Embodiment Construction
[0014] Preferred embodiments of the present invention are described below, and it should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.
[0015] According to an embodiment of the present invention, a method for acquiring football sports images is provided, including:
[0016] ⑴In the sky above the football field, there are multiple groups of rotating cameras that move up and down in the preset ladder according to the 360-degree rotation direction. Each group of cameras contains 3 cameras; the 3 cameras in each group of cameras work according to the preset working order ;
[0017] When one of the three cameras fails to work properly due to a fault, the next working camera immediately and seamlessly switches to the working state, and an alarm mechanism is activated to notify the crew to repair or replace the faulty camera within a preset time period ;...

The invention discloses a method for obtaining football moving images. The method comprises the steps of: (1) arranging a plurality of groups of cameras over a football match field in a rotary manner; and (2) transmitting images shot by the plurality of groups of cameras to a background controller in real time. A controller carrying out row and column segmentation contrast on the images transmitted in real time; when interrupted images or images with a definition low than a preset threshold are found, a gradient algorithm is immediately started for remediation, and the rotation speeds and the lifting speeds of the plurality of groups of cameras are remotely controlled. By adopting the method for obtaining football moving images, the defects in the prior art such as high manual labor amount, high cost and poor reliability are overcome, and the advantages of low manual labor amount, low cost and good reliability are realized.
Description
technical field [0001] The present invention relates to the technical field of electronic products, in particular to a method for acquiring soccer sports images. Background technique [0002] The purpose of the football game is to shoot the football into the opponent's goal as much as possible. Every time a ball is scored, one point can be obtained. When the game is over, the team with the most points wins. If the score is the same within the specified time of the game, it depends on the rules of the game, and the game can be divided in the form of drawing lots, overtime rematch or mutual penalty kicks. [0003] In football matches, except that the goalkeeper can use his hands to touch the football in his own penalty area, each player on the field can only use other parts of his body other than his hands to control the football. Football motion images include displacement-time images and velocity-time images, wherein both displacement and velocity are vectors, and vectors c...
