Embodiment Construction

[0036] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0037] figure 1 It is an application environment diagram of the sensor data encoding method in one embodiment. Such as figure 1 As shown, the application environment includes a sensor 110 and a host computer 120. The sensor 110 acquires the detected signal data, detects the continuous zero data segments in the signal data in time sequence, and generates corresponding offset coded data according to the continuous zero data segments; The non-zero data start position after the continuous zero data segment is used as the start position of the code segment, and the end positi...

Abstract

The invention relates to a sensor data encoding method. The method comprises the following steps: acquiring signal data detected by a sensor; detecting continuous zero data fragments in the signal data according to a time sequence, and generating corresponding offset coded data according to the continuous zero data fragments; obtaining a non-zero data initial position after the continuous zero data segment as a coding segment initial position, searching a coding segment end position from the coding segment initial position, and coding signal data between the coding segment initial position andthe coding segment end position to obtain segment coding data; returning to the step of detecting the continuous zero data segment in the signal data according to the time sequence to obtain a plurality of corresponding offset coded data and segment coded data until the signal data is coded; the offset coded data and the segment coded data forming target coded data corresponding to the signal data, and the sensor data transmission efficiency is improved.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a sensor data encoding method and device, electronic equipment, and a computer-readable storage medium. Background technique [0002] In recent years, with the development of computer technology, Time of Flight (ToF, Time of Flight) sensors are used in various fields. The large amount of data collected by the sensor is a big factor that limits the high frame rate sampling of the sensor. For example, for a single photon avalanche diode (SPAD, Single Photon Avalanche Diode) array, the amount of data generated by a 60X80 pixel SPAD array can reach 39,321,600 bps, such a data volume can only transmit 27 frames at most for a 1Gbps high-speed Mobile Industry Processor Interface (MIPI, Mobile Industry Processor Interface) bus. Therefore, in the process of data transmission, it not only occupies a huge data bandwidth but also affects the data sampling efficiency, which will ...
