Sensor data storage method and devie and sensor data reading method and device

Abstract

The invention discloses a sensor data storage method, and the method comprises the steps: carrying out the analysis of the current frame data of a sensor, and obtaining a plurality of pieces of targetattribute data; for each piece of target attribute data, obtaining an attribute corresponding to the target attribute data, and judging whether the storage space of the attribute is smaller than a first preset threshold value or not; when the storage space is smaller than a first preset threshold value, storing the target attribute data in an optimization set; when the storage space is greater than or equal to a first preset threshold, performing storage operation on the target attribute data according to the attribute and the current frame data; and then carrying out combination processing on all target attribute data in the optimization set, and carrying out storage operation on a combination processing result. The invention further discloses a sensor data reading method, a sensor datastorage device and a sensor data reading device. According to the invention, the storage space of the sensor data is reduced, and the data transmission time delay is reduced.

Description

technical field [0001] The invention relates to the field of vehicle sensor data processing, in particular to a sensor data storage and reading method and a data storage and reading device. Background technique [0002] With the continuous development of Advanced Driver Assistance Systems (ADAS, Advanced Driver Assistance Systems) technology, today's cars can implement many intelligent driving functions. The realization of these intelligent driving functions needs to be realized by means of on-board environmental perception sensors, such as on-board cameras and on-board millimeter-wave radars. However, the realization of autonomous driving functions and safety development needs to collect about 100 million hours of sensor data, so there is no damage to the sensor data. Storage presents huge challenges. [0003] Due to the requirement of lossless storage, existing sensor storage devices directly store the data in the original format when storing data. This direct storage met...
