Embodiment Construction

[0039] The following is a detailed description of the embodiments of the present invention. This embodiment is carried out based on the technical solution of the present invention, and provides detailed implementation methods and specific operation processes.

[0040] Such as figure 1 It is a schematic diagram of the sensor's work. The fan-shaped area is the sensing area of ​​the sensor. After the target enters the sensing area, the sensor can test the distance from the target to the sensor. At the same time, the sensor divides the sensing area into multiple small areas. Through the signal processing method, the azimuth of the target object from the sensor can be obtained, and the sensor can judge the size of the target object by how many areas the target object appears in.

[0041] Such as figure 2 It is a structural diagram of the system of the present invention, including a processor, a signal splitter, a multi-channel transmitter, a transmitting signal processing module,...

Abstract

The invention provides a sensor obstacle avoiding system and method capable of detecting orientation of an obstacle. The system comprises a processor, a signal splitter, a multiple-path emitter, an emission signal processing module, a reception signal processing module and a receiver. The processor comprises a TOF chip. The emission signal processing module is arranged in the transmitting direction of the multiple-path emitter. The reception signal processing module is arranged in the optical signal receiving direction. The receiver is arranged in the light condensation direction of the reception signal processing module, and the receiver is connected with the processor. The multiple-path emitter sends infrared light signals having phase modulation in sequence according to time sequence.The emission signal processing module carries out spatial modulation on the multiple paths of infrared light signals to realize infrared light signal emission in the specific direction according to the fixed azimuth angle. The processor processes and calculates each orientation test distance information, and carries out analysis on all orientation distance information to obtain barrier distance, orientation and size information, thereby facilitating motion of a movement device and realizing an obstacle identification and detouring function.

Description

technical field [0001] The invention relates to the field of sensors, in particular to a sensor obstacle avoidance system and method capable of detecting the orientation of obstacles. Background technique [0002] In recent years, with the development of mobile robots, unmanned vehicles and drones, there is an increasing demand for obstacle avoidance sensors. Traditional sensors that can be used for obstacle avoidance include millimeter-wave radar, laser radar, binocular vision sensor, ultrasonic sensor, infrared ranging sensor, laser rangefinder, photoelectric diffuse reflection sensor, and visual sensor. [0003] The requirements of movable machinery and equipment for obstacle avoidance can also be divided into two levels: one is that it only needs to be able to detect obstacles and give a stop signal; The distance, direction, and size information of the object are given to the mobile device, and the mobile device makes a judgment based on the information to realize the g...
