Image data acquisition logic of an autonomous driving vehicle for capturing image data using cameras
First Claim
1. A sensor unit utilized in an autonomous driving vehicle, the sensor unit comprising:
- a sensor interface to be coupled to a plurality of cameras mounted on a plurality of locations of an autonomous driving vehicle (ADV);
a host interface to be coupled to a host system, wherein the host system is configured to perceive a driving environment surrounding the ADV based on at least image data obtained from the cameras and to plan a path to autonomously drive the ADV; and
a plurality of data acquisition processors, each corresponding to one of the plurality of cameras, wherein each of the data acquisition processors comprises;
a pixel alignment processor to reformat pixels of image data from an original format associated with a corresponding camera to a predetermined format, anda frame processing processor coupled to the pixel alignment processor, wherein the frame processing processor is configured to generate an image frame based on the image data received from the pixel alignment processor and to transmit the image frame to the host system.

Abstract
A sensor unit used in an ADV includes a sensor interface that can be coupled to cameras mounted on the ADV. The sensor unit further includes a host interface that can be coupled to a host system. The host system is configured to perceive a driving environment surrounding the ADV based on at least image data obtained from the cameras and to plan a path to autonomously drive the ADV. The sensor unit further includes one or more data acquisition modules corresponding to the cameras. Each data acquisition module includes a pixel alignment module and a frame processing module. The pixel alignment module is configured to reformat pixels of image data from an original format associated with the corresponding camera to a predetermined format. The frame processing module is configured to generate an image frame based on the image data and to transmit the image frame to the host system.
