This paper presents extensive BVRIYJHKs-band light curves of SN2017cbv, covering the phase from -16 to +125days relative to B-band maximum light. The SN2017cbv reached a B-band maximum of 11.710{+/-}0.006mag, with a postmaximum magnitude decline of {Delta}m15(B)=0.990{+/-}0.013mag. The SN suffered no host reddening based on Phillips intrinsic color, the Lira-Phillips relation, and the CMAGIC diagram. By employing the CMAGIC distance modulus {mu}=30.58{+/-}0.05mag and assuming H0=72km/s/Mpc, we found that 0.73M{sun} 56Ni was synthesized during the explosion of SN2017cbv, which is consistent with estimates using reddening- and distance-free methods via the phases of the secondary maximum of the near-IR- (NIR-) band light curves. We also present 14 NIR spectra from -18 to +49 days relative to the B-band maximum light, providing constraints on the amount of swept-up hydrogen from the companion star in the context of the single degenerate progenitor scenario. No Pa{beta} emission feature was detected from our postmaximum NIR spectra, placing a hydrogen mass upper limit of 0.1M{sun}. The overall optical/NIR photometric and NIR spectral evolution of SN2017cbv is similar to that of a normal SN Ia, even though its early evolution is marked by a flux excess not seen in most other well-observed normal SNe Ia. We also compare the exquisite light curves of SN2017cbv with some Mch delayed detonation models and sub-Mch double detonation models.2020ApJ...904...14Whttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/904/14CatalogResearchIsServedByTAP VizieR generic servicerelated-toII/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)VII/233 : The 2MASS Extended sources (IPAC/UMass, 2003-2006)J/AJ/130/873 : Properties of BQS objects in the SDSS DR3 area (Jester+, 2005)J/ApJ/659/122 : Improved distances to type Ia supernovae (Jha+, 2007)J/ApJ/689/377 : SNe Ia NIR standard candles from PAIRITEL (Wood-Vasey+, 2008)J/AJ/137/4186 : UBVRI standards around celestial equator (Landolt, 2009)J/ApJ/699/L139 : Spectral parameters of SNe Ia (Wang+, 2009)J/ApJ/721/1608 : Absolute UV magnitudes of type Ia SNe (Brown+, 2010)J/AJ/139/519 : Carnegie supernova project.
