The invention provides a continuous identification device for panchromatic billiards and bi-color billiards. The continuous identification device for the panchromatic billiards and the bi-color billiards comprises a billiard raceway, a color identification device, a billiard stopping and releasing device and a central control system, wherein the billiard raceway is integrally of a U-type groove structure; the color identification device comprises a plurality of color sensors which are arranged above and on the two sides of the billiard raceway respectively; the billiard stopping and releasing device comprises a front stopping piece, a rear stopping piece, a connection rod and a steering engine; the central control system is respectively connected with the color sensors. Meanwhile, the invention discloses an identification method of the identification device. By means of the continuous identification device and method for the panchromatic billiards and the bi-color billiards, the billiards are not additionally changed, the application range is wide, the color sensors are adopted to comprehensively collect the color data of the billiards in different directions of the billiards on the four detection points of two billiard positions and distinguish the panchromatic billiards and the bi-color billiards through comprehensive analysis and judgment, the reliability is high, the billiard stopping and releasing device can accurately control the billiards to sequentially enter the detection billiard position to be detected one by one, the stopping and releasing time is accurate and controllable, the universality is good, and the device and method are completely applicable to further design and development of automatic billiard machines.
