Abstract: The disclosure relates to a method, device and storage medium for processing a target track. According to an embodiment, the method comprises: determining a candidate customer track set of a receipt data group corresponding to one of a plurality of shopping receipts; counting, for each track, the number of sold items matching the track in location in a sold item set indicated by the receipt data group, as a first location matching count of the track; counting, for each track, the number of sold items matching track points of interest in a set of track points of interest of the track in location in the sold item set, as a second location matching count of the track; and determining a customer track corresponding to the receipt data group based on first location matching counts and second location matching counts of a plurality of tracks in the candidate customer track set.

Abstract: A method for multi-target multi-camera tracking includes: performing multi-target tracking on a video captured by each of multiple cameras, to extract a tracklet for each target appearing in the video, wherein multiple tracklets for multiple targets are extracted on the basis of multiple videos; extracting a feature for each tracklet; determining orientation of each tracklet based on orientation of the target relative to the camera; dividing the multiple tracklets into multiple groups based on the determined orientations; performing clustering on tracklets in each group based on the extracted features, such that tracklets corresponding to the same target are aggregated into an initial set; performing merging among initial sets obtained by performing clustering on respective groups, such that tracklets corresponding to the same target and having different orientations are merged into a final set; and using the tracklets in the final set as tracking information for the corresponding target.

Abstract: A self-locking connection device is provided, which includes a housing, a sliding block and a buckle which are mounted in the housing. The sliding block slides back and forth along the housing and is locked in case that the sliding block is pushed to a front side, and is unlocked and reset in case that the sliding block is pushed to the front side again. An inclined wall for supporting the buckle is provided inside the housing, a height of the inclined wall gradually decreases from front to rear, the buckle is connected to the sliding block to move along the inclined wall with the sliding block, and the buckle is locked at a top end and protrudes out of the opening in case that the sliding block is locked at the front side.

Abstract: A method for using pins in different mode during different time is provided. The method is able to make at least one pin of a SOC be used in a first interface mode or a second interface mode during different time; wherein the SOC comprises a first interface circuit, a first pin, a second interface circuit, and a second pin; the first interface circuit comprises a first bidirectional PAD unit, a first signal interface unit of the first interface mode and a interface unit of the second interface mode; the second interface circuit comprises a second bidirectional PAD unit, a second signal interface unit of the first interface mode. The method comprises: selecting the output of the first signal interface unit or the output of the interface unit of the second interface mode to be connected with the first pin through the first bidirectional PAD unit during different time.
