Problems solved by technology

[0003] Currently existing data collection systems are usually unable to directly collect signals from sensors such as cameras, radars, and lidars that come with self-driving vehicles
After the data acquisition system is connected to the sensor of the self-driving vehicle, the serial differential signal from the camera and the Ethernet signal from the radar / lidar can only be sent to the data acquisition system, but cannot be sent to the self-driving / ADAS controller
To meet the data acquisition requirements of the autopilot system / ADAS system and the data acquisition system at the same time, it is necessary to add additional identical sensors to collect signals at positions close to these sensors, and connect the data acquisition system to these additional sensors. The acquisition system uses these collected signals to approximately restore the signals processed by the original vehicle's automatic driving system / ADAS system, which will greatly increase the cost of automatic driving data collection, and the additional installed sensors cannot completely restore the automatic driving system / ADAS system processed signal

Abstract

The invention provides an automatic driving data collecting and forwarding device and method. The device comprises a logic circuit module and also comprises a video deserializer, a video serializer, avideo compression processor and an Ethernet transceiver, wherein the video deserializer, the video serializer, the video compression processor and the Ethernet transceiver are connected to the logiccircuit module. The method comprises the following steps: receiving first video data sent by a vehicle-mounted camera and carrying out format conversion on the first video data; synchronously copyingthe first video data into at least two pieces of second video data, performing format conversion on one piece of second video data, and sending the second video data to an advanced driving assistancesystem; encoding and compressing the other part of the second video data, and sending the encoded and compressed second video data to a computer; receiving first Ethernet data of an Ethernet sensor; and synchronously copying the first Ethernet data into at least two parts of second Ethernet data, and respectively sending the at least two parts of second Ethernet data to the advanced driving assistance system and the computer.

Description

technical field [0001] The present invention mainly relates to the field of automatic driving systems, in particular to an automatic driving data collection and forwarding device and method. Background technique [0002] Self-driving cars or cars with advanced driver assistance (ADAS) functions usually need to be equipped with multiple sensors such as multiple cameras, millimeter-wave radars, lidars, and high-precision positioning systems. The signal is transmitted to the vehicle's automatic driving controller / ADAS controller through different buses for processing, and then communicates with other ECUs (Electronic Control Unit, Electronic Control Unit) of the vehicle to realize the vehicle's automatic driving / ADAS function. When developing and testing the automatic driving controller / ADAS controller, the above sensor signals need to be collected and stored to provide designers with data analysis. [0003] Currently existing data acquisition systems are usually unable to dir...
