鸿蒙跨端智能填色游戏系统：分布式线稿识别与多设备配色同步方案

一、系统架构设计

!https://example.com/harmonyos-coloring-arch.png

采用三层架构：
采集层：多设备图像输入与线稿识别

逻辑层：分布式配色管理与AI推荐引擎

展示层：跨设备实时渲染与交互

二、核心模块实现
线稿识别与区域分割

// SketchProcessor.ts
import image from ‘@ohos.multimedia.image’;
import segmentation from ‘@ohos.ai.segmentation’;

interface SketchArea {
id: string;
type: ‘background’ ‘object’
‘detail’;
bounds: { x: number; y: number; width: number; height: number };
adjacency: string[]; // 相邻区域ID
export class SketchProcessor {

private segmenter: segmentation.ImageSegmenter;

async init() {
try {
this.segmenter = await segmentation.createImageSegmenter();
const config = {
model: ‘sketch_segmentation’,
device: ‘NPU’
};
await this.segmenter.init(config);
catch (err) {

  console.error(初始化失败: {err.code}, {err.message});

}

async processSketch(image: image.Image): Promise<SketchArea[]> {
const result = await this.segmenter.segment(image);
return this.convertToAreas(result);
private convertToAreas(result: segmentation.SegmentationResult): SketchArea[] {

return result.regions.map(region => ({
  id: area_${region.id},
  type: this.determineAreaType(region),
  bounds: region.bounds,
  adjacency: this.findAdjacentRegions(region, result.regions)
}));

private determineAreaType(region: segmentation.Region): SketchArea[‘type’] {

const areaRatio = region.pixelCount / (region.bounds.width * region.bounds.height);
if (areaRatio > 0.9) return 'background';
return region.pixelCount > 500 ? 'object' : 'detail';

// 其他辅助方法…

分布式配色管理

// ColorSyncManager.ts
import distributedData from ‘@ohos.data.distributedData’;
import deviceManager from ‘@ohos.distributedHardware.deviceManager’;

interface ColorAssignment {
areaId: string;
color: string; // HEX格式
deviceId: string; // 最后修改设备
timestamp: number;
export class ColorSyncManager {

private kvManager: distributedData.KVManager;
private kvStore: distributedData.KVStore;
private deviceList: deviceManager.DeviceBasicInfo[] = [];

async init() {
const context = getContext(this);
this.kvManager = distributedData.createKVManager({ context });

const options = {
  createIfMissing: true,
  encrypt: false,
  autoSync: true,
  kvStoreType: distributedData.KVStoreType.SINGLE_VERSION
};

this.kvStore = await this.kvManager.getKVStore('color_assignments', options);
this.setupDeviceListeners();

async assignColor(areaId: string, color: string) {

const assignment: ColorAssignment = {
  areaId,
  color,
  deviceId: 'current_device',
  timestamp: Date.now()
};

await this.kvStore.put(areaId, assignment);

async getColorScheme(): Promise<Record<string, string>> {

const entries = await this.kvStore.entries('area_');
return entries.reduce((scheme, [key, value]) => {
  scheme[key] = value.color;
  return scheme;
}, {});

private setupDeviceListeners() {

deviceManager.createDeviceManager('com.example.coloring', (err, manager) => {
  if (err) return;
  
  manager.on('deviceStateChange', () => {
    this.refreshDeviceList();
  });
  this.refreshDeviceList();
});

this.kvStore.on('dataChange', distributedData.SubscribeType.SUBSCRIBE_TYPE_REMOTE, 
  (changes) => {
    this.updateLocalColors(changes);
  });

// 其他方法实现…

智能配色推荐

// ColorRecommender.ts
import palette from ‘@ohos.ai.colorPalette’;

export class ColorRecommender {
private paletteGenerator: palette.ColorPalette;

async init() {
this.paletteGenerator = await palette.createColorPalette();
async generatePalette(baseColor: string): Promise<string[]> {

const options = {
  baseColor,
  count: 5,
  tone: 'complementary' // 互补色方案
};
return this.paletteGenerator.generate(options);

async recommendForSketch(sketch: SketchArea[], theme: string): Promise<Record<string, string[]>> {

const recommendations: Record<string, string[]> = {};
const basePalette = await this.getThemeBase(theme);

for (const area of sketch) {
  const base = basePalette[area.type] || '#FFFFFF';
  recommendations[area.id] = await this.generatePalette(base);

return recommendations;

private getThemeBase(theme: string): Record<string, string> {

const themes = {
  nature: { background: '#8BBA94', object: '#4A785E', detail: '#F5F5DC' },
  ocean: { background: '#1E88E5', object: '#0D47A1', detail: '#B3E5FC' }
  // 其他主题...
};
return themes[theme] || themes.nature;

}

三、主页面实现（ArkUI）

// ColoringGame.ets
import { SketchProcessor } from ‘./SketchProcessor’;
import { ColorSyncManager } from ‘./ColorSyncManager’;
import { ColorRecommender } from ‘./ColorRecommender’;

@Entry
@Component
struct ColoringGame {
@State sketchAreas: SketchArea[] = [];
@State colorAssignments: Record<string, string> = {};
@State recommendations: Record<string, string[]> = {};
@State currentTheme: string = ‘nature’;

private sketchProcessor = new SketchProcessor();
private colorSync = new ColorSyncManager();
private colorRecommender = new ColorRecommender();
private canvasContext?: CanvasRenderingContext2D;

async aboutToAppear() {
await this.sketchProcessor.init();
await this.colorSync.init();
await this.colorRecommender.init();
this.loadDefaultSketch();
async loadDefaultSketch() {

const sketchImage = $r('app.media.default_sketch');
this.sketchAreas = await this.sketchProcessor.processSketch(sketchImage);
this.recommendations = await this.colorRecommender.recommendForSketch(this.sketchAreas, this.currentTheme);
this.loadColorAssignments();

async onAreaSelect(areaId: string) {

const colors = this.recommendations[areaId];
// 显示颜色选择面板
this.showColorPicker(areaId, colors);

async onColorSelect(areaId: string, color: string) {

await this.colorSync.assignColor(areaId, color);
this.renderArea(areaId, color);

build() {

Column() {
  // 画布区域
  Canvas(this.onCanvasReady)
    .width('100%')
    .height('60%')
    .onClick((event) => this.handleCanvasClick(event))
  
  // 配色推荐面板
  ColorRecommendations({
    recommendations: this.recommendations,
    onSelect: (areaId, color) => this.onColorSelect(areaId, color)
  })
  
  // 主题选择器
  ThemeSelector({
    current: this.currentTheme,
    themes: ['nature', 'ocean', 'fantasy'],
    onChange: (theme) => {
      this.currentTheme = theme;
      this.updateRecommendations();

})

}

// 其他方法实现…
@Component

struct ColorRecommendations {
@Prop recommendations: Record<string, string[]>;
@Param onSelect: (areaId: string, color: string) => void;

@State activeArea?: string;

build() {
Column() {
if (this.activeArea) {
Text(为区域 ${this.activeArea} 选择颜色:)
.fontSize(16)

    Grid() {
      ForEach(this.recommendations[this.activeArea], (color) => {
        GridItem() {
          ColorButton(color)
            .onClick(() => this.onSelect(this.activeArea!, color))

})

.columnsTemplate(‘1fr 1fr 1fr 1fr 1fr’)

else {

    Text('点击画布区域选择颜色')

}

}

@Component
struct ColorButton {
@Prop color: string;
@Param onClick: () => void;

build() {
Column() {
// 颜色方块
.backgroundColor(this.color)

.width(40)
.height(40)
.onClick(() => this.onClick())

}

四、跨设备协同关键实现
实时填色同步

// 在ColorSyncManager中添加
private updateLocalColors(changes: distributedData.DataChange[]) {
changes.forEach(({ key, value }) => {
if (key.startsWith(‘area_’)) {
this.colorAssignments[key] = value.color;
this.triggerRerender(key, value.color);
});

private triggerRerender(areaId: string, color: string) {

// 通知UI更新特定区域
postMessageToUI({
type: ‘color_update’,
areaId,
color
});

多设备协作模式

// CollaborativeMode.ts
export class CollaborativeMode {
private colorSync: ColorSyncManager;

constructor(colorSync: ColorSyncManager) {
this.colorSync = colorSync;
async assignAreasToDevices(areaIds: string[]) {

const devices = await this.colorSync.getAvailableDevices();
areaIds.forEach((areaId, index) => {
  const device = devices[index % devices.length];
  this.assignAreaToDevice(areaId, device.deviceId);
});

private async assignAreaToDevice(areaId: string, deviceId: string) {

try {
  await this.colorSync.syncAssignment(areaId, deviceId);

catch (err) {

  console.error(分配区域失败: {err.code}, {err.message});

}

冲突解决策略

// 在ColorSyncManager中添加
private conflictResolver(remote: ColorAssignment, local: ColorAssignment): ColorAssignment {
// 采用时间戳优先策略
return remote.timestamp > local.timestamp ? remote : local;
private setupConflictHandler() {

this.kvStore.on(‘conflict’, (key, local, remote) => {
if (key.startsWith(‘area_’)) {
const resolved = this.conflictResolver(remote, local);
this.kvStore.put(key, resolved);
});

五、性能优化方案
区域数据压缩

// 在SketchProcessor中添加
private compressAreaData(areas: SketchArea[]): CompressedArea[] {
return areas.map(area => ({
i: area.id,
t: area.type.charAt(0), // ‘b’‘o’
‘d’
b: {area.bounds.x},{area.bounds.y},{area.bounds.width},{area.bounds.height},
a: area.adjacency.join(‘,’)
}));

渐进式加载

// 在主页面中添加
private async loadSketchProgressively() {
const chunks = this.splitIntoChunks(this.sketchAreas, 5);
for (const chunk of chunks) {
await this.renderAreas(chunk);
await new Promise(resolve => setTimeout(resolve, 100)); // 每批间隔100ms
}

本地缓存策略

const recommendationCache = new Map<string, string[]>();

async getCachedRecommendations(areaId: string, theme: string): Promise<string[]> {
const cacheKey = {areaId}_{theme};
if (recommendationCache.has(cacheKey)) {
return recommendationCache.get(cacheKey)!;
const fresh = await this.colorRecommender.generateForArea(areaId, theme);

recommendationCache.set(cacheKey, fresh);
return fresh;

六、应用场景扩展
教育模式

class EducationMode {
async showColorTheory(areaId: string) {
// 展示色彩理论教学
}

AR预览功能

class ARPreview {
async showInAR(colorScheme: Record<string, string>) {
// 在AR中预览填色效果
}

社交分享

class SocialSharing {
async shareToCommunity(artwork: ArtworkData) {
// 分享到社交平台
}

打印集成

class PrintIntegration {
async prepareForPrint(artwork: ArtworkData) {
// 准备打印格式
}

七、完整调用示例

async function startCollaborativeSession() {
const sketchProcessor = new SketchProcessor();
const colorSync = new ColorSyncManager();
const recommender = new ColorRecommender();

await Promise.all([
sketchProcessor.init(),
colorSync.init(),
recommender.init()
]);

const sketch = await sketchProcessor.processSketch($r(‘app.media.sketch’));
const palette = await recommender.generatePalette(‘#4285F4’);

// 分配区域给不同设备
const collabMode = new CollaborativeMode(colorSync);
await collabMode.assignAreasToDevices(sketch.map(area => area.id));

console.info(‘协作填色会话已启动’);

本系统充分利用HarmonyOS 5的分布式能力，实现了以下创新功能：
多设备实时填色协作：不同用户可同时为同一线稿的不同区域上色

智能配色推荐：基于色彩理论的AI推荐引擎

冲突自动解决：时间戳优先的数据一致性保障

自适应渲染：根据设备性能动态调整渲染质量

开发者可以基于此框架扩展更多创意功能，如：
结合AR的实时预览

动态色彩混合效果
