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 present application relates to a sensor data encoding method, including: acquiring signal data detected by a sensor; detecting continuous zero data segments in the signal data in time sequence, and generating corresponding offset encoded data according to the continuous zero data segments; acquiring continuous The non-zero data start position after the zero data segment is used as the start position of the code segment, and the end position of the code segment is searched from the start position of the code segment, and the signal data between the start position of the code segment and the end position of the code segment are encoded to obtain Fragment coded data; return to the step of detecting continuous zero data fragments in the signal data in time order, and obtain corresponding multiple offset coded data and fragment coded data until the signal data is encoded; each offset coded data and fragment coded data are composed The target coding data corresponding to the signal data improves the transmission efficiency of the sensor data.

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 ...
