Abstract: This paper presents a new method of automatic detection on target from image captured by outdoor firing training system with complex background.All the images are picked up by a camera on pikestaff.Boosting learning algorithm is used here to extra the features of target from the images of target.And then train the training samples to gain a strong classifier，which can help to detect the location of target more accurately.We try to apply the method to a relevant example，and the result of the trial indicates the validity of the method.
