Abstract:
The present invention provides an augmented reality imaging-based sightseeing guide apparatus which easily matches the augmented reality image visualized on the reality of outdoor environment. An embodiment of the apparatus includes a camera part outputting video data corresponding to the reality of an arbitrary sightseeing place; a display part displaying the augmented reality image visualized on the reality of the sightseeing place; and a controller detecting a natural marker in the reality of the sightseeing place on the basis of the image data and controlling the display part to visualize the augmented reality image at the location of the natural marker.
Abstract:
PURPOSE: A pedestrian detection method of a pedestrian detection device is provided to perform pedestrian detection on a search window using a second classifier with high accuracy after reducing the number of search windows, thereby performing highly accurate detection of an object while reducing the complexity of detection procedure and power consumption. CONSTITUTION: A pedestrian detection device obtains an image from a digital image device and performs blocking of search windows(210,220). The pedestrian detection device selects a specific block from blocks determined by a pre-learned classifier(230) and produces a specific vector of HOG features from the selected block(240,250). The pedestrian detection device calculates a SVM(Support Vector Machine) response value using the produced feature vector, and performs a first object detection by applying the response value to an AdaBoost Classifier(260,270). If a pedestrian is detected at the first object detection, the pedestrian detection device performs a second object detection to the search window(280).
