🎯 Overview

BaoPhuCam solves the camera placement optimization problem for surveillance systems. Given a master plan with boundaries, buildings, and trees, the system calculates optimal camera positions that maximize coverage while minimizing the number of cameras required.

Real-World Application: Jackfruit Village

The system has been successfully deployed for the Jackfruit Village residential area, optimizing surveillance coverage for:

• 🏘️ Private residential zones
• 🌊 Flood-prone areas and water features
• 🌳 Landscaped areas with tree obstacles
• 🏢 Building structures
• 🚶 Pathways and circulation routes

Problem Statement

Challenge: Place the minimum number of cameras to achieve maximum area coverage while:

• Avoiding line-of-sight obstructions from buildings
• Accounting for partial visibility reduction from trees
• Respecting area boundaries
• Maintaining optimal camera spacing
• Prioritizing critical zones (flood plains, entry points)

Solution: An iterative optimization algorithm that progressively refines camera positions based on coverage analysis, obstacle detection, and efficiency metrics.

Step-by-Step Process

1. Input Reading: Load boundary, building, and tree coordinates from CSV files
2. Grid Creation: Convert coordinates to grid-based representation (width × height)
3. Obstacle Mapping: Mark buildings (hard blocks) and trees (soft blocks) on grid
4. Camera Loading: Read pre-calculated camera positions from CSV
5. Coverage Calculation: For each camera:
   • Cast rays to all grid edges using Bresenham's algorithm
   • Calculate acceptability score for each visible cell
   • Account for obstacles and camera range
6. Acceptability Scoring:
   • 1.0 = Full coverage (clear line-of-sight within range)
   • 0.5 = Partial coverage (tree obstruction or beyond range)
   • 0.0 = No coverage (building obstruction or outside boundary)
7. Visualization: Generate color-coded output image

🔬 Algorithm Details

Core Algorithms

1. Bresenham's Line Algorithm

Purpose: Calculate line-of-sight between camera and target points

Implementation: algo_bresenham.py

def bresenham_fromCenter(x0, y0, x1, y1):
    """
    Returns list of (x,y) points along the line from (x0,y0) to (x1,y1)
    Used to check obstacles between camera and coverage point
    """
    # Bresenham's line drawing algorithm
    # Returns all grid cells intersected by the line

Usage: For each camera, cast rays to all grid edges to determine visible cells.

2. Coverage Acceptability Calculation

Algorithm: For each point along the line-of-sight:

def calculate_acceptability_onALine(pointList, range_of_camera, 
                                    data_cell_isInsideBoundary,
                                    data_cell_isBuilding, 
                                    data_cell_isTree, 
                                    data_cell_acceptability):
    prop = 1.0  # Start with full coverage
    x_first, y_first = pointList[0]
    isBeyondNormalRange = False
    
    for x, y in pointList:
        # Check if beyond camera range
        if not isBeyondNormalRange:
            distance_sq = (x - x_first)**2 + (y - y_first)**2
            if distance_sq > range_of_camera**2:
                isBeyondNormalRange = True
                prop /= 2  # Reduce to 50% beyond range
        
        # Stop if outside boundary
        if not data_cell_isInsideBoundary[x, y]:
            break
        
        # Stop if building obstruction
        if data_cell_isBuilding[x, y]:
            break
        
        # Reduce by 50% if tree obstruction
        if data_cell_isTree[x, y]:
            prop /= 2
        
        # Update acceptability score
        if data_cell_acceptability[x, y] < prop:
            data_cell_acceptability[x, y] = prop

Acceptability Scores:

• 1.0: Full coverage (clear line-of-sight, within range)

Viewing Progressive Results

Each test's collision/ directory shows how coverage improves as cameras are added:

test_4/collision/after_5_cameras.png   # After 5 cameras
test_4/collision/after_10_cameras.png  # After 10 cameras
test_4/collision/after_15_cameras.png  # After 15 cameras
test_4/collision/after_20_cameras.png  # After 20 cameras
