Abstract: A parking guidance system and method and an automatic parking system. The method includes: detecting corners of a marked parking space; planning a vehicle's parking path based on the corners; and providing parking guidance based on the parking path. The planned parking path includes: a first straight path the vehicle will travel straight to a first turning point; a first turning path the vehicle will turn a first angle from the first turning point along the circumference of a first turning circle; a second straight path the vehicle will travel from the end point of the first turning path to a second turning point; a second turning path the vehicle will turn a second angle from the second turning point along the circumference of a second turning circle; and an intra-parking-space path the vehicle will travel from the end point of the second turning point to a stop point.

Abstract: A wide-angle lens calibration system is provided, which may include a rotation unit, an image input unit, and a processing unit. A lens to be calibrated may be disposed on the rotation unit; the rotation direction of the rotation unit may be parallel to the horizontal direction; the optical axis center of the lens may be aligned with a reference object. The image input unit may receive images from the lens. The processing unit may control the rotation unit to rotate and analysis the images received from the lens. The processing unit may execute a distortion calibration process, wherein the processing unit may continuously rotate the rotation unit by a predetermined angle and then record the distance between the position of the reference object in the image and the optical axis center and a total rotation angle after each rotation so as to establish a distortion calibration model.

Abstract: A marked parking space identification system and a marked parking space identification method are disclosed. The marked parking space identification method includes: receiving a first image of a first parking space with markings; identifying a plurality of corners in the first image of the first parking space with markings; pairing up two adjacent corners to become a parking corner group; and using the parking corner group to identify a first marked parking space.
