This paper firstly analyzes the reliability Influence factors of the embedded software, then puts forward an embedded software reliability evaluation model based on BP neural network, finally the preliminary application and verification of the model is given.

In this paper, a method on monocular vision for spatial position is presented. The geometric model of digital camera is built and decomposed to intrinsic and extrinsic parameter matrixes under a certain assumption. Firstly, the intrinsic parameter matrix of camera is determined. Then, the extrinsic parameter matrix is solved according to the information of image. The edge detection operators are worked and in order to detect the accuracy of this method, the point of some feature points are obtained by using the principle of least squares. Compared with the conventional calibration method, this method is simple, fast and robust.

Gong lauds a study of software developers whose intricate work shapes our world.
