摘要： Devices, systems, and methods for hardware-based time synchronization for heterogenous sensors are described. An example method includes generating a plurality of input trigger pulses having a nominal pulse-per-second (PPS) rate, generating, based on timing information derived from the plurality of input trigger pulses, a plurality of output trigger pulses, and transmitting the plurality of output trigger pulses to a sensor of a plurality of sensors, wherein a frequency of the plurality of output trigger pulses corresponds to a target operating frequency of the sensor, wherein, in a case that a navigation system coupled to the synchronization unit is functioning correctly, the plurality of input trigger pulses is generated based on a nominal PPS signal from the navigation unit, and wherein, in a case that the navigation system is not functioning correctly, the plurality of input trigger pulses is generated based on a simulated clock source of the synchronization unit.

摘要： Provided in the present disclosure are an image brightness statistical method and an imaging device, related to the image processing field. The method includes: acquiring the bit width of a pixel brightness value of an image to be processed and a maximum acceptable bit width of a block random access memory; dividing bits of each pixel of said image into multiple groups of bits so that the bit width of each group is less than or equal to the maximum acceptable bit width; performing brightness histogram statistics based on the pixel data of same groups to produce a brightness histogram component corresponding to each group; determining brightness evaluation value components of each groups based on the brightness histogram components corresponding to the groups and the number of pixels of said image; and determining a brightness evaluation value of said image based on the brightness evaluation value components.
