Curling trajectory data. Specifically, analyze the real-time video stream of camera C1, analyze the current position of the curling stone, the movement speed of the current curling stone, and the movement angle parameters of the current curling stone, and generate the current curling stone of a single stroke. The curling trajectory data is used as the basic data for user scoring, and the hitting data is passed to the interactive scoring service module. Among them, as shown in Figure 4, the curling field is a standard rectangular area. By establishing a two-dimensional coordinate system, the curling field is mapped to the coordinate system, where the X-axis represents the width of the curling field (0<X<5000) , the Y-axis represents the length of the field (0<Y<30176, in this plan, Y=0 represents the forward throw line of the curling field). Real-time detection of the position (x, y), moving speed v and moving direction θ (the angle between the movement direction and the θ). By discretely sampling the continuous data of a single hit, and counting the data of athletes' word hits, we can obtain multiple triples of the current hitting curling motion data corresponding to the single hit, thereby forming the current hitting curling data. The motion trajectory data of the pot.
其中，获取所述实时视频流中的第一图像帧和第二图像帧，所述第二图像帧为所述第一图像帧之后间隔预设时长的图像帧；分别获取所述第一图像帧和所述第二图像帧中的当前击打冰壶的位置；根据所述第一图像帧和所述第二图像帧中的当前击打冰壶的位置及所述预设时长，确定所述第一图像帧中所述当前击打冰壶的位置、运动速度及运动角度，从而得到当前击打冰壶的运动三元组数据((x,y),v,θ)。具体地，当前击打冰壶的运动三元组数据((x,y),v,θ)的计算方式如下：Wherein, the first image frame and the second image frame in the real-time video stream are obtained, and the second image frame is an image frame separated by a preset time length after the first image frame; the first image frame is obtained respectively and the current position of the curling stone in the second image frame; according to the current position of the curling stone in the first image frame and the second image frame and the preset duration, determine the The position, movement speed and movement angle of the current curling stone described in the first image frame are thus obtained to obtain the movement triplet data ((x, y), v, θ) of the current curling stone. Specifically, the current motion triplet data ((x, y), v, θ) of the curling stone is calculated as follows:
对于连续的两帧图像，分别记录为第一图像帧I0和第二图像帧I1，时间戳分别为T0和T1，二者间隔的预设时长为T1-T0。通过分别对第一图像帧I0和第二图像帧I1进行边缘检测，从而确定两帧图像中当前击打冰壶的位置，分别记录为(x0,y0),(x1,y1)，故第一帧图像的速度和角度分别采用如下公式计算：For two consecutive frames of images, they are respectively recorded as the first image frame I0 and the second image frame I1 , the time stamps are T0 and T1 respectively, and the preset time interval between the two is T1 -T0 . By performing edge detection on the first image frame I0 and the second image frame I1 respectively, the current position of the curling stone in the two frames of images is determined, which are respectively recorded as (x0 , y0 ), (x1 , y1 ), so the speed and angle of the first frame of the image are calculated using the following formulas:
因此，根据上述计算，可以得出第一帧图像I0中当前击打冰壶的运动三元组数据描述为((x0,y0),v0,θ0)。Therefore, based on the above calculation, it can be concluded that the motion triplet data of the current curling stone in the first frame image I0 is described as ((x0 , y0 ), v0 , θ0 ).

其中，在获取用户模拟比赛操作信息后，根据所述模拟比赛操作信息，获取用户所击打冰壶的运动轨迹数据，根据所述当前击打冰壶的运动轨迹数据以及所述用户所击打冰壶的运动轨迹数据，确定所述用户比赛评分。具体地，本发明实施例预先建立了冰壶评分模型，冰壶评分模型用于计算用户击打与运动员击打的拟合度。通过冰壶评分模型来确定当前击打冰壶的运动轨迹数据以及所述用户所击打冰壶的运动轨迹数据的拟合度，从而确定用户的比赛评分。Among them, after obtaining the user's simulated game operation information, according to the simulated game operation information, the movement trajectory data of the curling stone hit by the user is obtained. According to the movement trajectory data of the current curling stone hit by the user and the The curling trajectory data is used to determine the user's competition score. Specifically, the embodiment of the present invention pre-establishes a curling scoring model, and the curling scoring model is used to calculate the degree of fit between the user's hitting and the player's hitting. The curling scoring model is used to determine the fitting degree of the motion trajectory data of the current curling stone and the motion trajectory data of the curling stone hit by the user, thereby determining the user's game rating.
通过冰壶评分模型来确定当前击打冰壶的运动轨迹数据以及所述用户所击打冰壶的运动轨迹数据的拟合度的具体过程为：以冰壶运动场地的远端前掷线为分割，将所述用户所击打冰壶的运动轨迹数据切分为第一用户运动轨迹数据及第二用户运动轨迹数据；以冰壶运动场地的远端前掷线为分割，将所述当前击打冰壶的运动轨迹数据切分为第一当前运动轨迹数据和第二当前运动轨迹数据；根据所述第一用户运动轨迹数据、所述第二用户运动轨迹数据、所述第一当前运动轨迹数据及所述第二当前运动轨迹数据，以及对应的拟合度权重，计算所述当前击打冰壶的运动轨迹数据以及所述用户所击打冰壶的运动轨迹数据的拟合度；根据所述拟合度，确定所述用户比赛评分。由于冰壶运动中的场地特性，拟合计算过程中以远端的前掷线为分割，将用户所击打冰壶的运动轨迹数据分为两片，两片数据先独立计算拟合度，给予不同的权重值(离击打目标位置点越近，权重值越大)，得到最终的用户拟合度值。其中，本发明实施例并不限定该拟合度权重的具体数值，本领域技术人员可依据具体场景进行相应设置。The specific process of determining the fitting degree of the motion trajectory data of the current curling stone and the motion trajectory data of the curling stone hit by the user through the curling scoring model is: taking the far end throw line of the curling venue as Divide the motion trajectory data of the curling stone hit by the user into the first user motion trajectory data and the second user motion trajectory data; use the far end throw line of the curling venue as the segmentation, divide the current The motion trajectory data of curling is divided into first current motion trajectory data and second current motion trajectory data; according to the first user motion trajectory data, the second user motion trajectory data, the first current motion The trajectory data and the second current movement trajectory data, as well as the corresponding fitting degree weight, calculate the fitting degree of the movement trajectory data of the current curling stone and the movement trajectory data of the curling stone hit by the user; According to the degree of fit, the user competition score is determined. Due to the field characteristics of curling, the far end of the forward throw line is used as a segmentation during the fitting calculation process, and the motion trajectory data of the curling stone hit by the user is divided into two pieces. The two pieces of data are first independently calculated for the fitting degree. Different weight values are given (the closer to the hitting target position, the greater the weight value), and the final user fitness value is obtained. Among them, the embodiment of the present invention does not limit the specific value of the fitting degree weight, and those skilled in the art can make corresponding settings according to specific scenarios.
具体地，假设运动员的当前击打冰壶的运动轨迹数据的数据总量为C，则运动员的当前击打冰壶的运动轨迹数据表示为：Specifically, assuming that the total data amount of the athlete's current motion trajectory data of curling is C, then the athlete's current motion trajectory data of curling is expressed as:
{((x00,y00),v00,θ00)...((x0n,y0n),v0n,θ0n)}。{((x00 ,y00 ),v00 ,θ00 )...((x0n ,y0n ),v0n ,θ0n )}.
用户所击打冰壶的运动轨迹数据表示为：The movement trajectory data of the curling stone hit by the user is expressed as:
{((x10,y10),v10,θ10)...((x1n,y1n),v1n,θ1n)}。{((x10 ,y10 ),v10 ,θ10 )...((x1n ,y1n ),v1n ,θ1n )}.
则冰壶评分模型对总拟合度的计算，可以用如下公式表示：Then the calculation of the total fitting degree of the curling scoring model can be expressed by the following formula:
其中，S(((x,y),v,θ))表示总拟合度，该总拟合度反映用户比赛评分，λ0表示第一用户运动轨迹数据与第一当前运动轨迹数据的拟合度权重，S0表示第一用户运动轨迹数据与第一当前运动轨迹数据的拟合度，λ1表示第二用户运动轨迹数据与第二当前运动轨迹数据的拟合度权重，S1表示第二用户运动轨迹数据与第二当前运动轨迹数据的拟合度。Among them, S(((x,y),v,θ)) represents the total fitting degree, which reflects the user's competition score, and λ0 represents the approximate relationship between the first user's motion trajectory data and the first current motion trajectory data. Fit weight, S0 represents the fitting degree of the first user's motion trajectory data and the first current motion trajectory data, λ1 represents the fitting degree weight of the second user's motion trajectory data and the second current motion trajectory data, S1 represents The degree of fitting between the second user's motion trajectory data and the second current motion trajectory data.

m＝0，N＝[21946*C/30176]m＝0，N＝[21946*C/30176]
m＝1，N＝C-[21946*C/30176]m=1, N=C-[21946*C/30176]

运动员的当前击打冰壶的运动轨迹数据为：The athlete's current curling trajectory data is:
{((2500,10),2300,115),((2400,20),2250,115),((1250,22000),150,115),((1230,22100),140,115)}。{((2500,10),2300,115),((2400,20),2250,115),((1250,22000),150,115),((1230,22100),140,115)}.
将数据分片后，前两组数据为第一片，后两组数据为第二片，将数据代入公式计算：After the data is divided into pieces, the first two groups of data are the first piece, and the last two groups of data are the second piece. Substitute the data into the formula to calculate:
S0＝102.653,S1＝772.069。S0 =102.653, S1 =772.069.
将上述运算结果代入公式中，则用户比赛评分为：Substituting the above operation results into the formula, the user competition score is:
S＝0.3*102.653+0.7*772.069＝571.2442。S＝0.3*102.653+0.7*772.069＝571.2442.
