Tower crane video monitoring system with automatic tracking and zooming functions and monitoring method

Abstract

The invention discloses a tower crane video monitoring system with automatic tracking and zooming functions, and the invention also discloses a tower crane video monitoring method with automatic tracking and zooming functions. The method comprises the following implementing steps of taking a marker on a crane hook as a tracking target image, and detecting the area and the center of mass of an object at real time by the image processing technology to realize the automatic zooming and tracking, image sequence acquisition, target characteristic extraction, target characteristic match and target search location; and aiming at swaying in the running process of the tower crane, combining a color histogram with form features, and then improving the present mean shift tracking algorithm which is based on the distribution of a target color histogram according to the real operating condition of the tower crane, thereby realizing the target tracking under the environment of the tower crane. The invention has automatic camera zooming and tracking functions so that a tower crane operator can watch the lifted objects and the circumferential situation thereof clearly in a control room at real time .

Description

technical field [0001] The invention belongs to the technical field of measurement, control and monitoring, and relates to a tower crane video monitoring system with an automatic tracking and zooming function, and also relates to a tower crane video monitoring method with an automatic tracking and zooming function. Background technique [0002] Tower cranes (hereinafter referred to as tower cranes) belong to high-altitude operation equipment. The operating room is located at the top of the tower crane. During the working process, tower crane operators often cannot see the ground conditions clearly. In order for the tower crane to complete the required operations, ground commanders are generally required Cooperate with the tower crane operator, and the tower crane operator operates the crane according to the instructions of the commander. Under this mode of operation, on the one hand, if the commanders have a weak sense of responsibility and insufficient personal ability, saf...
