In this thesis, the main research is devoted to using optical mouse’s optical sensor and application in vehicle moving distance measurement. According to optical mouse theory of picks up the contact face shadow gray scale picture and compared to be possible to judge optical mouse travel direction and the distance, we developed an optical system about lens and illumination light choice. In addition we aim at the common market passenger vehicle, sport utility vehicle, pickup truck measurement each kind of vehicles rear view mirror to the chassis height and the choice highly the size, simulates this system installment to the vehicles situation. Therefore, the comparison between simulation and experiment could be discussed with result and we may discuss the system design whether can conform with achieves the demand.
Locates holds the important status in the navigation, the navigation can have an error along with the localization accuracy, by present global positioning system use difference localization (Differential GPS: DGPS), may reach of pointing accuracy the 1~5m, but the satellite signal is easy to receive delay influence and so on thing, military exercise/war, climate/ionized layer has the signal drifting phenomenon. It can avoid the signal drifting situation production for using optical measurement system localization.
Therefore In this thesis, our supposition different road surface simulation, photographs after optical sensor element carries on the picture to compare after calculates, by the USB contact surface transmission signal to the computer, then outputs the object travel direction and the distance by the computer software. Uses our system measurement, then by way of tests analyzes obtains the data, discusses the feasibility and the accuracy from the many times experiment, and provides the basis which the future will continue to study.
