Real-Time Signal Processing Method for Infrared Sensor Arrays
Infrared sensor arrays is a new type of apperceiving system of robots, which are made up of large-area and flexible sensors with data processing capabilities. In order to meet the requirement of real-time obstacle avoidance, sensors which can be covered on the surface of robots were designed to apperceive the environment and provide the environmental information by the infrared sensors and the controlling circuit on them. To get rid of the environmental disturbance to the infrared sensors, and to meet the requirement of system precision, real time and stability, a kind of reconfigurable architecture based on DSP+FPGA was designed and a kind of spectrum analyzing method based on FFT (Fast Fourier Transform) was used. Tests of the system with different color papers as the measured subjects showed that the output of sensor arrays had low sensitivity.
