In a sensor fusion algorithm, the output is always zero despite valid sensor inputs. What is a probable cause?
In a sensor fusion algorithm, the output is always zero despite valid sensor inputs. What is a probable cause?
medium📝 Analysis Q7 of 15
Step-by-Step Solution
Solution:
Step 1: Understand zero output despite valid inputs
If inputs are valid but output is zero, calculation likely multiplies inputs by zero weights.Step 2: Identify cause in algorithm
Weights of zero cause the weighted sum to be zero regardless of sensor values.Final Answer:
The weights assigned to sensors are zero -> Option BQuick Check:
Zero output cause = Zero weights [OK]
Quick Trick: Check if weights are set to zero accidentally [OK]
Common Mistakes:
- Assuming hardware failure
- Ignoring weight values
- Blaming sensor distance
