Embodiment 1

[0078] Embodiment 1, Universal Object Recognition:

[0079] Figure 1~3 The shown a kind of intelligent speech guiding system based on AI open platform includes interactive box 1 and control and voice output box 2; the upper end of interactive box 1 is equipped with camera 3, and the side is provided with a plurality of interactive box USB interfaces 4, wherein A microphone assembly is connected to an interactive box USB interface through a USB plug 5;

[0080] The interior of the interactive box 1 is provided with a raspberry pie main control board; the raspberry pie main control board is equipped with onboard bluetooth and onboard WIFI, and the raspberry pie main control board is electrically connected with the camera and the USB interface of the interactive box; The camera is connected to Raspberry CSICamera interface.

[0081] The box body of the interactive box is provided with a power indicator light 14 . According to the actual application, a battery is installed ins...

Embodiment 2

[0095] Embodiment 2. Customized object recognition:

[0096] The difference between this embodiment and Embodiment 1 is that the usage method of this embodiment can customize and customize recognition targets, such as various information signs such as bus stops and signs, and return results when specified objects appear in the image. The function is realized by using Baidu EasyDL customized training and service platform. Users customize the training model according to their own needs. The recognition object is determined by the user. After the model training is completed, apply for release. After the release is successful, it can be called. The program passes the image to be recognized and the model Match and compare to get the recognition result. The calling steps are similar to the general object recognition steps, the difference is that the address of the calling interface is different. If the specified object is recognized in the image, the recognition accuracy and the po...

Embodiment 3

[0101] Embodiment three, identification of traffic lights:

[0102] This embodiment first judges whether there is a traffic light in the image through customized image recognition. If the recognition judgment result is that a traffic light is found in front, then the traffic light is cut out according to the position coordinates of the traffic light in the image in the data return result, saved separately, and then judged by Opencv Whether it is a red light or a green light, it guides the blind to pass. Such as Figure 10 As shown, the difference from Embodiment 1 is as follows:

[0103] a. Recognition command; the microphone receives the voice command, and preprocesses the voice command through the main control board of the Raspberry Pi. Text, and match with the command model, if the match is successful, the command is determined to be valid;

[0104] b. Judging that the instruction type is a traffic light identification instruction;

[0105] c. Analysis and processing in...

Abstract

The invention discloses an intelligent voice blind guiding system based on an artificial intelligence (AI) open platform. The intelligent voice blind guiding system based on the AI open platform comprises an interaction box and a control and voice output box, wherein a camera is arranged at the upper end of the interaction box; multiple interaction box universal serial bus (USB) interfaces are arranged on the side surface of the interaction box; a microphone component is connected onto one interaction box USB interface through a USB plug; an ultrasonic wave sensor is arranged at one end of thecontrol and voice output box; and an output box USB interface, an earphone connector and a battery interface are arranged at the other end of the control and voice output box. An application method comprises the steps of recognizing commands; analyzing and processing different kinds of commands; and synthesizing the commands to generate voice, and playing through a loudspeaker or an earphone. According to the intelligent voice blind guiding system based on the AI open platform provided by the invention, the universality and the practicability of the blind guiding system are improved, multipleenvironments and objects can be recognized, the blind guiding system can be applied to more places, a blind guiding mechanism is perfected, and a blind guiding effect is improved. The intelligent voice blind guiding system based on the AI open platform is small in volume, light in weight and high in integration; the interaction box and the control and voice output box can be wore flexibly; and the intelligent voice blind guiding system based on the AI open platform can be carried by adopting an arm bag form and is powered by an internal battery or an external power bank.

Description

technical field [0001] The present invention relates to a blind-guiding system and a usage method, in particular to an intelligent voice blind-guiding system and a usage method based on an AI open platform. Background technique [0002] According to data from the China Disabled Persons' Federation, China currently has at least 17.31 million blind people, making it the country with the largest number of blind people in the world. In daily life, 95% of people's information is obtained by vision. Due to the congenital physical defects of blind people, they cannot find obstacles accurately and timely. Therefore, how to walk safely is the biggest problem in the life of blind people. They may travel with the aid of guide dogs, guide sticks, and the help of others. Guide dogs can lead pedestrians, but unfortunately, there are some places where guide dogs are not allowed to enter. If you don't use a guide dog, you can also use a guide stick to grope forward very carefully, but the...
