Image detection and identification method and device

The invention relates to an image detection and recognition method and device, and the method comprises the steps: carrying out the frame extraction of video stream data, and obtaining all frames of images; performing target detection on each frame of image, and combining the images with similar targets according to a target detection result to obtain a same-target data set; and performing target identification on the first image in the same target data set, and taking the identification result of the first image as the identification result of other frames of images. According to the method, after each frame of image in video stream data is extracted, target detection is carried out on each frame of image, and then images with similar targets are merged into a data set as a same-target data set. According to the target identification method, when target identification is carried out on each frame of image, only one frame of image in the same target data set needs to be subjected to target identification, and
