Embodiment Construction

[0016] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments, but the scope of protection of the present invention is not limited to the following examples, but should include all content in the claims.

[0017] A method for prompting surrounding environment information based on dual cameras, the steps of which are as follows:

[0018] Step (1) The camera will extract the front image, perform image compression, and then perform background difference and pattern matching on the image;

[0019] Binocular imaging can obtain two different images of the same scene. When the parameters of the two cameras (focal length f of the camera) are the same and the optical centers are placed parallel on a straight line, a parallel binocular stereo vision system is formed. By analyzing the geometry of each part The analysis of the relationship can obtain the distance information of the target object. figure 1 It is a typ...

Abstract

The invention provides a method for prompting ambient environment information by using two cameras, which is mainly characterized in that: (1) the environment is shot by using the two cameras keeping a certain distance, (2) acquired images are processed in a processor, the background difference algorithms, the pattern recognition algorithms and other algorithms are used to carry out background difference and pattern recognition, (3) the algorithms are optimized and can support the real-time background difference and pattern recognition, and (4) the ambient environment information is prompted according to the processing and identifying results by using a sensor, voice equipment and the like. The method achieves the purpose of helping the blind people and bringing great convenience to the outgoing of the blind people.

Description

technical field [0001] The present invention relates to the technical field of reminding road condition information of the surrounding environment, in particular to a method for prompting surrounding environment information based on dual cameras. Background technique [0002] At present, people have been devoting themselves to the development of care and protection for the disabled, but now the blind roads on many roads are often damaged due to various reasons, which brings inconvenience to the travel of the blind. For today's increasingly complex traffic and road conditions, the travel of the blind has become a very difficult problem. [0003] The present invention intends to use two cameras to acquire various information of the surrounding environment, and feed back to the user's surrounding environment information prompting device through voice vibration and the like. By optimizing the recognition and matching algorithm, this device can remind users of the surrounding ro...
