Sprint timing portable equipment based on human body detection and pedestrian re-identification

Abstract

The invention relates to the technical field of sprint timing, and discloses sprint timing portable equipment based on human body detection and pedestrian re-identification. The sprint timing portableequipment comprises a fixed base and starting equipment, the bottom of the fixed base is fixedly connected with a plurality of rollers, and the upper surface of the fixed base is fixedly connected with two manual telescopic rods; the invention also provides a sprint timing method based on human body detection and pedestrian re-identification, and the method comprises the following steps: S1, building equipment: building camera equipment and timing equipment at a proper position away from a terminal line; s2, placing equipment, namely placing the starting equipment at the starting point line;s3, collecting information. The equipment is good in flexibility and convenient to carry, automatic line-passing identification and running timing are achieved through pedestrian detection and pedestrian re-identification algorithms, interference of human factors is eliminated, the cost is reduced, videos of the whole running process are recorded, and the traceability of detection results is improved.

Description

Technical field[0001]The invention relates to the technical field of sprint timing, in particular to a portable device for sprint timing based on human body detection and pedestrian identification.Background technique[0002]Sprinting is one of the track and field events, generally including: 50m run, 60m run, 100m run, 200m run, 400m run, 4×100m relay race, etc.; its sports characteristics are that people can run at the same time. The fastest speed, to complete the specified distance on the track and field track, and the first to finish the event as the winner. In terms of human energy supply, sprinting means that the human body maximizes the speed limit instinct of the human body and supplies energy through anaerobic metabolism.[0003]Existing running timing methods generally use a manual stopwatch. After the order is issued, the staff will perform the timing according to the watch. However, there will inevitably be errors in the timing. The manual stopwatch timing has a greater impa...
