車線変更車両の検出装置、方法及びビデオ監視装置

Japanese Patent JP7251409

B2

To provide a lane change vehicle detection device, method, and video monitoring device capable of reducing influence of shielding and reducing a calculation amount.SOLUTION: A lane change vehicle detection method includes: a step 101 for selecting multiple feature points on the basis of multiple frame images in a video and calculating optical flow vectors of multiple feature points in multiple frame images; a step 102 for filtering optical flow vectors on the basis of angles and magnitudes of optical flow vectors, and acquiring multiple optical flow vectors to match features of a lane change vehicle; a step 103 for taking statistics of multiple optical flow vectors after filtering, and acquiring distribution information in multiple frame images of the number of multiple optical flow vectors; and a step 104 for determining one or multiple lane change vehicles in multiple frame images on the basis of distribution information.SELECTED DRAWING: Figure 1
