keystone distortion

简明释义

梯形失真

英英释义

Keystone distortion refers to the optical distortion that occurs in images taken with a camera or projector when the lens is not parallel to the subject, causing the image to appear trapezoidal rather than rectangular.

拱心失真是指在使用相机或投影仪拍摄图像时,当镜头与主题不平行时发生的光学失真,导致图像呈现梯形而非矩形。

例句

1.To correct the keystone distortion, we adjusted the angle of the projector.

为了纠正梯形失真,我们调整了投影仪的角度。

2.Using software tools, we were able to minimize the keystone distortion in our digital images.

通过使用软件工具,我们能够最小化数字图像中的梯形失真

3.In architectural presentations, keystone distortion can misrepresent the intended design.

在建筑展示中,梯形失真可能会误导设计意图。

4.When projecting the image, the technician noticed a significant keystone distortion that affected the overall clarity.

在投影图像时,技术人员注意到明显的梯形失真,这影响了整体清晰度。

5.The photographer had to retouch the image due to keystone distortion caused by an uneven angle.

由于不均匀的角度造成的梯形失真,摄影师不得不对图像进行修饰。

作文

In the realm of photography and architecture, the term keystone distortion refers to a common optical phenomenon that occurs when a camera is tilted upwards or downwards. This distortion results in images where the vertical lines appear to converge, creating a trapezoidal effect instead of maintaining their straight, parallel appearance. Understanding keystone distortion is crucial for photographers and architects alike, as it can significantly influence the perception of a structure's design and proportions.When capturing images of tall buildings or monuments, photographers often find themselves in situations where they must tilt their camera to include the entire subject within the frame. While this technique can yield stunning visuals, it also introduces keystone distortion, which can detract from the intended aesthetic of the photograph. For instance, the iconic image of a skyscraper might be marred by the distorted lines that make the building look as if it is leaning backward. This effect can mislead viewers about the actual shape and stability of the structure.Architects, on the other hand, must be aware of keystone distortion during the design phase to ensure that their creations are accurately represented in photographs and renderings. When presenting designs to clients or stakeholders, architects often rely on visual aids that showcase their work. If these images suffer from keystone distortion, the final product may not align with the initial vision, leading to misunderstandings and dissatisfaction.To mitigate the effects of keystone distortion, photographers can employ various techniques. One effective method is to use a tilt-shift lens, which allows for adjustments in perspective without the need to angle the camera. This specialized lens can help maintain straight lines and accurate proportions, resulting in a more faithful representation of the subject. Additionally, post-processing software provides tools to correct keystone distortion in images after they have been captured. By using these tools, photographers can straighten lines and restore the intended composition of their photographs.In architectural practice, understanding keystone distortion extends beyond simply correcting images. It also informs the way architects conceptualize space and structure. By considering how their designs will be photographed, architects can create buildings that not only function well but also photograph beautifully. This foresight can enhance the impact of their work in promotional materials, portfolios, and presentations.In conclusion, keystone distortion is an important concept in both photography and architecture. Recognizing its implications allows professionals in these fields to produce more accurate and visually appealing representations of their work. Whether through the use of specialized equipment or post-processing techniques, managing keystone distortion can lead to improved communication and understanding of architectural designs. Ultimately, being mindful of this phenomenon enhances the overall quality of visual representations, ensuring that the beauty and integrity of structures are preserved in every image captured.

在摄影和建筑领域,术语keystone distortion(基石畸变)指的是一种常见的光学现象,当相机向上或向下倾斜时会发生。这种畸变导致图像中的垂直线条看起来趋于汇聚,形成梯形效果,而不是保持其直线和平行外观。理解keystone distortion对摄影师和建筑师来说至关重要,因为它会显著影响对结构设计和比例的感知。当捕捉高楼大厦或纪念碑的图像时,摄影师常常发现自己必须倾斜相机以将整个主题纳入画框。虽然这种技术可以产生惊人的视觉效果,但它也引入了keystone distortion,可能会削弱照片的预期美感。例如,标志性的摩天大楼图像可能会因扭曲的线条而显得向后倾斜。这种效果可能会误导观众对实际形状和稳定性的理解。另一方面,建筑师在设计阶段必须意识到keystone distortion,以确保他们的作品在照片和渲染中得到准确表现。当向客户或利益相关者展示设计时,建筑师通常依赖于展示其工作的视觉辅助工具。如果这些图像受到keystone distortion的影响,则最终产品可能与最初的愿景不符,从而导致误解和不满。为了减轻keystone distortion的影响,摄影师可以采用各种技术。一种有效的方法是使用倾斜移位镜头,它允许在不需要倾斜相机的情况下进行透视调整。这种专业镜头可以帮助保持直线和准确的比例,从而产生更忠实于主题的表现。此外,后期处理软件提供了纠正图像中keystone distortion的工具。通过使用这些工具,摄影师可以拉直线条,恢复照片的预期构图。在建筑实践中,理解keystone distortion不仅限于简单地修正图像。它还影响建筑师构思空间和结构的方式。通过考虑他们的设计将如何被拍摄,建筑师可以创造出不仅功能良好,而且拍摄效果优美的建筑。这种前瞻性可以增强他们在宣传材料、作品集和演示中的工作影响力。总之,keystone distortion是摄影和建筑中一个重要的概念。认识到其影响使这些领域的专业人士能够更准确和视觉上更具吸引力地呈现他们的作品。无论是通过使用专业设备还是后期处理技术,管理keystone distortion都能提高沟通和理解建筑设计的效果。最终,关注这一现象提升了视觉表现的整体质量,确保每一幅捕捉到的图像都保留了结构的美感和完整性。
