The edge extraction is carried out through the edge extraction operator, the position of the edge can be accurately determined, and noise can be effectively inhibited.
It should be noted that the morphological algorithm is a series of image processing operations based on shapes, and generates an output image by applying structural elements to an input image. Illustratively, the morphological algorithm may include dilation, erosion, closure and opening.
Through a morphological algorithm, discontinuous outline boundaries in the outline image corresponding to the tableware to be washed can be connected to obtain the outline shape image corresponding to the tableware to be washed. As shown in fig. 7, fig. 7 is a schematic view of an outline shape image.
Specifically, after the contour shape image corresponding to the tableware to be washed is obtained, the contour shape image corresponding to the tableware to be washed is compared with the standard contour image, and the type of the tableware corresponding to the tableware to be washed can be determined.
The standard outline image refers to the outline image corresponding to various tableware stored in the database of the dishwasher in advance. Such as the profile images of respective pairs of bowls, dishes, chopsticks, etc. As shown in fig. 8, fig. 8 is a schematic view of a standard outline image. Therefore, the contour shape image corresponding to the tableware to be washed can be compared with the standard contour image in the database, and if the similarity between the contour shape image and the standard contour image reaches the preset similarity, the type of the tableware corresponding to the tableware to be washed can be determined according to the type of the tableware corresponding to the standard contour image.
For example, if the similarity between the contour shape image corresponding to the dish to be washed and the standard contour image corresponding to the bowl is greater than the preset similarity, it may be determined that the dish type corresponding to the dish to be washed is "bowl".
In some embodiments, determining the type of dishes corresponding to the dishes to be washed in the target image may include: and determining the type of the tableware corresponding to the tableware to be washed in the target image according to the trained tableware recognition model.
It should be noted that the dish recognition model may include, but is not limited to, a Single shot multi box Detector (SSD) Network, a Convolutional Neural Network (CNN), a Restricted Boltzmann Machine (RBM), or a Recurrent Neural Network (RNN).
Specifically, sample images of a preset number corresponding to different types of tableware are configured, and types of the sample images are labeled; and inputting the sample image into the initial tableware recognition model for training until the predicted loss value of the trained tableware recognition model is less than or equal to the preset loss value, and finishing the training to obtain the trained tableware recognition model.

For example, the orientation may include an upper left corner, an upper right corner, a lower left corner, and a lower right corner with respect to the center of the housing of the dishwasher.
For example, if the arrangement shape of the dishes to be washed is a straight line shape, and the position coordinates of the dishes to be washed are located in the first quadrant and the second quadrant of the rectangular plane coordinate system, the positions of the dishes to be washed can be determined to be the upper left corner and the upper right corner. Therefore, the washing areas of the dishwasher are the upper left corner and the upper right corner, and the non-washing areas are the lower left corner and the lower right corner. As shown in fig. 9, fig. 9 is a schematic view of the arrangement shape of the line shape.
For example, if the arrangement shape of the dishes to be washed is "I" shape, and the position coordinates of the dishes to be washed are located in the second quadrant and the third quadrant of the rectangular plane coordinate system, the positions of the dishes to be washed can be determined as the upper left corner and the lower left corner. Therefore, the washing areas of the dishwasher are the upper left corner and the lower left corner, and the non-washing areas are the upper right corner and the lower right corner. As shown in fig. 10, fig. 10 is a schematic view of the arrangement shape of the "I" shape.
