The invention provides an indoor parking area vehicle locating and searching method based on a nearest neighbor. The method comprises the following steps: building a locating system of an LANDMARC framework; performing one-time scan round by using all readers; when a certain to-be-located label is detected by three readers, recording a binary string matrix corresponding to each reader and reading the condition of a reference label so as to select the nearest neighbor; calculating the position coordinates of the to-be-located label by using the coordinates of the nearest neighbor. According to the method disclosed by the invention, the hardware cost for building the locating system is greatly lowered; the method is adaptive to dynamic uncertainty caused by changes of wall bodies, object shielding, ineffectiveness of the readers and the like in an indoor environment; when the quantity of the readers is high, the calculation amount can be effectively reduced, and the location accuracy can be improved.
