Integrating lens design with digital camera simulation
We describe a method for integrating information from lens design into image system simulation tools. By coordinating these tools, image system designers can visualize the consequences of altering lens parameters. We describe the critical computational issues we addressed in converting lens design calculations into a format that could be used to model image information as it flows through the i...
متن کاملSome Aspects of Zoom Lens Camera Calibration
Zoom lens camera calibration is an important and difficult problem for two reasons at least. First, the intrinsic parameters of such a camera change over time, it is difficult to calibrate them online. Secondly, the pin-hole model for single lens system can not be applied directly to a zoom lens system. In this paper, we address some aspects of this problem, such as determining principal point ...
متن کاملSingle Lens Stereo with a Plenoptic Camera
Ordinary cameras gather light across the area of their lens aperture, and the light striking a given subregion of the aperture is structured somewhat differently than the light striking an adjacent subregion. By analyzing this optical structure, one can infer the depths of objects in the scene, i.e., one can achieve “single lens stereo.” We describe a novel camera for performing this analysis. ...
متن کاملCamera Calibration with a Motorized Zoom Lens
This paper presents a simple and efficient method of calibrating the intrinsic camera parameters for all the lens settings of a motorized zoom lens. We fix the aperture setting and perform the camera calibration, adaptively, over the ranges of the zoom and focus settings. Bilinear interpolation is used to provide the values of the intrinsic camera parameters for those lens settings where no obs...
متن کاملDigital camera simulation.
We describe a simulation of the complete image processing pipeline of a digital camera, beginning with a radiometric description of the scene captured by the camera and ending with a radiometric description of the image rendered on a display. We show that there is a good correspondence between measured and simulated sensor performance. Through the use of simulation, we can quantify the effects ...
