Embodiment Construction
[0030] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0031] The recognition method of the target paper image provided by the embodiment of the present invention includes: detecting the target paper image to be tested, obtaining the outer contour parameters of multiple target rings in the target paper image to be tested, and recording them as target target ring parameters; The image of the target paper is obtained by photographing the target paper to be measured; when an arrow body target is detected on the image of the target paper to be measured, the arrow parameters of the arrow body target are obtained; according to the arrow parameters and the target ring parameters Obtains the value of the bull's-eye hit by the arrow target.
[0032] The present invention provides a recognition method of a target paper image, by detecting the target paper image to be tested obtaine...

The invention discloses a target paper image identification method, which comprises the following steps: detecting a target paper image to be detected, obtaining outer contour line parameters of a plurality of target rings in the target paper image to be detected, and recording the outer contour line parameters as target ring parameters; wherein the to-be-detected target paper image is obtained byshooting to-be-detected target paper; when an arrow body target is detected on the to-be-detected target paper image, obtaining arrow parameters of the arrow body target; and according to the arrow parameters and the target ring parameters, obtaining a target ring value in the shooting process of the arrow body target. The invention further discloses a target paper image recognition device and system and a storage medium. According to the method, image correction does not need to be carried out on the to-be-detected target paper image, the shot to-be-detected target paper image is directly detected, the target ring value in the arrow target beam is further obtained, and the accuracy is high.
Description
technical field [0001] The present invention relates to the technical field of image processing, in particular to a target paper image recognition method, device, system and storage medium. Background technique [0002] In archery competitions, training and entertainment venues, traditional artificial target reporting methods are mostly used. Its workload is heavy, safety is poor, efficiency is low, also is not easy to understand archery situation in real time. Therefore, the machine automatic target reporting technology came into being. Among them, the archery automatic target reporting method based on video stream has been focused on because of its advantages of simple installation, convenient mobile use and so on. This method is mainly to process the target paper image obtained by video acquisition, so as to obtain the required information for automatic target reporting. [0003] Since the image of the target paper obtained by video shooting will produce geometric dist...
