Embodiment Construction

[0088] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0089] Such as figure 1 as shown, figure 1 It is a system structure diagram of the moving vehicle tracking method based on corner point matching in the present invention;

[0090] The video image of the road area C captured by the monitoring camera D is transmitted to the embedded vehicle analyzer A, and the embedded vehicle analyzer A utilizes the embedded video written according to the operation flowchart of the corner matching-based moving vehicle tracking method of the present invention The image analysis program analyzes the captured video images in real time to detect and track the vehicle; if a vehicle is detected in the road area, the embedded vehicle analyzer A transmits the vehicle information to the back-end monitoring platform B; if the road area is not When a vehicle is detected, return to the first step of the process ...

Abstract

The invention discloses a moving vehicle tracking method based on corner matching. The moving vehicle tracking method comprises the steps of extracting corners of a detected region through a Harris algorithm according to a video image captured by a surveillance camera with a fixed field of view, calculating scale-invariant rotation feature transform descriptors of corresponding corners, matching the corners according to the scale-invariant rotation feature transform descriptors to form a track, performing calculation to obtain information such as a speed and a direction of the track, dynamically grouping the track, and performing reasonable judgment on a result obtained by initial grouping to determine a vehicle. By means of the moving vehicle tracking method based on corner matching, tracking of the vehicle is completed by performing matching tracking on the track and grouping the track. The moving vehicle tracking method based on corner matching can deal with effect of illumination variation of scenes and partial coverage of the vehicle on vehicle detection and tracking well.

Description

technical field [0001] The invention belongs to the field of pattern recognition, specifically relates to the technical field of intelligent transportation, in particular to a tracking method for moving vehicles based on corner point matching. Background technique [0002] With the progress of urbanization and the popularization of automobiles, the traffic volume of countries in the world has increased sharply. How to manage the operation and operation of roads and ensure the safe and fast driving of vehicles on roads has become an important issue in traffic management. Intelligent transportation The concept of vehicle detection and tracking has become a hotspot in intelligent transportation research. [0003] Currently commonly used vehicle detection and tracking methods mainly include: background difference detection method, vehicle model detection method and dynamic contour detection method. The background difference detection method is a classic motion detection method....
