Deposit detection method and device and computer readable storage medium

Abstract

The invention discloses a deposit detection method and device and a computer readable storage medium. The detection method comprises the following steps: acquiring three-dimensional point cloud data of a scene to be detected; mapping the three-dimensional point cloud data to a horizontal plane to obtain two-dimensional point cloud data; performing clustering processing on the two-dimensional point cloud data according to corresponding height information in the three-dimensional point cloud data to obtain sub-point cloud data of different deposits in the scene to be detected; according to the respective sub-point cloud data of the different deposits, determining respective size information of the different deposits; and according to the respective size information of the different deposits, determining whether to give an alarm prompt or not. The deposit detection method provided by the invention can accurately detect the deposit, is suitable for any scene, and is high in reusability.

Description

technical field [0001] The present application relates to the technical field of image processing, and in particular, to a method, device and computer-readable storage medium for detecting deposits. Background technique [0002] In places with high crowd density, such as schools, shopping malls, and stations, unobstructed access is the first element to ensure personnel safety. However, in daily life, people often ignore the importance of smooth passages. People often pile up sundries, including electric vehicles, cardboard, and waste chairs, on corridors, stair entrances, and elevator entrances. Under normal circumstances, as long as the passage is not completely blocked, the regular movement of a small number of people will not be affected in any way, but once danger occurs, it will inevitably cause a large number of people surging, then the passages accumulated by debris will be seriously affected. to the speed of evacuation of personnel, which is likely to cause danger. ...

AI Technical Summary

Problems solved by technology

Under normal circumstances, as long as the passage is not completely blocked, the regular movement of a small number of people will not be affected in any way, but once a danger occurs, it will inevitably cause a large number of people to surge, so the passages accumulated by debris will seriously affect to the evacuation speed of personnel, which is likely to cause danger

In addition to passage areas, for open areas such as squares, roads, and playgrounds, the accumulation of debris is more likely to be ignored by people, but the problems caused by occupying such public areas are many and dangerous, and they also deserve our attention.
