摘要：
A method, including acquiring a body cavity image andreceiving first and second sets of mapping points from a probeinserted into the cavity. A first registration, having a firstcumulative error value, is performed between the first set'smapping points and the image, each of the first set's mappingpoints having a respective first point error value, and a 3Danatomical map is generated including the first set's mappingpoints whose respective first point error values are less than aspecified threshold. A second registration is performed betweenthe received mapping points and the image, each of the receivedmapping points having a respective second point error value, thesecond registration having a second cumulative error value lowerthan the first cumulative error value, and an updated 3Danatomical map is generated including the received mappingpoints whose respective second point error values are less thanthe specified threshold.
