The present invention be designed using high speed camera and high speed hard-disk storage equipment it is a set of based on computer vision/figure
The basic data acquisition device of the relevant auxiliary driving of automobile or Function for Automatic Pilot exploitation or test is carried out as processing.With height
Sample frequency ensure that the analyticity of data, and more camera devices is supported to record simultaneously, can from automobile different perspectives into
The acquisition of row data is the acquisition device of a set of basic data needed for multiple functions developmental research, such as lane detection, letter
Signal lamp detection, blind area object detection etc..
As shown in Figure 1, the embodiment of the present invention provides a kind of SPEED VISION road data acquisition device.Device includes:
Two high speed cameras and a general camera, two described high speed cameras or so are arranged side by side, and shoot vehicle respectively
The high frame per second road video data of left and right side (including visual angle forward or to downwards angle of visibility).The high speed camera uses model
The high speed camera of Basler ace-acA800-510uc, the general camera may be mounted at vehicle bumper, interior backsight
Mirror, Chinese herbaceous peony keep off the vehicles any position such as side or vehicle rear bumper, for shooting the view of the low frame per second road in camera fields of view
Frequency evidence.The general camera uses the common camera of model FLIR BFLY-PGE-23S6M-C.High speed camera is differentiated
Rate is set as 800x600, frame per second 500fps, and preservation format is RAW-Bayer.Common camera resolution ratio is set as
640x480, frame per second 30fps, preservation format are RAW-Bayer.The high speed camera and the general camera with USB or
