Technical Field

The invention belongs to the technical field of image acquisition, and particularly relates to an automatic lifting platform for a camera.

Background

The pattern stimulus acts on the sense organ and one recognizes it as an experienced process of a certain pattern, also called image recognition. In image recognition, there is not only information that enters the sense at that time, but also information stored in memory. Only through the stored information and the current information to compare the processing process, the image recognition can be realized, and the image recognition is an important field of artificial intelligence. In order to create a computer program that simulates human image recognition activities, different image recognition models have been proposed. Such as a template matching model. This model considers that a certain image is recognized and that it is necessary to have a memory pattern, also called template, of this image in past experience. If the current stimulus matches the template in the brain, the image is identified. For example, if there is an a-template in the brain, the letter a is recognized if its size, orientation, shape are identical to the a-template. The model is simple and clear and can be easily applied to practical use. However, this model emphasizes that the image must be completely matched with the template in the brain for recognition, and in fact, a person can recognize not only an image that is completely matched with the template in the brain, but also an image that is not completely matched with the template. For example, one can recognize not only a specific letter a, but also various letters a of a print, a script, an incorrect direction, and different sizes. At the same time, the number of images that a person can recognize is large, multi-angular, and it is not possible if each image recognized has a corresponding template in the brain.

The existing identification process of the model requires multi-angle framing, and when framing and replacing the model at different angles, the distance between a camera and an article needs to be manually adjusted to ensure more accurate identification of the article, but the mode increases the working strength of workers and increases the time for image acquisition.
