Image-based method for simplifying a vehicle-external takeover of control of a motor vehicle, assistance device, and motor vehicle

A method for simplifying a takeover of control of a motor vehicle by a vehicle-external operator, the method comprising:

• in a conditionally automated operation of the motor vehicle, acquiring and semantically segmenting images of an environment of the motor vehicle by way of a predetermined trained segmentation model,
• based on at least one of the images in each case, predicting errors of the segmentation model,
• for an error prediction, which, according to a predetermined criterion, triggers an automatic output of a request for the takeover of control by the vehicle-external operator, automatically generating an image-based visualization that includes an image and visual highligting of an area of the image corresponding to the error prediction, wherein the visual highlighting is superimposed on the image, and
• sending the request and the visualization to the vehicle-external operator, wherein:
• the errors of the segmentation model are predicted pixel by pixel, an average error is determined based on the errors of the segmentation model for the respective image, and it is checked as at least a part of the predetermined criterion whether the average error is greater than a first predetermined error threshold value.
