Embodiment 1

[0045] Embodiment 1 A road recognition device based on a laser direction sensor and an artificial intelligence platform.

[0046] Such as figure 1 As shown, the laser direction sensor and the cloud platform artificial intelligence road recognition device of the embodiment of the present invention include a laser direction sensor, a head-mounted dual-axis anti-shake camera, and a binaural positioning direction sensor headband.

[0047] The laser direction sensor includes 7 laser diodes, one of which indicates the laser diode in the forward direction, three laser diodes in the right direction, and three laser diodes in the left direction; it is used to produce 47 The temperature below 100 degrees Celsius; the right and left pointing laser diodes illuminate the dorsal ear groove from far to near according to the distance from the forward pointing laser diode. Turn around or move forward; the laser direction sensor is connected to the artificial intelligence device of the head-mo...

Embodiment 2

[0057] Embodiment 2 A head-mounted dual-axis anti-shake directional camera.

[0058] Such as figure 2 As shown, the head-mounted internal and external dual-axis anti-shake directional camera of the embodiment of the present invention includes a right pan-tilt motor, a lower pan-tilt motor, a waterproof casing, a camera, an artificial intelligence device, and a network communication unit.

[0059] The right gimbal motor unit is outside the fuselage, responsible for up and down anti-shake and orientation.

[0060] The lower gimbal motor unit is inside the fuselage, responsible for left and right anti-shake.

[0061] The camera includes a monocular camera module for human motion estimation.

[0062] The artificial intelligence device includes a positioning unit, a human body motion estimation unit, a terrain pre-shooting storage unit, and a road obstacle analysis unit; the human motion estimation unit is used to locate the key points of the real-time video at the human joints ...

Embodiment 3

[0063] Embodiment 3 The usage method of the laser direction sensor.

[0064] Such as Figure 3a As shown, the laser direction sensor in the embodiment of the present invention includes 7 laser diodes, one of which indicates the laser diode in the forward direction, three laser diodes in the right direction and three laser diodes in the left direction; Temperatures below 47 degrees are generated at different positions on the body; the right and left pointing laser diodes illuminate the dorsal canal from far to near according to the distance from the forward pointing laser diodes, and the positive pointing laser diodes illuminate the highest point of the back of the ears , so as to instruct the blind person to turn left and right or to move forward; the laser direction sensor is connected to the artificial intelligence device of the head-mounted dual-axis anti-shake camera through the circuit of the hoop body, and is controlled by the artificial intelligence device; three laser ...

Abstract

Laser direction sensor and artificial intelligence cloud platform road recognition device, including laser direction sensor, head-mounted dual-axis anti-shake camera, binaural positioning direction sensor headband. The laser direction sensor is used to irradiate different positions on the back of the ear of the user to generate a temperature below 47 degrees; pointing the laser diode to the right and left according to the distance from the forward direction to the laser diode, and irradiating the back of the ear from far to near. The forward direction indicator laser diode is irradiated on the highest point of the dorsal groove, thereby instructing the blind person to turn left and right or move forward. The head-mounted internal and external dual-axis anti-shake directional camera is used for real-time and accurate recognition of human body posture in the video, to judge whether there is or is about to enter the blind road 5 meters ahead, and to evaluate whether there are obstacles added to the blind road 5 meters ahead. The binaural positioning direction sensing headband includes a direction sensor for sensing the direction of the headband; the positive direction of the direction sensor is directly in front of the user's face.

Description

technical field [0001] The invention relates to the technical fields of cooperative interoperation of traffic systems, automatic driving, big data, artificial intelligence, smart city and blind road, and specifically relates to a road recognition device and method based on a laser direction sensor and an artificial intelligence cloud platform. Background technique [0002] There are about 5 million blind people in China, accounting for 18% of the total number of blind people in the world, accounting for about 3.8‰ of the national population, with an average of 3,800 blind people per million people. About 450,000 new blind people are added every year. By 2020, the total number of blind people is expected to reach 20 million. my country is the country with the largest number of blind people in the world. The transportation of blind people is a livelihood issue that cannot be ignored, and has always been highly concerned by the government. [0003] Blind paths are road facilit...
