摘要：
The present invention provides a distance measuring system including a light source, an image sensor and a control and processing unit. The light source projects a light section onto an object with a projection angle. The image sensor senses reflected light from the light section on the object. The control and processing unit controls the light source to project the light section with the projection angle and determines a window of interest of the image sensor according to the projection angle and a predetermined system parameter. The present invention further provides a distance measuring method.
