The invention discloses a target detection method, device and equipment and a storage medium, and belongs to the field of image recognition. According to the technical scheme provided by the embodiment of the invention, in a game testing process, a detection terminal can preliminarily screen an area where a target object is located through the template image of the target object, furthermore, thewrong area obtained in the matching process is eliminated through image feature difference information, and finally a first candidate sub-image meeting a target condition can be obtained, and is an area containing the target object; and the detection terminal can highlight the first candidate sub-image, detection personnel can visually see the position of the target object in the to-be-detected image, the game test process is automatically completed by the detection terminal, and the detection personnel do not need to perform detection on terminals of different models one by one, so that the game test efficiency is improved.
