Multiple view transportation imaging systems
First Claim
1. A method of monitoring traffic using a single camera device, the method comprising:
- capturing a first image of a vehicle using the camera device, wherein the first image displays the vehicle from a first optical perspective comprising one of a vertical perspective and a lateral perspective;
capturing a second image of the vehicle using the camera device, wherein the second image displays the vehicle from a second optical perspective, wherein;
the second optical perspective comprises a different one of the vertical perspective and the lateral perspective of the vehicle than the first optical perspective; and
the second optical perspective is obtained via reflection off of a surface external to the camera device; and
determining characteristics of the vehicle by analyzing the first image and the second image.

Abstract
A camera may be positioned to have a direct view of on-coming vehicle traffic from a first perspective. Additionally, a reflective surface, such as a mirror, may be positioned within the viewing area of the same camera to provide the camera with a reflected view of vehicle traffic from a second perspective. The images recorded by the camera may then be received by a computing device. The computing device may separate the images into a direct view region and a reflected view region. After separation, the regions may be analyzed independently and/or combined with other regions, and the analyzed data may be stored. The regions may be analyzed to determine various vehicle characteristics, including, but not limited to, vehicle speed, license plate identification, vehicle occupancy, vehicle count, and vehicle type.

17. A method of monitoring traffic using a single camera device, the method comprising:
-
capturing a first image of a vehicle at a first time using the camera device, wherein the first image displays a first portion of the vehicle from a first optical perspective; and capturing a second image of the vehicle at a second time using the camera device, wherein the second image displays a second portion the vehicle from a second optical perspective, wherein; the second time differs from the first time; and the second portion of the vehicle differs from the first portion of the vehicle; causing a surface external to the camera device to change from one of a reflective state to a transparent state and a transparent state to a reflective state such that; the first optical perspective is obtained via a direct view through the surface during the first time; and the second optical perspective is obtained via reflection off of the surface during the second time; wherein the camera device and the surface maintain static positions between the capturing of the first image and the capturing of the second image; determining one of a license plate identification and a speed of the vehicle by analyzing the first image; determining a different one of a license plate identification and a speed of the vehicle by analyzing the second image; and associating the determined license plate identification of the vehicle with the determined speed of the vehicle.

18. A method of monitoring traffic using a single camera device, the method comprising:
-
capturing a first image of a vehicle using the camera device, wherein the first image displays the vehicle from a first optical perspective that provides the camera device with a view of one of a top portion, a front portion, a rear portion, and a side portion of the vehicle; and capturing a second image of the vehicle using the camera device, wherein the second image displays the vehicle from a second optical perspective, wherein; the second optical perspective provides the camera device with a view of a different one of the top portion, the front portion, the rear portion, and the side portion of the vehicle than the first optical perspective; and the second optical perspective is obtained via reflection off of a surface external to the camera device; and determining characteristics of the vehicle by analyzing the first image and the second image. - View Dependent Claims (19)
