Claim 0:
1. An electronic component evaluation method for causing a processor to execute a process, the electronic component evaluation method comprising executing on the processor the steps of:
Image-capturing an electronic component including a component body and a plurality of terminals attached tothe component body to obtain imaging data;
acquiring, with respect to at least one of the plurality of terminals, reference point information including at least one of position information and first height information of a plurality of reference points of the at least one of the plurality of terminals based on the imaging data; and
determining a state according to a shape of the electronic component based on a plurality of pieces of the reference point information,
wherein the determining of the state further includes:
creating a virtual plane based on the reference point information of at least three selected points of the plurality of reference points;
obtaining second height information based on other points of the plurality of reference points with respect tothe virtual plane as a reference plane, the other points and the at least three selected points being different;
determining whether the virtual plane is a valid plane or an invalid plane based on the second height information; and
detecting a flatness of the plurality of terminals based on the determined valid plane.
