As a further technical scheme of the invention: when the obstacle is a flowerpot, the obstacle avoidance process is as follows: step 1, when the blind person is close to the flowerpot and the distance is 1m-0.2m, the earphone sends out the sound effect with medium frequency and low intensity to the blind person in the range of 90 degrees with the flowerpot as the midpoint; step 2, the blind persons hear the alarm signals and avoid the obstacle in time, and then the alarm signals disappear; and 3, if the blind person continues to approach the flowerpot until the distance of the blind person to the flowerpot is 0.2m or less, the earphone can send out the sound effect with medium frequency and high intensity to the blind person in the range of 90 degrees taking the flowerpot as the midpoint.
As a further technical scheme of the invention: when the obstacle is a large stone pier, the obstacle avoidance process is as follows: step 1, when the blind person is close to a big stone pier and the distance is 0.5m-0.2m, the earphone sends out high-frequency low-intensity sound effects to the blind person in a range of 45 degrees with the big stone pier as a midpoint; and 2, the blind person hears the alarm signal and avoids the obstacle in time, so that the alarm signal disappears. And 3, if the blind person continues to approach the stone pier until the stone pier is within 0.2m, the earphone can send high-frequency and high-strength sound effects to the blind person in a range of 45 degrees with the stone pier as the middle point.
As a further technical scheme of the invention: when the obstacle is a parking area, the obstacle avoidance process is as follows: step 1, sounding a voice broadcast when the distance from the parking area is 1m, then sounding the sound effect of low frequency and high strength when the earphone is 90 degrees away from the parking area, and guiding the blind person to walk along the semicircular area; and 2, guiding the sound effect to disappear until the blind person reaches the end point of the semicircular area. And 3, if the distance between the blind person and the obstacle area is smaller than 0.2m, the earphone sends out a medium-frequency high-intensity alarm sound effect to the blind person.
Compared with the prior art, the invention has the beneficial effects that:
the HRTF earphone has the effect of 360-degree stereo surrounding, and the blind person can be helped to recognize the position of the obstacle in the brain through the position of the sound. And a guided obstacle avoidance scheme is provided on the traditional obstacle avoidance means, and whether an alarm signal or a guide signal is distinguished through the difference of sound effect frequencies. The distance of the blind person's movable range, namely the size of the unobstructed space, is distinguished by the sounds with different intensities, and effective obstacle information can be provided for the blind person by adding voice prompts.

Detailed Description
The following description of the technical solutions in the embodiments of the present invention will be clear and complete, and it is obvious that the described embodiments are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
As shown in FIG. 1, an HRTF earphone system with intelligent obstacle avoidance reminding function comprises a walking stick with a multi-angle sensor and an HRTF earphone, wherein static obstacles detected by the multi-angle sensor are fed back to the HRTF earphone after being processed, and after receiving the information of the walking stick, the HRTF earphone is transmitted to a blind person in 360-degree azimuth different sound modes, so that the blind person can feel intuitively.
The following is a detailed description of examples:
example 1, as shown in fig. 2, the obstacle avoidance method in the case of a flowerpot: on the premise that the blind walks around the square, the blind can touch the static obstacle flowerpot in the way. Step 1, when the blind person is close to the flowerpot and the distance is 1m-0.2m, the earphone sends out the sound effect with medium frequency and low intensity to the blind person in the range of 90 degrees with the flowerpot as the midpoint. And 2, the blind person hears the alarm signal and avoids the obstacle in time, so that the alarm signal disappears. And 3, if the blind person continues to approach the flowerpot until the distance of the blind person to the flowerpot is 0.2m or less, the earphone can send out the sound effect with medium frequency and high intensity to the blind person in the range of 90 degrees taking the flowerpot as the midpoint.
Example 2, as shown in fig. 3, the obstacle avoidance method in the case of a large stone pier: on the premise that the blind walks around the square, the blind can touch the static obstacle stone pier in the way. And 1, when the blind person is close to the big stone pier and the distance is 0.5m-0.2m, the earphone sends out high-frequency low-intensity sound effects to the blind person in a range of 45 degrees with the big stone pier as the midpoint. And 2, the blind person hears the alarm signal and avoids the obstacle in time, so that the alarm signal disappears. And 3, if the blind person continues to approach the stone pier until the stone pier is within 0.2m, the earphone can send high-frequency and high-strength sound effects to the blind person in a range of 45 degrees with the stone pier as the middle point.
Example 3, as shown in fig. 4, as shown in fig. 2, starts from a triangle in the figure. Step 1, sounding a voice broadcast when the distance from the parking area is 1m, then sounding the sound effect of low frequency and high strength when the earphone is 90 degrees away from the parking area, and guiding the blind person to walk along the semicircular area. And 2, guiding the sound effect to disappear until the blind person reaches the end point of the semicircular area (namely, the pentagonal star point). And 3, if the distance between the blind person and the obstacle area is smaller than 0.2m, the earphone sends out a medium-frequency high-intensity alarm sound effect to the blind person.
