A recently granted patent (Publication Number: US11772563B2) describes an in-vehicle multi-monitoring device designed to enhance safety and security in vehicles. The device includes two imaging members, each capturing images of the occupants in the vehicle from different angles or imaging ranges. The first imaging member captures images at shorter intervals, while the second imaging member captures images at longer intervals, ensuring that one image from each member is captured simultaneously for every multiple images captured by the first member.

The device is controlled by a controller that receives the images from both imaging members and executes different processes based on the captured images. The first process involves using the images from both members to acquire parallax information between them or determine the seated position of the driver. The second process, on the other hand, uses only the images from the first member to determine the state of the driver, such as inattentiveness, drowsiness, or emergency. The images from the second member are used to determine the state of each occupant, including their seated position, posture, wearing of seat belts, presence of a child restraint seat, or emergency situations.

To ensure accurate imaging, the first member captures images of the driver's upper body or head, while the second member captures images with a wider angle, including both the driver and other occupants in the vehicle. The controller also executes a correction process to reduce any differences in angle of view or imaging range between the two imaging members.

The device offers multiple types of processes, including binocular processes based on both images and monocular processes based on either the first or second images. The first imaging member is positioned at a greater distance from the driver compared to the second imaging member.

Overall, this in-vehicle multi-monitoring device provides comprehensive monitoring of both the driver and occupants, allowing for improved safety and security in vehicles.
