Abstract
The application discloses Systems and methods for a data synchronization. The system may include a receiving module, an instruction generating module and a sending module. The receiving module may be configured to receive the first instruction. The first instruction may be used to instruct the start of data acquisition of the system. In response to receiving the first instruction, the instruction generating module may be configured to generate a second instruction. The second instruction may be used to trigger at least two sensors to acquire data. The sending module may be configured to send second instruction to at least two sensors respectively based on the first delay. The first delay causes the time difference between at least two sensors starting to acquire data less than the first preset threshold.
Claims17
A system, comprising:
- at least one storage device storing executable instruction, and
- at least one processor in communicating with the at least one storage device, wherein when executing the executable instruction, the processor causes the system to perform operations, including:
- receiving a first instruction, the first instruction being used to instruct a start of data acquisition of the system;
- in response to receiving the first instruction, generating a second instruction, the second instruction being used to trigger a first sensor and a second sensor to acquire data;
- and
- sending the second instruction to the first sensor and the second sensor respectively based on a first delay, the first delay causing a time difference between the first sensor and the second sensor starting to acquire data less than a first preset threshold, wherein the first sensor is an image sensor, the first delay being a total duration between the image sensor receiving the second instruction and starting to acquire image frames, and a time interval between the image frames of the image sensor is greater than or equal to a data solution output time of the second sensor,
- wherein in response to receiving the first instruction, the operations further include:
- generating a third instruction, the third instruction being used to instruct the first sensor and the second sensor to send acquired data;
- and
- sending the third instruction to the first sensor and the second sensor respectively based on a second delay, the second delay causing a time difference between the first sensor and the second sensor sending the acquired data less than a second preset threshold.
A method, comprising:
- receiving a first instruction, the first instruction being used to instruct a start of data acquisition of the system;
- in response to receiving the first instruction,
- generating a second instruction, the second instruction being used to trigger a first sensor and a second sensor to acquire data;
- generating a third instruction, the third instruction being used to instruct the first sensor and the second sensor to send acquired data
- sending the second instruction to the first sensor and the second sensor respectively based on a first delay, the first delay causing a time difference between the first sensor and the second sensor starting to acquire data less than a first preset threshold, wherein the first sensor is an image sensor, the first delay being a total duration between the image sensor receiving the second instruction and starting to acquire image frames, and a time interval between the image frames of the image sensor is greater than or equal to a data solution output time of the second sensor;
- and
- sending the third instruction to the first sensor and the second sensor respectively based on a second delay, the second delay causing a time difference between the first sensor and the second sensor sending the acquired data less than a second preset threshold.
