Abstract Binocular ranging system is widely used in military, industrial, manufacturing, and other aspects。 This can not be replaced by the application of non contact measurement and the perception of danger scene。 In this paper, the measurement principle and the realization process of binocular ranging system are studied。 And porting it to the Jetson-tk1 embedded terminal platform, make it has the advantages of small size, portability, easy to carry, and so on, in favor of the industrial development and production of binocular distance measuring instrument and design of robot vision system。

Firstly, this paper introduces the theory of binocular distance measurement based on the principle of disparity and similarity。 Then design of binocular ranging system each function module, and in the following chapter detailed describes the each module of the realization of the principle and specific process, after each module realization process and the realization of renderings。 Finally, the system is transplanted to the Jetson-tk1 embedded terminal platform, so that the use of the system more convenient, and to speed up the speed of the operation of the system。 The final system is verified to be able to complete the function of binocular distance measurement, and the error is small, which can satisfy the measurement accuracy。

The binocular distance measurement system studied in this paper has  the characteristics of high speed, high precision, strong anti-interference ability and so on。 Applicable to the cost, measuring environment and measuring accuracy of the higher requirements of the occasion。

Keywords: Binocular ranging; OpenCV; sift algorithm; parallax; Similarity principle
