Furthermore, the position of these sensors when they are mounted on the autonomous vehicle may change slightly due to vibrations of the vehicle, for example, as the vehicle is crossing the road
This can negatively affect the calibration of the sensor

Embodiment Construction

[0045] In the following description, for the purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the present invention. It will be apparent, however, that the present invention may be practiced without these specific details. In other instances, well-known structures and devices are shown in block diagram form in order to avoid unnecessarily obscuring the present invention.

[0046] In the drawings, specific arrangements or orders of schematic elements, such as those representing devices, modules, instruction blocks, and data elements, are shown for ease of description. Those skilled in the art will understand, however, that the specific order or arrangement of elements illustrated in the figures is not intended to imply that a particular order or sequence of processing, or separation of processing, is required. Furthermore, the inclusion of schematic elements in the figures is not intended to imply that such elemen...

Abstract

Systems and methods for verifying sensor calibration, among other things, are described. To verify calibration of a sensor system having several types of sensors, an object may be configured to have a substantially reflective portion such that the sensors may be separated from the substantially reflective portion, and sensor data of the sensors may be compared to verify calibration of the sensor system. And determining whether the positions of the basic reflection parts detected by the sensors are aligned or not. To calibrate the sensor system, each sensor may use and detect an object having known calibration characteristics, and the detected data may be compared to known calibration data associated with the object to determine whether each sensor is correctly calibrated.

Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS [0002] This application claims the benefit of US Provisional Application 62 / 777,637, filed October 10, 2018. technical field [0003] The present invention generally relates to verifying sensor calibration. In particular, the present specification relates to systems and methods for providing automatic verification of sensor calibration. Background technique [0004] It is becoming increasingly popular to configure a vehicle so that the vehicle has autonomous navigation capabilities. For example, drones and self-driving cars can be configured to navigate autonomously throughout an environment. These vehicles may rely on sensors such as light detection and ranging sensors, RADAR (radar) and vision-based sensors to assist these vehicles in navigating the environment. Many of these autonomous vehicles use multiple sensor types simultaneously. Furthermore, the positions of these sensors when they are mounted on the autonomous v...
