Is this a bug? I think there should be an assignment sentence.

Hi Guidance Team,
In the source code, Guidance-SDK/demo/obstacle_bypass/discontinuity-balance_strategy/src/dji_sdk/src/dji_sdk_node.cpp, from line 279 to 283. The variable neighbor_count was defined and initialized as zero but never used before line 282. However, it act as a Denominator in line 282. Is this a bug? I think we should add else {neighbor_count++ } after 279, am I right? Looking forward to your confirmation.

279    if(1.0 - (a_x*b_x + a_y*b_y)/(pow(b_x, 2) + pow(b_y, 2)) > OF_MARGIN) neighbor_diff++;
280                                 }
281                             }
282 if((double)neighbor_diff/(double)neighbor_count > DISC_MARGIN)
283  {
