To improve automotive active safety and guarantee the safety of pedestrians at night time, a fast pedestrian detection method based on monocular far-infrared camera for driver assistance systems is proposed. According to the distribution of gray-level intensity of pedestrian samples, an adaptive local dual threshold segmentation algorithm is executed first to extract candidate regions. The presented...
This paper proposed an approach to process unstructured text query. The approach applies domain ontology in converting unstructured text to structured one. Then it uses ontology mapping technology in the knowledge searching process. It builds relationship between the structured text and cases in the knowledge base. In this way, the cases that match the condition expressed by the query text can be...
In order to improve the measurement precision for visual measure system, research on the influence of stereovision structure is presented based on binocular vision. A structure parameter model of binocular visual measure system is investigated with the trigonometric method. Through analyzing the measure accuracy of measuring point in binocular visual measure system, the effect of the structure parameters...
