[0064] Example:

[0065] A method for calculating the setting of Chinese and Western dining tables, see Figure 1 ,include:

[0066] Obtain a camera to shoot the table after the contestant has finished setting the tableware to obtain the original image;

[0067] Identify objects in the original image; objects include condiment plates, dinner plates, soup bowls, chopstick holders, chopsticks, ladles, toothpicks, red wine glasses, white wine glasses, water glasses, table knives, fish knives, soup spoons, appetizer knives, decorative plates, dessert forks, dessert spoons, table forks, fish forks, appetizer forks, bread plates, and butter dishes;

[0068] Identify the location of an object;

[0069] Calculate the distance between any two objects, or between an object and the edge of a table;

[0070] The contestants' tableware settings are assessed based on the identified locations and distances.

[0071] In this embodiment, the method mainly includes the following steps:

[0072] 1) Collect the original image. Figure 2 , this method can install camera 1 above dining table 2, and camera 1 shoots dining table 2 from a bird's-eye view. The height of the camera can be adjusted according to the size of the dining table and the height of the tabletop from the ground, as long as it can shoot 30-50cm beyond the complete tabletop. When the dining table is for 10 people, this method supports 10 contestants to take the table setting assessment at the same time, and each contestant completes a set of table setting. When all 10 contestants have completed the table setting, the camera shoots the dining table to obtain the original image. The camera of this method can use a high-precision industrial array camera, so that high-definition pictures can be obtained.

[0073] 2) Tableware recognition. This method can identify the objects and positions of the original image through image recognition, target recognition, model matching and other technologies. This method can accurately identify objects in hundreds of Chinese and Western table settings, and can also identify the names and areas of the objects.

[0074] 3) Measurement data. This method calculates the distance from the object to the edge of the table and the distance between different objects based on the objects identified in the original image, replacing manual caliper measurement. The distance measurement error of this method is within 2 mm. This method can also connect the center points of different objects in the image, or the center point of the object to the edge of the table, and mark the measured distance to visualize the measurement results for user viewing.

[0075] 4) Assessment score. This method assesses the contestant's tableware setting according to the identified position and distance. When the tableware setting is close to the standard requirements, the contestant's assessment score is high. When the tableware setting does not meet the standard requirements, the contestant's assessment score is low.

[0076] In this embodiment, the method can also configure the specifications of the dining table and the recognition range of the object, so as to facilitate the accurate recognition and positioning of dining tables and objects of different specifications in the original image.

[0077] The method realizes automatic identification of dining tables and tableware, automatic calculation of assessment distance, and automatic completion of assessment based on the measurement results. It realizes automatic assessment of dining table settings in an intelligent, automated and precise manner, replacing the traditional method of measurement by the referee's naked eye and caliper, and overcoming the defects of measurement data deviation and non-objective scoring in traditional methods.

[0078] Furthermore, in some embodiments, after obtaining the original image and before identifying the object in the original image, the method further includes:

[0079] identifying an edge of a dining table in the original image;

[0080] The edge of the dining table is calibrated.

[0081] In this embodiment, the method also has the function of table positioning and calibration. The method can use a variety of ISP algorithms to quickly and efficiently identify the round table or square table in the original image and obtain the edge of the table. Figure 3 , Figure 3 The edge of the dining table is marked with a yellow line. Then the CCM and LSC algorithms are used to automatically calibrate the edge of the dining table. This method can also visualize the original image after recognition and calibration, so that personnel can view the positioning and calibration of the dining table in the original image. When this method detects that the dining table has deviated from its previous position due to movement, it recalibrates and positions the recognized dining table.

[0082] Furthermore, in some embodiments, identifying the object of the original image specifically includes:

[0083] Create object models for each type of object;

[0084] The original image is matched with the object model one by one to obtain the object of the original image.

[0085] In this embodiment, the method can create a corresponding object model according to the object to be identified. The object model identifies the area where the object is located and the name of the object. For example, object models corresponding to condiment plates, dinner plates, soup bowls, chopstick holders, chopsticks, long-handled spoons, toothpicks, red wine glasses, white wine glasses, water glasses, table knives, fish knives, soup spoons, appetizer knives, decorative plates, dessert forks, dessert spoons, dinner forks, fish forks, appetizer forks, bread plates, and butter dishes are created. The method matches the original image with the object models one by one. When a certain object model is matched in the original image, the area and name of the object are identified. For example, see Figure 4 , Figure 4 The yellow boxes are used to mark the condiment dishes, dinner plates, soup bowls, chopstick holders, chopsticks, toothpicks, etc. used in Chinese food. Figure 5 To identify table knives, fish knives, soup spoons, appetizer knives, decorative plates, dessert forks, dessert spoons, dinner forks, etc. used in Western cuisine.

[0086] In this embodiment, in order to improve the accuracy of object recognition. The method also needs to train the object model, such as setting different recognition thresholds, using visual learning, incremental training and other methods, using the object model to recognize objects in the image multiple times, and calculating mAP (mean average precision). When the calculated average precision reaches 99.8%, the object model can be stopped from being trained. When training the object model, the method can recognize objects in images taken over a long period of time and in large quantities, and enhance recognition accuracy.

[0087] Further, in some embodiments, see Figure 6 , the contestants' tableware setting will be assessed based on the identified distance, including:

[0088] Obtaining assessment standards; the assessment standards include a standard distance between two objects and a standard distance between an object and an edge of a dining table;

[0089] The distance is compared with the assessment standard respectively to obtain the distance deviation;

[0090] The assessment score is determined based on the distance deviation.

[0091] In this embodiment, when calculating the distance between two objects, the method can calculate the distance between the center positions of the two objects. When calculating the distance between an object and the edge of a dining table, the method can calculate the distance from the center position of the object to the edge of the dining table. The assessment criteria obtained by the method include the standard distance between two objects to be assessed, or the standard distance between an object to be assessed and the edge of a dining table. For example, the assessment criteria include 1.5 cm from the dinner plate to the edge of the dining table, 1 cm from the condiment plate to the dinner plate, 1.5 cm from the tail of the chopsticks to the edge of the dining table, 2 cm from the red wine glass to the condiment plate, 1 cm from the dessert fork to the decorative plate, 2 cm from the decorative plate to the edge of the dining table, 5 cm from the fish knife and the fish fork to the edge of the dining table, 0.5 cm from the appetizer fork and the dinner fork to the fish fork, and so on.

[0092] In this embodiment, the method compares the calculated distance with the standard distance to calculate the distance deviation, where the distance deviation can be a positive value or a negative value. When the distance deviation is small, it means that the table is more standard, and the obtained assessment score is high. When the distance deviation is large, it means that the table is not standard, and the obtained assessment score is low.

[0093] Further, in some embodiments, after obtaining the original image, see Figure 7 , also includes:

[0094] Create a dining chair model;

[0095] Match the original image with the dining chair model to obtain the dining chair and its center position in the original image;

[0096] Determine the center of the tableware based on the positions of all objects in each tableware set;

[0097] Compare the center position of the tableware with the center position of the dining chair to obtain the center position deviation;

[0098] The assessment score is determined based on the center position deviation.

[0099] In this embodiment, the method can also automatically assess the position of the dining chair and the position of the tableware. The method can create a dining chair model based on the dining chair, and the dining chair model identifies the area where the dining chair is located. Then the method matches the original image with the dining chair model to identify all the dining chairs and their center positions in the original image. Then the center position of the tableware is determined based on the position of all objects in each set of tableware. One of the contestants completes the table setting of a set of tableware. A set of tableware is used by one person. For example, each set of Chinese tableware includes Figure 4 Each set of Western tableware includes a dish, a dinner plate, a soup bowl, a chopstick holder, a pair of chopsticks, a toothpick, etc. Figure 5 The method can determine the location of each set of tableware according to the locations of all objects in the set of tableware, and determine the center position of each set of tableware according to the location of each set of tableware.

[0100] In this embodiment, the method then compares the center position of the tableware with the center position of the dining chair to obtain the center position deviation, and determines whether the center of the tableware is aligned with the center of the dining chair based on the center position deviation. For example, the center position of the dining table and the center position of the tableware are connected to obtain a first line segment, and the center position of the dining table and the center position of the dining chair are connected to obtain a second line segment. The angle between the first line segment and the second line segment is the center position deviation. When the center position deviation is less than the threshold, it means that the center of the tableware is aligned with the center of the dining chair, otherwise it is not aligned. The smaller the center position deviation, the higher the assessment score.

[0101] Further, in some embodiments, see Figure 8 , the contestants' tableware sets are assessed based on the identified positions.

[0102] Identify the names of all objects in each set;

[0103] Judging by the position of each object: whether the condiment dish in each set is located directly above the dinner dish, whether the soup bowl is located to the left of the condiment dish and in a straight line with the condiment dish, whether the chopstick holder is located to the right of the dinner dish and located at the upper third of the chopsticks, whether the toothpick is located between the long-handled spoon and the chopsticks, whether the red wine glass is located directly above the condiment dish, whether the white wine glass is located to the right of the red wine glass, whether the water glass is located to the left of the red wine glass, whether the table knife, fish knife, soup spoon, and appetizer knife are located to the right of the decorative plate, whether the dessert fork and dessert spoon are located directly above the decorative plate, whether the table fork, fish fork, and appetizer fork are located to the left of the decorative plate, whether the bread plate is located to the left of the appetizer fork, and whether the butter dish is located above the bread plate;

[0104] The assessment score is determined based on the judgment results.

[0105] In this embodiment, the method can also automatically assess the position of each object in the tableware. The method first identifies the names of all objects in each set of tableware, and then sets up multiple assessment items, each of which sets a corresponding score. For example, the assessment item is set as the flavor dish is located directly above the dinner plate, the soup bowl is located on the left side of the flavor dish and in a straight line with the flavor dish, the chopstick holder is located on the right side of the dinner plate and is located at the upper third of the chopsticks, the toothpick is located between the long-handled spoon and the chopsticks, the red wine glass is located directly above the flavor dish, the white wine glass is located on the right side of the red wine glass, the water glass is located on the left side of the red wine glass, whether the table knife, fish knife, soup spoon, and appetizer knife are located on the right side of the decorative plate, whether the dessert fork and dessert spoon are located directly above the decorative plate, whether the table fork, fish fork, and appetizer fork are located on the left side of the decorative plate, whether the bread plate is located on the left side of the appetizer fork, whether the butter dish is located above the bread plate, etc. When the corresponding object in the tableware meets one of the above assessment items, the assessment score is accumulated by the score of the assessment item.
