Embodiment Construction

[0056] The technical solutions of the present invention will be further described below with reference to the accompanying drawings.

[0057] The system design block diagram of the present invention is figure 1 As shown, the blind intelligent navigation glasses are mainly composed of three parts: hardware platform P1, ZerOMQ message transmission protocol P2, software platform P3. Among them, the hardware platform P1 is the core of the motherboard 1, and the ultrasonic sensor 2, the camera 3, the speech synthesis 4, the voice broadcast 5, and the warning reminder 6 are integrated based on the main board 1. The motherboard 1 is a central processor of the hardware platform, responsible for data collection, transmission, reception, and voice information; ultrasonic sensor 2 is responsible for collecting the distance information of the obstacle within 4m; 3 pixels of the camera can capture 3280 × 2464 Pixel static picture and video of 30fps 1080p, responsible for collecting scene video...

Abstract

The invention discloses a blind person intelligent navigation glasses system and device based on cloud computing, and the method comprises the steps: employing a camera to collect scene video information, employing an ultrasonic sensor to measure the distance of an obstacle, and transmitting the collected scene video information to a cloud; the uploaded video image information is analyzed through a target detection model and a distance measurement obstacle avoidance model which are deployed on the cloud, and target recognition, scene judgment, face recognition and distance measurement positioning tasks are completed; and finally, performing voice synthesis on the information analysis result and the obstacle distance information and broadcasting to the blind. The intelligent navigation glasses for the blind are smoother in operation, more convenient to use and higher in detection speed and precision.

Description

Technical field [0001] The present invention relates to the field of blind navigation technology, in particular, to a blind intelligent navigation glasses system and apparatus based on a cloud-based calculation. Background technique [0002] Because of the loss of vision, their lives will be greatly reduced, and most of their time will be in indoor activities. Considering that indoor living is an essential part of blind life, how to help blind people complete their lives, become a life of blind people Difficult to enhance the important content of blind life quality. In recent years, the study of indoor guideplate is gradually become a research direction of many scholars and institutions, and a large number of research results are emerging in the indoor guideplate. Summary is currently more popular in transfra blindness. The following: sensor guide, RF recognition guide, animal guide, etc. [0003] Sensor guide probes mainly use sensors such as ultrasonic, infrared rays to detect ...
