Abstract: A method calibrates a camera having image sensor having a center position. An image view projected onto the image sensor by a lens is captured. At least one image view boundary of the captured image view is detected. A projection center position corresponding to a center of the projected image view is determined in at least one dimension. Offset between the projection center position and a sensor center position is determined, defined in at least one dimension, corresponding to the center of the image sensor capturing the projected image view. The image sensor is moved in relation to the lens based on the offset in order to arrive at a substantially zero offset in at least one dimension between the center of image sensor and the center of the projected image view.

Abstract: A method is provided for switching operation of a monitoring system from a first monitoring mode to a second monitoring mode. An overview image is presented when the monitoring system is in a first monitoring mode. A direction signal is received from a control means when the monitoring system is in the first monitoring mode. A camera is directed in an absolute direction indicated by the direction signal in accordance with a first camera control scheme. The monitoring system enters into a second monitoring mode in response to receiving the direction signal presenting a detailed image view captured by the camera when directed in the direction indicated by the direction signal. When in the second monitoring mode, a camera head of the camera is moved in response to control signals from the control means in accordance with a second control scheme.
Abstract translation: 提供一种用于将监视系统的操作从第一监视模式切换到第二监视模式的方法。 当监控系统处于第一监控模式时，显示概述图像。 当监视系统处于第一监视模式时，从控制装置接收方向信号。 根据第一相机控制方案，照相机以方向信号指示的绝对方向被引导。 响应于接收到在由方向信号指示的方向指示时呈现由相机拍摄的详细图像视图的方向信号，监视系统进入第二监视模式。 当处于第二监视模式时，根据第二控制方案响应于来自控制装置的控制信号移动照相机的照相机头。

Abstract translation: 一种校准具有具有中心位置的图像传感器的相机。 捕获通过透镜投影到图像传感器上的图像视图。 检测到捕获的图像视图的至少一个图像视图边界。 在至少一个维度上确定与投影图像视图的中心对应的投影中心位置。 确定在投影中心位置和传感器中心位置之间的偏移，至少一维地限定，对应于拍摄投影图像视图的图像传感器的中心。 基于偏移，图像传感器相对于透镜移动，以便在图像传感器的中心和投影图像视图的中心之间的至少一个维度上达到基本为零的偏移。
