Problems solved by technology

[0003] However, in most application scenarios, intelligent robots and other related equipment need data collected by different sensors at the same time. In related technologies, according to the use of different sensors, relatively fragmented processing is used, and each sensor maintains its own data transmission. It will lead to the following problems: first, the transmission efficiency of each sensor is low, resulting in more transmission overhead; second, it is difficult for each sensor to achieve uniformity in acquisition time, and upper-layer applications need to perform time consistency on multiple sensor data The comparison, the operation is cumbersome

example 1

[0150] Example 1: Get it directly.

[0151] In this example, multiple sensors have a unified control switch, and by turning on the unified control switch, the multiple sensors can be controlled to automatically collect sensing data synchronously when the multiple sensors are working.

[0152] Wherein, in practical applications, the aforementioned synchronous switch may be controlled by a driver or software, which is not limited here.

[0153] In order to illustrate the acquisition method in this example more clearly, the synchronous switch is used as a related driving control switch, and the sensing data of sensor A and sensor B are collected as an example for illustration.

[0154] For example, if figure 2 As shown, if the sensor A and the sensor B have a synchronous control switch, when the synchronous control switch is turned on, the sensor A and the sensor B will upload the synchronously collected sensing data to the corresponding processing device. Wherein, since senso...

example 2

[0156] Example 2, indirect acquisition.

[0157] In this example, if the software or driver of the sensor cannot support the direct acquisition method shown in the first example above, at this time, after acquiring the sensing data from at least two sensors, the sensing data collected by at least two sensors Perform synchronous processing, that is, adopt the method of indirect acquisition.

[0158] It should be understood that, in this example, each acquired sensing data has a time stamp indicating the acquisition time, so that the acquired sensing data collected by at least two sensors is cached, and according to the sensing data The time stamps are compared, so as to obtain the matching sensing data collected by at least two sensors at the same time.

[0159] It should be emphasized that if image 3 As shown, the time comparison in this example is a preprocessing operation, which occurs before synchronous sensing data is called in a specific application scenario. Compared ...

Abstract

The invention provides a data generation method and device based on sensors, a data transmission method and device based on sensors, and a data processing method, device and system based on sensors. The generation method comprises: acquiring synchronously collected sensing data from at least two sensors; and generating an extended frame according to the sensing data acquired from the target sensorin the at least two sensors, wherein the data portion of the extended frame carries data content of the sensing data of the target sensor. Therefore, a plurality of synchronous sensing data is read through an extended frame, the difference of underlying hardware is shielded, and the plurality of synchronous sensing data can be acquired by calling the extended frame for one time, thereby reducingthe extra overhead and time error of multiple times of transmission of the sensing data, improving the transmission efficiency, and further improving the data processing efficiency.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a method, device and system for generating, transmitting and processing sensor-based data. Background technique [0002] At present, in applications such as intelligent robots, it is common for multiple sensors to coexist, such as vision (Camera) sensors, laser radar (Laser) sensors, inertial measurement units (IMU), ultrasonic (UltraSonic) sensors, odometer (Odometry), etc. Wait. Among them, each sensor has its own data acquisition method, application range limit and error, so intelligent robots and other first-off equipment need to collect sensing data from multiple sensors and submit them to upper-level algorithms for analysis and decision-making. Through multi-sensing After data fusion, a more optimal strategy is obtained to guide the next action. [0003] However, in most application scenarios, intelligent robots and other related equipment need data collected by d...
