The invention discloses a target image quick retrieval method and system based on artificial intelligence. The method comprises the following steps of acquiring a template image and a plurality of known tags corresponding to the template image; extracting a to-be-detected image from the target image database; inputting the to-be-detected image and the template image into a trained convolutional neural network, and outputting a hash code of the to-be-detected image and a hash code of the template image; based on the Hamming distance between the Hash code of the to-be-detected image and the Hash code of the template image, obtaining the similarity between the to-be-detected image and the template image, and selecting one or more to-be-detected images with the similarity higher than a set threshold value as the retrieval results to be output. By using an artificial intelligence technology, based on the convolutional neural network, image features are extracted from image samples, collected by a robot vision platform, in a complex scene by using a Hash method, by introducing the distinguishing easy-to-confusion entities, a similarity relationship can be optimized, the sample attention is distinguished, and article retrieval in the complex scene can be better coped with.

The invention discloses a robot movement mechanism used for robot visual technology teaching, and relates to the field of robots. Connecting posts are fixedly connected to four corners of the upper surface of a support table, a connecting frame is fixedly connected to the end parts of the connecting posts, a first movement mechanism is connected in a framework of the connecting frame, the mobile end of the first movement mechanism is connected with the fixed end of a second movement mechanism, the mobile end of the second movement mechanism is connected with the fixed end of a third movement mechanism, the mobile end of the third movement mechanism is fixedly connected with a fixed body, the fixed body is rotatably connected with a rotation body though a rotation mechanism inside the fixedbody, the rotation body is hinged to a mounting body through a driving mechanism arranged inside the rotation body, and a camera is detachably connected to the bottom of the mounting body; the movement directions of the first movement mechanism, the second movement mechanism and the third movement mechanism are vertical in pairs; and the support table is rotatably connected with an observation table through a rotation device. The robot movement mechanism is high in degree of freedom, and information can be well collected.
