    摘要: Disclosed are a scene video switch system and a scene video switch method. The system comprises an input unit configured to input an image currently captured by a video capture unit to serve as a current image; a detection unit configured to detect all of interesting elements and latent elements in the current image so as to determine a maximum possible existing area of the interesting elements; a state switch unit configured to carry out, by using a predetermined finite state machine, switching between scene states of the maximum possible existing area according to predetermined different scene states and switching conditions; and a display unit configured to extract, based on a current scene state switched by the state switch unit, an area of concern coinciding with the current scene state from the maximum possible existing area to serve as a scene video for display.

    摘要: An image processing method include projecting first and second images which are captured by two fisheye lenses onto first and second hemispherical projection models, respectively; determining a set of waiting-for-stitching surface region pairs on the first and second hemispherical projection models; extracting feature points from the two fisheye images and determining feature points matching each other to serving as pixels matching each other; determining a set of surface region pairs including the pixels matching each other on the first and second hemispherical projection models as the set of waiting-for-stitching surface region pairs; generating a customized projection model on the grounds of the set of waiting-for-stitching surface region pairs by letting a spherical distance between vertexes of each pair in the set of waiting-for-stitching surface region pairs be zero; and generating a third image by projecting the first and second images onto the customized projection model.

    摘要: Three dimensional image fusion method and device are disclosed. The method includes steps of obtaining a spherical image and a two dimensional image; projecting the two dimensional image onto a planar surface predetermined in a spherical coordinate system where the spherical image is located, so as to acquire a projected image having a predetermined number of feature points on the spherical surface corresponding to the spherical image; determining multiple mapping points on the spherical surface which correspond to the predetermined number of feature points, letting the predetermined number of feature points superpose on the multiple mapping points, respectively, and carrying out spatial coordinate conversion, so as to attain a converted image; and mapping multiple points except the predetermined number of feature points in the converted image onto the spherical image based on a predetermined mapping relationship, so as to fuse the two dimensional image onto the spherical image.

    摘要: A person counting method and a person counting system are provided. The method includes extracting a group of person images to obtain a first image set; dividing the first image set into first and second subsets based on whether a related image exists in a second image set, and reusing a person ID of the related image; estimating posture patterns of images in the first subset, and storing the images in the first subset into an image library based on person IDs and the posture patterns; and selecting a target image whose similarity to an image in the second subset is highest from the image library, reusing a person ID of the target image when the similarity is greater than a threshold, and assigning a new person ID and incrementing a person counter by 1 when the similarity is not greater than the threshold.
