The invention provides a quick switching method for a multiple tracking videos. A tracked object (2) operates in a riverway (1). M image cameras are uniformly arranged above the riverway (1). P image cameras (2) in the m image cameras (3) synchronously transmit the photographed signal of the tracked object (2) to p channels of a personal computer PC (4). When the tracked object (2) operates to the part right below an n-th image camera (3), a signal which is transmitted from an (n-1)th image camera to the PC (4) is deleted, and a signal of an (n+p-1)th image camera (1) is transmitted to the channel of the PC (4), wherein the channel of the PC (4) corresponds with the deleted signal of the (n-1)th image camera. Through the quick switching method for the multiple tracking videos, the switching time for the videos can be greatly reduced. Shortening of the switching time can reduce the superposing range of two videos, namely the tracked object in the video can be effectively captured. Furthermore a requirement for the speed of the tracked object is expanded.
