Method, device and electronic equipment for shutter correction

Abstract

The present application discloses a shutter correction method, which includes controlling the shutter to close, and obtaining the current image data output by the infrared detector; replacing the current parameters of the infrared detector with the target parameters, which are based on the current image data before the current image data The parameters obtained from the collected image data; send the shutter opening command to the motor, so that the motor controls the opening of the shutter to complete the shutter calibration. In this application, the target parameters used when replacing the current parameters of the infrared detector are parameters obtained from the image data collected before the current image data, rather than calculated from the current image data. After the replacement is completed, it will open The shutter sheet completes the shutter calibration. Since the process of obtaining the target parameters takes a long time, in this application, there is no need to perform the process of obtaining the target parameters during the process of shutter calibration, so the shutter calibration time is shortened. In addition, the present application also provides a device and electronic equipment with the above advantages.

Description

technical field [0001] The present application relates to the field of imaging technology, in particular to a shutter correction method, device and electronic equipment. Background technique [0002] The shutter correction method adopted by traditional uncooled thermal imaging cameras is to adjust the configuration parameters of the infrared detector during the blocking period of the shutter, so that the average output value of the infrared detector reaches a target value after the shutter ends. When performing shutter correction in the existing method, since the calculation process of infrared detector parameters is performed in the middle of the shutter correction process, the current parameters of the infrared detector are replaced by the calculated parameters, so that the output of the infrared detector is adjusted to a suitable level , resulting in a longer shutter time. Generally, the shutter time takes more than 1 second from the start of image rigidity to the releas...

Problems solved by technology

When performing shutter correction in the existing method, since the calculation process of infrared detector parameters is performed in the middle of the shutter correction process, the current parameters of the infrared detector are replaced by the calculated parameters, so that the output of the infrared detector is adjusted to a suitable level , resulting in a longer shutter time

Generally, the shutter time takes more than 1 second from the start of image rigidity to the release of image rigidity. If it is used for driving assistance, it may cause irreparable consequences if an emergency occurs; if it is used for infrared sights, the time is too long you might miss out on a great opportunity
