Method and device for software-based planning of a dimensional measurement

A non-transitory computer-readable medium comprising program code configured to carry out a method when the program code is executed on a computer, the method comprising:

• receiving an input command for selecting at least one measurement element of an object that is to be measured;
• determining a selection of measurable test features of the at least one selected measurement element, wherein each of the selection of measurable test features comprises a dimensionally measurable measurand of the at least one selected measurement element;
• determining a reduced subset of the selection of measurable test features depending on a view currently chosen on a display;
• and
• visualizing the test features contained in the reduced subset by using a graphical representation of each of the test features contained in the reduced subset on the display,
• wherein:
• determining the reduced subset of test features includes:
• determining which positions, spatial locations, or sizes the respective graphical representations of the test features contained in the selection would have in the view currently chosen on the display if the graphical representations were displayed on the display, and
• comparing the graphical representation of a test feature contained in the selection to at least one predefined criterion with regard to the position, the spatial location, or the size in the view currently chosen on the display,
• the test feature is assigned to the reduced subset only if the graphical representation of the test feature satisfies the at least one predefined criterion, and
• the at least one predefined criterion includes at least one of:
• (i) a direction of the graphical representation of the respective test feature, in the view currently chosen on the display, exceeding a predefined angle in relation to a normal direction, wherein the normal direction is orientated orthogonally to an image plane of the display, and
• (ii) the graphical representation of the respective test feature exceeding a predefined size in the view currently chosen on the display.

A device for software-based planning of a dimensional measurement of an object, comprising:

• a display;
• and
• a control unit connected to the display via a data connection, wherein:
• the control unit is configured to:
• receive an input command for selecting at least one measurement element of the object that is to be measured during the measurement;
• determine a selection of measurable test features of the at least one selected measurement element, wherein each of the selection of measurable test features comprises a dimensionally measurable measurand of the at least one selected measurement element;
• determine a reduced subset of the selection of measurable test features depending on a view currently chosen on the display;
• and
• visualize the test features contained in the reduced subset by generating a graphical representation of each of the test features contained in the reduced subset on the display,
• determining the reduced subset of test features includes:
• determining which positions, spatial locations, or sizes the respective graphical representations of the test features contained in the selection would have in the view currently chosen on the display if the graphical representations were displayed on the display, and
• comparing the graphical representation of a test feature contained in the selection to at least one predefined criterion with regard to the position, the spatial location, or the size in the view currently chosen on the display,
• the test feature is assigned to the reduced subset only if the graphical representation of the test feature satisfies the at least one predefined criterion, and
• the at least one predefined criterion includes at least one of:
• (i) a direction of the graphical representation of the respective test feature, in the view currently chosen on the display, exceeding a predefined angle in relation to a normal direction, wherein the normal direction is orientated orthogonally to an image plane of the display, and
• (ii) the graphical representation of the respective test feature exceeding a predefined size in the view currently chosen on the display.
