Abstract: According to the principle of the digital camera’s forming image, we measure the distance between the points on the target and digital camera respectively, then we construct the limited equation, and calculate the position relation between target and digital camera through this limited equation, then by using the coordinate’s transformation, we transform the coordinate which takes digital camera as original points into the coordinate which takes target as original points. After that step, we could fix the coordinate which compare to the target. Finally, we finish the fixation task of the doubled-sight digital camera.

Abstract: According to the imagery coordinate’s mapping relation between the three points’(A,C,E) geometric limited condition on target surface ( length, perpendicular) and the image’s coordinate on the imagery plane surface to construct non- lineable equation models, we make use of the method of abstracting the center of a circle to get the coordinates of the three points 、 、 .In order to improve the precision and decrease the quantity of operation, we take the accelerateNewton Newton iterative method to evaluate the original numerical value by adding its repeating times to increase the precision of model, then to solve out the numerical value of coordinates of the three points A,C,E on the target’s surface, on the basis of this numerical value, we can fix the solution of the target’s surface’s equation. Try to assure the precision of the constructed model through these erroneous values, meanwhile, to make out the concrete analysis about the model’s stability.
