-Designed integrated visual sensors to measure distance through detecting positions of laser facula;
-Modelled through UGNX, designed light path in the system, drew PCB of the system and printed it out ;Designed UI through Matlab to identify change of laser facula and calculated distance;
-Won the prize among all the undergraduate design thesis in School of Electronic Information and Electrical Engineering

-Designed system based on Matlab
-Used BP neural network and designed the input layer,output layer and hidden layer
-the recognition accuracy can reach more than 85% based of the amount of training samples

-Led a team of four and drew an action planning by taking every teammate's technical advantages into consideration and coordinated the whole progress;
-Designed the operation process, which is transmitting the control signal through Bluetooth from Android mobile phone to the Bluetooth module of the vehicle and then to the SCM, and different level signals were generated at different output to control the LM293 electric motor, thus realizing the movement of the vehicle;
-Succeeded in… Show more
