In order to learn the language well, reading should be attached adequate importance. Reading ability, as a basic requirement in learning a foreign language, can be developed by doing comprehension exercises. The key to improve reading lies in reading speed. The faster you read, the more you are able to grasp the main point of a text. However, many people have obstacles in reading. This paper summarizes the main barriers in reading fast and puts forward some strategies for improving reading speed.展开更多

In this scheme, firstly, the image information of the mobile robot path was captured by the binocular camera; then the feature points were extracted and corresponding matched using SURF to the binocular images as the undetected obstacles; finally fixed the position of the objective by the parallax between the matching points combining with the binocular vision calibration model. Theoretical derivation and experimental results show that this scheme is more accurate for the detection and navigation of the interest points. It has fast matching speed and high accuracy and low error. So, it has certain practical effect and popularizing value for the mobile robot real-time obstacle avoidance and navigation.展开更多
