Target detection method and device and computer storage medium

The invention discloses a target detection method and device and a computer storage medium. The target detection method comprises the steps of obtaining a to-be-detected image; obtaining a first target detection frame of the to-be-detected image through a target detection network; acquiring a second target detection frame of the to-be-detected image through a motion detection network; acquiring a foreground image of the to-be-detected image according to the first target detection frame and the second target detection frame; and inputting the foreground image into a target classification network, and outputting a target classification result of the to-be-detected image. Through the above mode, the foreground target is effectively extracted from the background, and compared with traditional target detection, the target detection method of the application can detect the target with smaller target pixel and lower picture contrast. 本申请公开了一种目标检测方法、装置以及计算机存储介质，该目标检测方法包括：获取待检测图像；通过目标检测网络获取所述待检测图像的第一目标检测框；通过运动检测网络获取所述
