The invention provides a trajectory detection method, a trajectory detection device, a storage medium and an electronic device. The method comprises the following steps: obtaining a plurality of movement tracks of a target object obtained through the detection of a first region through a plurality of monitoring devices, and enabling the detection regions of two adjacent monitoring devices in the plurality of monitoring devices to be at least partially overlapped; mapping the plurality of movement tracks into a regional planar graph of the first region to obtain a plurality of planar tracks; and splicing the plurality of plane tracks to obtain a first movement track of the target object in the first region. By means of the rat monitoring method and device, the problem that in the prior art,the rat monitoring efficiency is low due to the fact that the track of rats cannot be mastered through a rat and other pest monitoring method is solved. The effect of improving the rat monitoring efficiency is achieved.
