at least one processor configured to read out and execute instructions stored in at least one memory to perform a monitoring operation wherein the processor controls the mmWave device, the camera, and the lighting device.
Claims18
A system for monitoring an enclosure that is transported by a vehicle, the system comprising:
- a mmWave device configured to direct mmWave signals into the enclosure and receive mm Wave signals reflected back to the mmWave device;
- at least one camera configured to capture an image of an interior of the enclosure;
- and
- at least one processor configured to read out and execute instructions stored in at least one memory to perform a monitoring operation wherein the at least one processor (i) processes the mmWave signals that are reflected back and received by the mmWave device to determine if there is a moving object in the interior of the enclosure and (ii) directs the at least one camera to capture the image of the interior of the enclosure when it is determined that there is no moving object in the interior of the enclosure,
- wherein, in the monitoring operation, the at least one processor (i) determines a distance from the mm Wave device to one or more objects in the interior of the enclosure, (ii) determines if there is a change in one or more objects in the interior of the enclosure by comparing the distance from the mm Wave device to the one or more objects in the interior of the enclosure to a previously determined distance from the mmWave device to one or more objects in the interior of the enclosure, and (iii) directs the at least one camera to capture the image of the interior of the enclosure when it is determined that there is no movement in the interior of the enclosure and that there has been a change in one or more objects in the interior of the enclosure, and
- wherein, when determining the distance from the mmWave device to one or more objects in the interior of the enclosure, the processor (i) obtains a coordinate representation of a geometry of the interior of the enclosure, (ii) calculates points corresponding to one or more objects in the coordinate representation, (iii) corrects points corresponding to the one or more objects in the coordinate representation to be inside the geometry of the interior of the enclosure that are initially calculated to be outside the geometry of the interior of the enclosure due to mmWave signals reflected from surfaces of the interior of the enclosure, (iv) filters out points that remain outside of the geometry of the interior of the enclosure after the correction, (iv) compares the calculated points of one or more objects in the coordinate representation to a previous calculation of points of one or more objects in the coordinate representation to determine if there has been a change in distance from the mm Wave device to the one or more objects in the interior of the enclosure.
A system for monitoring an enclosure that is transported by a vehicle, the system comprising:

- at least one camera configured to capture an image of an interior of the enclosure;
- and
- at least one processor configured to read out and execute instructions stored in at least one memory to perform a monitoring operation wherein the at least one processor (i) processes the mmWave signals that are reflected back and received by the mm Wave device to determine if there is a moving object in the interior of the enclosure and (ii) directs the at least one camera to capture the image of the interior of the enclosure when it is determined that there is no moving object in the interior of the enclosure,
- wherein, in the monitoring operation, the mmWave device directs two chirps of the mmWave signals with less than 500 microseconds between the chirps.
