Aiming at the problem that the existing guide cane and guide dog have limited effect in practical work

poor usage effect

high cost and low popularity

an intelligent guide blind system based on RGB-D depth camera is developed.The blind system realizes the detection of obstacles through RGB-D depth camera

combines A

algorithm to realize local obstacle avoidance

realizes global path planning through GPS remote navigation

calculates the processing signal through the upper personal computer（PC）

and controls the vibration array and emits voice through the lower PC system.The signal prompts the blind.The system shows accurate positioning effect and good obstacle avoidance ability in actual test.The voice prompt and vibration prompt are timely and accurate.The o

bstacle distance detection error based on RGB-D depth camera is less than 3%

which basically meets the needs of system design.
