摘要： The present disclosure discloses a method and apparatus for adjusting channelization of a traffic intersection. The specific implementation of the method is: obtaining (101) a first traffic characteristic of vehicles at each of a plurality of target positions in a process of vehicles in a target traveling direction traveling through the traffic intersection from upstream to downstream in a preset first time period; generating (102) first traffic change information of the traffic intersection based on the first traffic characteristic at each of the plurality of target positions; and in (103) response to that the first traffic change information satisfies a preset first change distribution, generating channelization adjustment information for non-motorized vehicle lanes of the traffic intersection. In this manner, the intelligent detection of an unreasonable traffic direction of channelization of the non-motorized vehicle is realized without manual work, and the efficiency of the channelization adjustment for the non-motorized vehicle lanes is improved.

摘要： A target detection method, device, an electronic apparatus, and a storage medium are provided, which relate to a field of computer vision technology. The method includes: determining at least one first image from a plurality of images, wherein a candidate target is contained in the at least one first image; acquiring confidence degrees of the candidate target in respective first images; calculating an appearance probability of the candidate target according to weights and the confidence degrees of the respective first image; determining the candidate target as a final target, in a case that the appearance probability meets a first preset condition. A candidate target may be comprehensively determined by using a detection result of a plurality of images, thereby determining a detected final target. Since not only a single image is used for detection to obtain a final target, the detection accuracy of the final target may be improved.
