Imaging system for capturing oblique images from vehicles
The patent US12063443B2 describes an advanced imaging system designed for installation on vehicles, including aerial vehicles. The system features a first camera that captures oblique images along a designated scan path, utilizing a scanning mirror structure with at least one mirror surface. This mirror structure is driven to rotate about a scan axis, with the scan angle being adjusted based on the vehicle's yaw angle. The first camera's optical axis is set at an oblique angle to the scan axis, allowing it to focus an imaging beam reflected from the scanning mirror onto its image sensor. The processing circuitry plays a crucial role in determining the scan angle by considering the difference between the vehicle's yaw angle and a preferred yaw angle, which is typically set to zero.
Additionally, the imaging system may include a second camera that captures a second set of oblique images along a different scan path, also utilizing the scanning mirror structure. The design allows for simultaneous reflection of imaging beams to both cameras, enhancing the system's efficiency. The processing circuitry can also correct the scan angle based on the vehicle's yaw, ensuring accurate image capture. Furthermore, the system may incorporate a stabilization platform to mitigate roll and pitch movements, although it does not correct for yaw. This innovative imaging system is particularly beneficial for applications requiring precise imaging from vehicles, such as aerial surveillance or mapping.
