Embodiment 1

[0028] This embodiment provides a dynamic image transmission method for wifi visual products, such as figure 1 shown, including the following steps:

[0029] 1. The mobile client starts the timer to count the number of complete image frames and the number of missing image frames received from the device every 1 second.

[0030] Due to the large amount of complete image data collected by the device, it will be split into several packets and sent. Each packet of data will carry the current frame sequence number, the total number of packets, and the current packet sequence number.

[0031] Specifically: a. The mobile client receives a packet of data, and judges whether it is the first packet of a frame of image, that is, the current packet sequence number is 1, which represents the beginning of a new frame of image.

[0032] b. If the current packet number is 1, record the current frame number FrameNumber, the total number of packets, the current packet number, and the current ...

Abstract

The invention provides an image dynamic transmission method for wifi visual products. The method comprises the following steps: S1, a mobile client starts a timer to count complete image frame number data and missing image frame number data received from a device end every one second; s2, the mobile client calculates the expected transmission frame number in the next second according to the image frame number data counted in the step S1; s3, the mobile client sends the expected transmission frame number calculated in the step S2 to the equipment end; s4, after receiving the expected transmission frame number sent by the mobile client, the device side adjusts and transmits the image frame number according to the expected transmission frame number; the mobile client is adopted to analyze current data loss and frame dropping conditions, dynamically send an instruction to the equipment end, adjust the number of frames sent per second, adjust the data volume of images sent per second, reduce data loss and frame dropping conditions, and prevent macroscopic image jamming conditions.

Description

technical field [0001] The invention relates to the technical field of image transmission, in particular to a dynamic image transmission method for wifi visual products. Background technique [0002] In wifi visual products, the mobile client and the device are directly connected through wifi. The device is used as an AP (access point), and the mobile client is used as a STA (station). There is a camera on the device, and the camera can be The collected images are transmitted to the APP of the mobile client and displayed to the user. [0003] At present, the device generally uses a fixed number of transmission frames to transmit images. For example, 20 frames of images are fixedly transmitted per second, and the camera is fixed to collect and transmit images with a resolution of 640*480. However, different images are compressed due to differences in color and details. There will be a difference in the image size, which may be between 10kB and 30kB, which leads to a differen...
