Wide imaging surveys offer the opportunity to serendipitously discover and identify these traces of planetary formation and evolution. We present a method to acquire position, photometry, and proper motion measurements of Solar System objects in surveys using dithered image sequences. The application of this method on the Kilo-Degree Survey is demonstrated. Optical images of 346deg^2^ fields of the sky are searched in up to four filters using the AstrOmatic software suite to reduce the pixel to catalog data. The Solar System objects within the acquired sources are selected based on a set of criteria depending on their number of observation, motion, and size. The Virtual Observatory SkyBoT tool is used to identify known objects. We observed 20,221 SSO candidates, with an estimated false-positive content of less than 0.05%. Of these SSO candidates, 53.4% are identified by SkyBoT. KiDS can detect previously unknown SSOs because of its depth and coverage at high ecliptic latitude, including parts of the Southern Hemisphere. Thus we expect the large fraction of the 46.6% of unidentified objects to be truly new SSOs. Our method is applicable to a variety of dithered surveys such as DES, LSST, and Euclid. It offers a quick and easy-to-implement search for Solar System objects. SkyBoT can then be used to estimate the completeness of the recovered sample.2018A&A...610A..21Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/610/A21CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/610/A21https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/610/A21http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/610/A21https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/610/A21https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/610/A21http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/610/A21GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/610/A21/large (20221 SSOs with false- positive content below 0.05%)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/610/A21/large?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/610/A21/large?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/610/A21/large?GETtext/xml+votable180.050000true359.548505-32.789111940.005555555555555556Cone search capability for table J/A+A/610/A21/small (8069 SSOs with false-positive content of about 24%)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/610/A21/small?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/610/A21/small?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/610/A21/small?GETtext/xml+votable180.050000true359.762525-31.445678890.0055555555555555564/1365 1621 1642 1685 1706 2932 5/1024-1026 2048 2050 4109-4110 4128-4130 4132 4138 5459 5468-5469 6397-6399 6477 6479 6481 6483 6488 6490-6492 6501 6503 6512-6513 6561-6564 6566 6572-6574 6737-6739 6744-6745 6748-6750 6819 6828 6830 6912-6914 7834 8831 8907 8967 8971 8974-8975 8984 8993-8995 8997 10239 11262 11639 11643 11645-11646 11719 11725-11727 11732-11734 11736-11738 11746-11747 6/4108 4112 4128 8198 8204 8224 16413 16431 16435 16444-16446 16456 16524-16526 16532 16536 16545 16547-16548 16556 21829-21831 21833 21835 21861 21863 21881 21884 25567 25583 25587 25907 25914-25915 25923 25928-25929 25931 25956-25957 25959 25972-25973 25975-25978 26000-26001 26021-26023 26028-26029 26032 26034 26056-26058 26060 26064 26159 26189 26191 26202 26213 26224-26226 26243 26260 26262 26268 26270 26300 26336 26911 26942-26943 26947 27004 27028-27029 27031 27034-27035 27045-27047 27049-27054 27056-27058 27072 27074 27088 27221-27223 27229 27247 27256 27258-27259 27270-27271 27273-27275 27290-27291 27316 27318-27319 27324 27392-27394 27660 27664 27680 31294 31330 31373 31375 31377 31379-31382 31386 31393 31395 31397-31399 31401-31402 31408 31410 31424-31425 34539 34542-34543 35287 35293 35295 35313 35315-35317 35321 35323 35668 35863 35879 35891 35893-35895 35905-35906 35908-35909 35911-35912 35914 35917-35919 35922 35928 35930 35940-35942 35944-35945 35970 35984 35986-35987 35992 35994 36000 36002 36008 40949 40951 40954-40955 45039 45043 45046 45052 45054-45055 46551 46555 46567 46577-46579 46588-46589 46591 46871 46875 46893-46895 46897 46899 46956-46957 46962 46979-46982 46992-46993 46996-46997 47008-47009 47011-47012 47040 47042https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/610/A21?format=asciidefaultJ/A+A/610/A21/large20221 SSOs with false- positive content below 0.05%recnoRecord number assigned by the VizieR team.
