Embodiment Construction

[0033] The following will clearly and completely describe the technical solutions in the embodiments of this specification with reference to the drawings in the embodiments of this specification. Obviously, the described embodiments are part of the embodiments of this specification, not all of them. Based on the embodiments in this specification, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of this specification.

[0034] The flow charts shown in the drawings are just illustrations, and do not necessarily include all contents and operations / steps, nor must they be performed in the order described. For example, some operations / steps can be decomposed, combined or partly combined, so the actual order of execution may be changed according to the actual situation.

[0035] Some implementations of this specification will be described in detail below with reference to the accompanying drawings. In t...

Abstract

The present invention relates to a sensing system, a sensing device, a control method thereof, a mobile platform, and a storage medium. The control method comprises receiving an interrupt request sentby a second sensing system (700), and determining an interrupt time at which the interrupt request is received (S110); receiving a synchronization timestamp sent by the second sensing system (700), wherein the synchronization timestamp is a moment recorded according to a second local time axis when the interrupt request is sent (S120); and determining a time deviation value according to the interruption time and the synchronization timestamp (S130).

Description

technical field [0001] This specification relates to the technical field of sensors, and in particular to a sensing system, a sensing device and a control method thereof, a movable platform and a storage medium. Background technique [0002] At present, embedded systems are becoming more and more complex, and the same embedded system may contain multiple control chips, multiple different operating systems (such as linux, RTOS), and sensors with multiple functions. Different systems collect environmental perception data through sensors and transmit the data to different upper-layer applications. At the same time, due to different applications, the link delay of sensor data to different applications is often unpredictable. However, in application scenarios with high precision and high stability requirements such as drones, strict data synchronization is particularly important. [0003] For example, in embedded systems such as aerial photography aircraft, due to the large numb...
