| Summary: | 碩士 === 國立虎尾科技大學 === 航空與電子科技研究所 === 99 === In order to allow patient with lower extremity impairment to recover and regain its act, in this thesis, we design an intelligent walking rehabilitation system. The system uses a video camera as input device to measurement the movement of a walking patient. In the image grabbed by the video camera, we defined both the start and stop regions. When the patient appears in these two regions, the difference motion analysis method is applied to calculate the amount of intensity changed in the region to act the walking machine start or stop. This system also has an adaptive speed control function. This function is achieved by using the optical flow concept, which uses the block matching algorithm to calculate the difference of moving vector. By this function, the speed of the patient moving can be estimated.
Approved by experiments, this system can automatic adjust the motor speed of the walking machine to adaptive the different speed of patient walking on the walking machine and accomplish the goal of self-rehabilitation at home.
