Operating assistance method, control unit, operating assistance system and working device

An operating assistance method for a working device, comprising the following steps:

• (S1) obtaining, at consecutive times, object boxes for an object in a field of view of the working device, or data characterizing the object boxes;
• (S2) from the object boxes of the object for images recorded in succession or direct succession, determining:
• (i) an instantaneous change of scaling of an object box for the object, or variables derived from the instantaneous change of scaling the object box for the object, and (ii) an instantaneous lateral change of position of the object box for the object;
• (S3) determining a predicted object box, predicted in for the future, from the instantaneous change of scaling of the object box for the object or the variables derived from the instantaneous change of scaling of the object box for the object, and from the instantaneous lateral change in position of the object box for the object;
• (S4) determining and evaluating:
• (i) a position of the predicted object box and/or (ii) a ratio of a lateral extension of the predicted object box to a lateral extension of:
• (a) a covered field of view, and/or (b) the recorded images or a section of the recorded images;
• and
• (S5) as a function of the result of the evaluation, determining:
• (i) whether or not the object which forms the basis of the predicted object box, is critical with regard to a possible collision, and/or (ii) an operating state of the working device being controlled or regulated.

A control unit for an operating assistance system of a working device, configured to:

• (S1) obtain, at consecutive times, object boxes for an object in a field of view of the working device, or data characterizing the object boxes;
• (S2) from the object boxes of the object for images recorded in succession or direct succession, determine:
• (i) an instantaneous change of scaling of an object box for the object, or variables derived from the instantaneous change of scaling the object box for the object, and (ii) an instantaneous lateral change of position of the object box for the object;
• (S3) determine a predicted object box, predicted in for the future, from the instantaneous change of scaling of the object box for the object or the variables derived from the instantaneous change of scaling of the object box for the object, and from the instantaneous lateral change in position of the object box for the object;
• (S4) determine and evaluate:
• (i) a position of the predicted object box and/or (ii) a ratio of a lateral extension of the predicted object box to a lateral extension of:

• and
• (S5) as a function of the result of the evaluation, determine:
• (i) whether or not the object which forms the basis of the predicted object box, is critical with regard to a possible collision, and/or (ii) an operating state of the working device being controlled or regulated.
