摘要： An oral treatment device includes a head for use in treating an oral cavity of a user, an inertial measurement unit, IMU, configured to generate signals dependent on position and/or movement of the head relative to the oral cavity, and intraoral image sensor equipment configured to generate image data representing at least a portion of the oral cavity. The oral treatment device includes a controller configured to process the generated signals and the generated image data using a trained classification algorithm to determine an intraoral location of the head of the oral treatment device. The controller is configured to control the oral treatment device to perform an action based on the determined intraoral location.

摘要： An oral treatment device includes image sensor equipment configured to generate image data indicative of a sequence of images representing at least a portion of an oral cavity of a user. The oral treatment device includes a controller configured to process the image data to determine a movement parameter indicative of movement of the oral treatment device relative to an interproximal gap between adjacent teeth in the oral cavity of the user. The controller is configured to control the oral treatment device to perform an action based on the determined movement parameter.

摘要： An oral treatment device includes a head for use in treating an oral cavity of a user, the oral cavity including a plurality of oral cavity zones, and an inertial measurement unit, IMU, operable to output signals dependent on position and/or movement of the head. The oral treatment device includes a controller configured to receive signals from the IMU indicating position and/or movement of the head relative to the oral cavity, and process the received signals using a trained non-linear classification algorithm to obtain classification data. The classification algorithm is trained to identify, from the plurality of oral cavity zones, an oral cavity zone in which the head of the oral treatment device is located. The controller is configured to control the oral treatment device to perform an action using the obtained classification data.

摘要： An oral treatment device includes intraoral image sensor equipment configured to generate image data representing at least a portion of the oral cavity of a user during use by the user of the oral treatment device. The oral treatment device includes a controller configured to process the generated image data to determine location data indicating a location of an interproximal gap between adjacent teeth in the oral cavity of the user. The controller is configured to process the generated image data using a trained classification algorithm configured to identify interproximal gaps, the trained classification algorithm having been trained prior to the use of the oral treatment device. The controller is configured to, during the use of the oral treatment device, control the oral treatment device to deliver a treatment to the detected interproximal gap based on the location data.
