A certain pointing information or image-text information identification device

Abstract

The invention discloses a certain pointing information or image-text information identification device. The system comprises a photographing module and a monitoring module. the photographing module comprises a camera; when the monitoring module is triggered; the pointing information or image-text information identification equipment shoots downwards through the camera to obtain a book image to shoot and identify the book; the monitoring module comprises an infrared or ultrasonic monitoring unit; the infrared or ultrasonic monitoring unit is an infrared or ultrasonic transmitting and receivinggroup; wherein triggering of the monitoring module comprises triggering by transmitting and receiving reflected infrared rays or ultrasonic waves through the infrared or ultrasonic monitoring unit, the infrared or ultrasonic monitoring unit comprises a first type of infrared or ultrasonic monitoring unit, and the first type of infrared or ultrasonic monitoring unit causes the first type of triggering. Implementation of the embodiment of the invention is favorable for identifying the pointing point of a hand on a book or identifying which book or page.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to image-text recognition. Background technique [0002] At present, there is no actual product that relies on the camera to realize point reading and pointing graphic recognition, especially there is no actual product that can directly use fingers to point on the book and can take a photo to identify which page and position the pointing is on, and there is no direct finger pointing on the graphic text. The actual product that can take pictures and recognize the pictures and texts of the pointing points, [0003] Some of the current schemes cannot be converted into practical products. These schemes rely entirely on image recognition of continuous photographs. The disadvantage is that, on the one hand, the accuracy of photographic recognition in complex book backgrounds is low, and it is different from other simple backgrounds. Books have different patterns, and some patterns ar...

Problems solved by technology

[0003] Some of the current schemes cannot be converted into practical products. These schemes rely entirely on image recognition of continuous photographs. The disadvantage is that, on the one hand, the accuracy of photographic recognition in complex book backgrounds is low, and it is different from other simple backgrounds. Books have different patterns, and some patterns are similar to fingers or sticks and are easy to confuse. They are completely recognized only by taking photos. In practical applications, they are often misidentified as pointers when there is no pointing, or it takes a long time to be reliable in practical applications. Confirm whether there are pointers. On the other hand, most of the time, the user does not operate anything, neither turning pages nor pointing. At this time, the continuous photo recognition is invalid and inefficient, and it will also occupy the processor memory of the device and cause other problems. The work cannot be completed well. If you want to take continuous invalid photos and complete other tasks at the same time, the hardware requirements are too high, the system is too complicated and the cost is too high, and it is impossible to form a practical product.

[0004] Therefore, there is currently no photo recognition of the actual product that is directly pointed on the book with your finger
