receiving, from a height sensor located at a rear portion of the cab, a measured value indicative of a height of the rear portion of the cab relative to the chassis; and

correcting or compensating for movements of or misalignment between the first sensor and the second sensor by calibrating the first sensor data and the second sensor data based on the measured value.

10. The system of claim 9 , wherein the height sensor comprises an ultrasonic distance sensor, a laser distance sensor, a linear potentiometer, or a rotary potentiometer.

11. The system of claim 9 , wherein the first sensor is located on a roof of the cab, wherein the second sensor is located on a hood of the semi-trailer truck.

12. The system of claim 11 , wherein a front portion of the cab is attached with a first pivoting mount to the chassis, the first pivoting mount comprising the first pivot, wherein a rear portion of the cab is suspended on or coupled to an air spring.

13. The system of claim 11 , wherein a front portion of the cab is attached with a first pivoting mount to the chassis, the first pivoting mount comprising the first pivot, wherein a front portion of the hood is attached with a second pivoting mount to the chassis, the second pivoting mount comprising the second pivot.

14. The system of claim 13 , wherein a latch couples a rear portion of the hood to the front portion of the cab.

15. The system of claim 9 ,

wherein the first sensor comprises a camera and the first sensor data comprises a camera image, and

wherein the second sensor comprises a light detection ranging (LiDAR) sensor and the second sensor data comprises LiDAR data.

16. The system of claim 9 , wherein the first sensor and the second sensor move in opposite directions in response to receiving a physical stimulus, wherein one of the first sensor and the second sensor moves upward relative to a plane formed by the chassis, wherein the other one of the first sensor and the second sensor moves downward relative to the plane.

17. A non-transitory computer readable storage medium having code stored thereon, the code, when executed by a processor, causing the processor to implement a method comprising:

receiving, from a first sensor located on a cab of a semi-trailer truck, a first sensor data, wherein the first sensor is rotatable relative to a first pivot of a chassis of the semi-trailer truck;

receiving, from a second sensor located on a hood of the semi-trailer truck, a second sensor data, wherein the second sensor is rotatable relative to a second pivot of the chassis, a position of the second pivot being different from a position of the first pivot;

receiving, from a height sensor located at a rear portion of the cab, a measured value indicative of a height of the rear portion of the cab relative to the chassis; and
