  • Patent number: 11335100
    Abstract: A traffic light recognition system including a map, a localization module, at least one image capturing device and an image processing module is provided. The map is configured to provide an information relevant to a traffic light. The localization module is configured to provide a positioning information relevant to the traffic light. At least one image capturing device is configured to capture a real-time road image relevant to the traffic light. The image processing module is configured to combine the map and the positioning information of the traffic light provided by the localization module to generate a region of interest in the real-time road image captured by the image capturing device, and to recognize the traffic light in the region of interest, wherein the traffic light includes a light box and at least one light signal.

  • Patent number: 10242575
    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.

  • Patent number: 10192287
    Abstract: An image processing method is adapted to process images captured by at least two cameras in an image system. In an embodiment, the image processing method comprises: matching two corresponding feature points for two images, respectively, to become a feature point set; selecting at least five most suitable feature point sets, by using an iterative algorithm; calculating a most suitable radial distortion homography between the two images, according to the at least five most suitable feature point sets; and fusing the images captured by the at least two cameras at each of timing sequences, by using the most suitable radial distortion homography.

  • Patent number: 10037597
    Abstract: An image inpainting method includes the following steps: segmenting image, acquiring a plurality of images, and having the plurality of images segment into noise-contained pixel images and non-noise-contained pixel images, and confirming the positions of every noise pixel of the noise pixel image; and performing inpainting in light of the noise-contained pixel images, finding out the offset map and geometric relationship of the pixel corresponding relationship without being subjected to the affection of noise and having the pixel corresponding relationship with minimum parallax, making use of the offset map or the geometric relationship to extract corresponding pixel that is not subjected to the affection of noise, performing inpainting and substituting the noise pixel in the plurality of images to generate at least a synthetic image without containing noise.
