Research On Speed Measurement Of Rolling Shurrer Digital Camera

By rolling shutter imaging characteristics of principle study, and the current digital camera technology in the speed of application development, comprehensive comparison can be found, currently widely used in China's video speed systems are the presence of functional single, can only measure the average speed of moving objects, can not provide instantaneous velocity. The objective of this topic is to develop a set of multiple functions into one, cost less than similar products velocimetry. This paper introduces the digital camera rolling shutter imaging works and imaging features, Second, research and technology derived velocity of the foundation and the necessary work-Digital camera calibration algorithm, proposed based on rolling shutter speed digital cameras means more speed to achieve the algorithm is derived. At last the rolling shutter speed digital camera test. Experimental results show that the method proposed in this paper-the use of digital camera rolling shutter shooting moving objects will distort the image to calculate the speed of a moving object method, the calculation error of less than 3%, with user-friendly implementation of the feasibility. This calculation method can make low-cost, low power digital camera into a new type of speed sensor.
