Abstract: The disclosure describes an autotuning framework for tuning an image signal processing (ISP) module of an autonomous driving vehicle (ADV). The autotuning framework can generate different sets of parameter values using a variety of optimization algorithms to configure the ISP module. Each processed image generated by the ISP module configured with the different sets of parameter values is compared by an ISP module testing device with a reference image stored therein to generate an objective core measuring one or more differences between each of the processed images and the reference image. The objective scores and the corresponding sets of parameter values are stored in a database. Different sets of optimal parameter values for different environments can be selected from the database, and uploaded to a cloud database for use by an ADV, which can select a different set of ISP parameter values based on an environment that the ADV is travelling in.

Abstract: A computing device may obtain one or more raw images captured from sensors of an autonomous driving vehicle (ADV). The computing device may apply one or more signal processing parameters to one or more raw images, resulting in one or more processed images. The computing device may apply an object detection algorithm of the ADV to the one or more processed images. The computing device may determine a score of the object detection algorithm as applied to the one or more processed images. One or more optimized signal processing parameters may be determined based on the score of the object detection algorithm and the signal processing parameter. The one or more optimized signal processing parameters may be used to configure the ADV for use during autonomous driving.
