In the article titled “Vehicle Detection and Ranging Using Two Different Focal Length Cameras” [1], there was an error in Figure 2 and Table 1. The authors identified that in the code used for calculating the parameter amount, the number of channels in the last layer of convolution was incorrectly set to an initial value of 255. The correct value should be 39, and Figure 2 and Table 1 are corrected to reflect this. The authors apologize for this error and confirm that it does not affect the results and the conclusions of the article. The corrected Figure 2 is as follows:

Figure 2: Lightweight YOLO network structure.

The corrected Table 1 is as follows:
