A method and an apparatus for protecting a device under powerful light are disclosed. It is determined whether there is a powerful light source in an image captured by a camera device based on the number of target pixels (pixels whose gray values are larger than the first preset threshold) in the image. If so, it is indicated that the photosensitive element in the camera device is aligned with the powerful light source. In this case, the light avoidance instruction is sent, so as to cause a photosensitive element of the camera device to avoid the light source, thereby reducing the damage caused by the powerful light to the photosensitive element in the camera device.

Method and apparatus for protecting device under strong light

Disclosed is a target tracking method for an intelligent tracking high speed dome, comprising: in the process of target tracking, when the position coordinates of a newly selected target in the acquired tracking image are received, matching the position coordinates of the newly selected target in the tracking image, using the target corresponding to the position coordinates of the newly selected target in the tracking image as a current target, and extracting the characteristics of the current target; tracking the current target according to the characteristics thereof, and updating in real time the position coordinates of the current target in the tracking image; converting the updated position coordinates of the current target into speed dome identifiable horizontal rotation value P, vertical rotation value T and magnification factor value Z; adjusting in real time the magnification factor of the speed dome, and controlling in real time the rotation of the speed dome.
