鸿蒙跨屏AI拼图游戏:分布式图像协同系统

一、项目概述

本文将基于HarmonyOS的分布式能力和AI技术,实现一个多设备协同的智能拼图游戏。系统通过手机AI将完整图片分割为碎片,并分发到多个设备(手机/平板/智慧屏)上,玩家通过跨设备协作完成拼图,实现创新的互动游戏体验。

图像分割:MindSpore语义分割模型

碎片分发:基于设备能力的智能分配

手势交互:跨设备碎片交换

三、核心代码实现
图像分割服务

// 图像分割服务
class ImageSegmentation {
private static instance: ImageSegmentation
private model: mindspore.Model | null = null

static getInstance() {
if (!ImageSegmentation.instance) {
ImageSegmentation.instance = new ImageSegmentation()
return ImageSegmentation.instance

async init() {

// 加载预训练分割模型
this.model = await mindspore.loadModel({
  path: 'models/image_segmentation.ms',
  device: 'NPU'
})

async splitImage(image: image.PixelMap, rows: number, cols: number): Promise<ImagePiece[]> {

if (!this.model) await this.init()

// 执行语义分割
const mask = await this.segment(image)

// 智能分割碎片
return this.generatePieces(image, mask, rows, cols)

private async segment(image: image.PixelMap): Promise<image.PixelMap> {

const inputTensor = await this.preprocess(image)
const outputTensor = await this.model.run(inputTensor)
return this.tensorToMask(outputTensor)

private generatePieces(image: image.PixelMap, mask: image.PixelMap, rows: number, cols: number): ImagePiece[] {

const pieces: ImagePiece[] = []
const pieceWidth = image.width / cols
const pieceHeight = image.height / rows

for (let r = 0; r < rows; r++) {
  for (let c = 0; c < cols; c++) {
    const x = c * pieceWidth
    const y = r * pieceHeight
    
    pieces.push({
      id: piece_{r}_{c},
      position: { row: r, col: c },
      image: image.crop({ x, y, width: pieceWidth, height: pieceHeight }),
      mask: mask.crop({ x, y, width: pieceWidth, height: pieceHeight })
    })

}

return pieces

}

分布式碎片管理

// 拼图状态管理器
class PuzzleManager {
private static instance: PuzzleManager
private kvStore: distributedData.KVStore | null = null
private pieces: ImagePiece[] = []

static getInstance() {
if (!PuzzleManager.instance) {
PuzzleManager.instance = new PuzzleManager()
return PuzzleManager.instance

async init() {

const kvManager = distributedData.getKVManager()
this.kvStore = await kvManager.getKVStore('puzzle_state', {
  createIfMissing: true,
  autoSync: true
})

async distributePieces(pieces: ImagePiece[], devices: DeviceInfo[]) {

this.pieces = pieces

// 根据设备能力分配碎片
const assignments = this.assignPieces(devices)

// 分发到各设备
for (const [deviceId, pieceIds] of Object.entries(assignments)) {
  const devicePieces = pieceIds.map(id => this.getPiece(id))
  await this.sendToDevice(deviceId, devicePieces)

}

private assignPieces(devices: DeviceInfo[]): Record<string, string[]> {
const assignments: Record<string, string[]> = {}
const totalPieces = this.pieces.length
let pieceIndex = 0

// 简单轮询分配算法
devices.forEach(device => {
  const capacity = this.calculateDeviceCapacity(device, totalPieces)
  assignments[device.id] = this.pieces
    .slice(pieceIndex, pieceIndex + capacity)
    .map(p => p.id)
  pieceIndex += capacity
})

return assignments

private async sendToDevice(deviceId: string, pieces: ImagePiece[]) {

// 压缩图像减少传输量
const compressedPieces = await Promise.all(
  pieces.map(async p => ({
    ...p,
    image: await p.image.compress({ quality: 80 }),
    mask: await p.mask.compress({ quality: 50 })
  }))
)

await distributedRPC.call(deviceId, 'receivePieces', {
  pieces: compressedPieces,
  sourceDevice: getDeviceId()
})

}

拼图事件同步

// 拼图事件总线
class PuzzleEventBus {
private static instance: PuzzleEventBus
private channels: Record<string, distributedData.DataChannel> = {}

static getInstance() {
if (!PuzzleEventBus.instance) {
PuzzleEventBus.instance = new PuzzleEventBus()
return PuzzleEventBus.instance

async publish(event: PuzzleEvent) {

const devices = await deviceManager.getTrustedDevices()

await Promise.all(devices.map(async device => {
  if (!this.channels[device.id]) {
    this.channels[device.id] = await distributedData.createDataChannel({
      targetDevice: device.id,
      type: distributedData.ChannelType.HIGH_PRIORITY
    })

await this.channels[device.id].send(JSON.stringify(event))

}))

async subscribe(callback: (event: PuzzleEvent) => void) {

const channel = await distributedData.createDataChannel({
  channelName: 'puzzle_events',
  type: distributedData.ChannelType.BROADCAST
})

channel.on('message', (data) => {
  callback(JSON.parse(data))
})

}

四、UI交互实现
拼图游戏主界面

@Component
struct PuzzleGameUI {
@State pieces: ImagePiece[] = []
@State placedPieces: Record<string, Position> = {}
@State currentSelection: string | null = null

build() {
Stack() {
// 拼图底板
Grid() {
ForEach(this.pieces, (piece) => {
GridItem() {
PuzzlePiece({
piece,
isPlaced: !!this.placedPieces[piece.id],
onSelect: () => this.handleSelect(piece.id)
})
})

.columnsTemplate(‘1fr 1fr 1fr’)

  .rowsTemplate('1fr 1fr 1fr')
  
  // 操作提示
  if (this.currentSelection) {
    this.SelectionOverlay()

}

.onAppear(() => {
  PuzzleEventBus.getInstance().subscribe(this.handleEvent)
})

@Builder

SelectionOverlay() {
Text(‘请选择目标位置或设备’)
.fontSize(16)
.backgroundColor(‘#00000080’)
.padding(10)
private handleSelect(pieceId: string) {

if (this.currentSelection) {
  // 交换碎片逻辑
  this.swapPieces(this.currentSelection, pieceId)
  this.currentSelection = null

else {

  this.currentSelection = pieceId

}

private async swapPieces(piece1: string, piece2: string) {
// 发布交换事件
await PuzzleEventBus.getInstance().publish({
type: ‘piece_swap’,
data: { piece1, piece2 },
source: getDeviceId()
})
private handleEvent = (event: PuzzleEvent) => {

switch (event.type) {
  case 'piece_swap':
    this.executeSwap(event.data)
    break
  case 'piece_placed':
    this.updatePlacement(event.data)
    break

}

拼图碎片组件

@Component
struct PuzzlePiece {
@Prop piece: ImagePiece
@Prop isPlaced: boolean
@Prop onSelect: () => void

build() {
Column() {
Image(this.piece.image)
.border({ width: this.isPlaced ? 3 : 0, color: ‘#0A59F7’ })
.onClick(this.onSelect)

  if (!this.isPlaced) {
    Button('放置')
      .width(60)
      .onClick(() => this.placePiece())

}

private async placePiece() {

// 验证位置是否正确
const isCorrect = await this.validatePosition()

// 发布放置事件
await PuzzleEventBus.getInstance().publish({
  type: 'piece_placed',
  data: {
    pieceId: this.piece.id,
    position: this.piece.position,
    isCorrect
  },
  source: getDeviceId()
})

}

五、性能优化方案
图像分割加速

// 高性能图像处理流水线
class ImageProcessingPipeline {
private static instance: ImageProcessingPipeline
private workerPool: Worker[] = []

static getInstance() {
if (!ImageProcessingPipeline.instance) {
ImageProcessingPipeline.instance = new ImageProcessingPipeline()
return ImageProcessingPipeline.instance

constructor() {

this.initWorkers()

private initWorkers() {

// 根据CPU核心数创建工作线程
const coreCount = device.cpu.coreCount
this.workerPool = Array(Math.max(1, coreCount - 1)).fill(0).map(() => {
  return new Worker('workers/imageProcessor.js')
})

async processForPuzzle(image: image.PixelMap): Promise<image.PixelMap> {

return new Promise((resolve) => {
  const worker = this.workerPool.pop()
  worker?.postMessage({
    type: 'puzzle_preprocess',
    image
  })
  worker?.onmessage = (processed) => {
    resolve(processed.data)
    this.workerPool.push(worker)

})

}

事件压缩传输

// 高效事件编码器
class PuzzleEventEncoder {
static encode(event: PuzzleEvent): Uint8Array {
const encoder = new TextEncoder()

switch (event.type) {
  case 'piece_swap':
    return encoder.encode(SWAP:{event.data.piece1},{event.data.piece2})
  case 'piece_placed':
    return encoder.encode(
      PLACE:{event.data.pieceId},{event.data.position.row},${event.data.position.col}
    )
  default:
    return encoder.encode(JSON.stringify(event))

}

static decode(data: Uint8Array): PuzzleEvent {
const decoder = new TextDecoder()
const str = decoder.decode(data)

if (str.startsWith('SWAP')) {
  const [_, piece1, piece2] = str.split(':')[1].split(',')
  return { type: 'piece_swap', data: { piece1, piece2 } }

if (str.startsWith(‘PLACE’)) {

  const [_, id, row, col] = str.split(':')[1].split(',')
  return { 
    type: 'piece_placed', 
    data: { 
      pieceId: id, 
      position: { row: parseInt(row), col: parseInt(col) } 

}

return JSON.parse(str)

}
